Made-to-measure products and standardised protective packaging for archives, libraries,

museums and collections

Protective Packaging for cultural assets – why?

Two of the most important causes of damage to original documents are the storage and transport conditions. Un-protected archive objects, books, photographs, maps etc. are constantly subject to environmental influences such as dust and light. Whether these objects are removed from the shelf or returned this will always lead to some damage being caused, and on transport in the reading rooms even more so.There are certainly many more ways to cause damage to objects and not everything can be taken into consideration or influenced. However, damage arising from unprotected storage conditions or transport in unsuitable packaging can be avoided with very little effort and at fairly low cost.– Suitable packaging keeps dust and light at bay and provides protection during movement and transport. – Any changes in the climate conditions (temperature, humidity) either in storage rooms or during transport are reduced. – If there is formation of mould, objects which are packed have a certain extra protection. – Even endogenous processes such as aging of paper or the build up of acidification can be delayed, because these

processes are slowed down by the absence of light. – If there is a disaster, it makes a great deal of difference whether water falls directly onto a file, book or textile, or

whether the protective box becomes wet first. This factor becomes even more important when it comes to the effects of fire. Protective packaging can sometimes completely protect the item from smoke and fumes and even the effects of heat can be lessened to some extent.

Every object should be stored individually under the best possible conditions in its own container in order to protect the object from dust, light, fluctuating climate conditions and other environmental factors, and from the effects of micro-organisms and pests.

Which Material is Suitable?

Every box is able to provide some protection. It is able to protect the object from mechanical damage during transport and reduces the damage caused through minor accidents (e.g. dropping onto the floor), it can protect from dust, light and other environmental factors, in an emer-gency it can provide limited protection against water. That is sufficient and can be provided by simple packaging used for short periods, e.g. for transport. However, a storage box for archival purposes has to meet higher requirements. The articles to be stored are made of paper and must be kept for long periods of time. For storage boxes and folders used in the daily filing department requirements need not be as demanding as these items will be stored only in the short and medium term and will be selected after a certain deadline.

Whether an archival box aids or whether it harms the article being stored within depends completely on the actual material being used. When the phenomenon of acid migration became known, both the manufacturer and the user of archival boxes and museum cases had to revise their opinions: cardboard with an acid content (and at the time this meant every box on the market manufactured from grey card) can cause damage as the acid present migrates and permeates the object being stored within. In this way even paper being stored, although containing no acid-building components and therefore not directly endangered, could be affected through acidification in the long term.Initially this led to the requirement that all packaging card-board had to be acid-free. Almost immediately this led to a further improvement in the quality whereby a reserve of alkali was included in the material. This was able to neutralise the acidic component which might be present in the object or which might come from the environment. It even became possible to use materials which contained some components which might produce acid (e.g. recycled paper).The acid particles contained could be neutralised for a period of time through the use of alkali buffer materials.

This development led to ever higher demands in terms of quality: The materials to be used must not only be free of acid but they must also be void of any components which themselves could later lead to acid being produced. Paper materials which conform to these requirements can be termed „age-resistant“. In order to fulfil these high quality standards, paper manufacturers are not only prevented – as is usual in the production of acid-free paper – from using any form of woody material, but also forbidden from employing recycled paper, because the exact composition of this cannot be determined and it must always be assumed that this contains a mix of wood-containing (ligneous) and acidic materials.

Age-resistant paper is defined under German Industry Standard DIN ISO 9706 and this is the basic precondition for the manufacture of card, corrugated cardboard or museum board with the corresponding properties. When assessing paper board these criteria – as far as is possible

– are taken into consideration even if the standard is not directly referring to card.

The most recent definition of requirements relating to permanent paper materials is laid down in DIN ISO 16245. This standard distinguishes between paper materials for boxes and folders and it subdivides the materials for bo-xes into Type A and Type B. Requirements for permanent paper materials are formulated as Type A. The same stan-dard defines paper materials whith lower quality as Type B, which can nevertheless be used for specific purposes of archiving. The former, completely well defined statement, which says that paper materials are permanent if they fulfill the requirements for DIN ISO 9706, is now diluted. Unlike as in DIN ISO 9706, the confirmation that papers comply with DIN ISO 16245 is now no longer enough to charac-terize them as permanent. Permanent paper materials have to satisfy DIN ISO 16245 A. In addition to DIN ISO 9706, this standard contains guidelines for bleeding, the prohibition of optical brighteners, and a strictly prescribed Cobb-value (value for the entry of humidity from the envi-ronment into the cardboard).

Made-to-measure Packaging

Books, archive materials, documents, certificates and deeds, even textiles and all manner of objects in historical collections, come in all shapes and sizes. So, it is natural that as well as providing packing materials which are age-resistant the particular container for the object in question should be as individual as possible and made-to-measure in order to provide protection not only from damaging environmental influences but also to provide mechanical protection.These considerations formed the basis for our decision, as far back as 1991, to begin inhouse development of a computer-supported manufacturing process for the pro-duction of made-to-measure protective packaging.The actual production process to manufacture a box is the same as for every other CAD/CAM-application: The desired design is selected from the menu in the CAD program, the suitable material is chosen (because of its thickness) and the measurements of the object are entered. The software then calculates and determines the actual construction of the box, i.e. the course of the cutting and creasing lines.

This information is then used to control the cutting and groove plotter, which then produces a box or folder from the raw sheet of cardboard. In the course of this, first the creasing lines are created and then the slots cut out.

A variety of different tools for cutting and crease-making are available for processing – depending on thickness and kind of material.

On completion of the cutting and creasing steps the box is separated from the material to be discarded.

The box only needs to be assembled. In general, boxes are delivered as flat sheets and can be assembled by the customer. Very large boxes, made of several separate parts and then glued, must be supplied ready-assembled.

The manufacture of an individual protective box takes between 3 and 6 minutes depending on the design; big boxes and complicated special designs might take longer.

This manufacturing technique works only on archival car-ton or corrugated cardboard. Solid board materials can be cut, but the creases are not sufficiently scored.

SchemppBox – Product Classification

The question of which SchemppBox is best suited to fulfil a certain task depends on its function, which is largely determined by its design. When choosing a suitable box, the design must be selected first, before further properties, e.g. the material, can be decided.SchemppBoxes (SB) are classified according to their basic design form (boxes with lids, clamshell boxes, slipcases etc.), which form a product group (e.g. SB 3: clamshell boxes). Within each group you will find the corresponding model you are looking for.The product classification „SB 31“ thus refers to: SchemppBox Type 3 (clamshell boxes), model 1 (basic standard).

SchemppBox Type 0: Box accessories– SB 01: Floor insert, intermediate layer insert– SB 02: Filler, flat plan aid– SB 03: Lifting aid– SB 04: Coin tray etc.– SB 05: Compartment insert– SB 06: Mounting material for deeds and seals– SB 07: Layers– SB 08: Stackable tableaus

Product Description SchemppBox Type 0: Box accessories

Design– SB 01: Floor insert, Intermediate layer Insert – SB 02: Filler, flat plan aid– SB 03: Lifting aid– SB 04: Coin tray etc.– SB 05: Compartment insert– SB 06: Mounting materials for deeds and seals– SB 07: Layers– SB 08: Stackable tableaus

UsageThese designs have no function on their own but serve as accessories for other types of boxes. They improve the properties of the box being used or make them more convenient and easier to use.The Floor Insert (SB 01) increases the carrying properties, i.e. the amount that can be carried or stored, while the Intermediate layer Insert allows individual objects within the box to be separated from each other.Fillers or Flat plan aids (SB 02) are useful when the objects within the box do not completely fill the box. These ac-cessories, for example, prevent a collection of numerous, thinner documents from sinking and buckling when the box is set upright.With a Lifting aid (SB 03) objects can be more carefully inserted into a box and later taken out.Trays (SB 04) with precise made-to-measure cut-outs allow individual items or collections of objects to be safely kept in the box (e.g. coin tray, which can also be used to store medals or loose seals).Compartment inserts (SB 05) are used to separate a box or even large plan drawers or similar into individual, smaller sections, so that smaller items such as seals, archaeological finds etc. can be stored.Mounting materials for deeds and seals (SB 06) are of help to fix these objects into the boxes.Layers (SB 07) are put into the boxes so that the objects are located safely and in order to prevent them touching the bottom of the box (e.g. layers for tubes).Stackable tableaus (SB 08) enable the storage of multiple flat objects (e.g. deeds) in a box one above the other.

DimensionsThese accessories can be produced in almost all sizes. A maximum size for an individual piece is only dictated by the largest size of card material available. Extra large pieces must be made up of more than one sheet and glued together.

UsageFolding boxes can be used in almost all situations. Books, files and loose sheets can all be safely stored in them. Suited for vertical or horizontal storage.One of the biggest advantages besides their being very handy (the box is closed around the object, so no compli-cated box construction) is that they are exceptionally suit-able for flatter objects. There is no minimum thickness of the item for storage, therefore this folder-style box is often chosen in preference to other designs where the object thickness is under 20 – 25 mm.

DimensionsThese boxes can be produced in almost every format. The folding box is especially useful for extremely thin items, where boxes with lids (free or hinged) cannot be used. The maximum size for an individual piece is only dictated by the largest size of card material available. Extra large boxes must be made up of more than one sheet and glued together.

Assembly instructionsThese boxes can normally be assembled quite quickly and easily. As their name suggests, these boxes are folded around the object (e.g. a book).Boxes SB 11 and SB 12 in large formats and with very thin contents require somewhat more care in construction. The creasing lines for folding lie very close together, which can lead to problems when folding the box.Depending on the actual format of the object to be stored, insertion of the fold-in flap might need some practice. Generally, the creasing lines on the closing flap must first be folded in both directions before first use (always towards the inside first, then carefully outwards, use a folding bone if necessary).

Product description SchemppBox Type 1: Folding boxes

Product description: SchemppBox Type 2: Boxes with lid

DesignBox with lid, two components (base and lid). Pure plug-in design, no metal parts, staples etc. Can be delivered in assembled form, glued as requested.

– SB 21: Standard model, two opposite sides of both base and lid are double-strength card (folded over); the closed box thus has three-layer sides increasing strength

– SB 22: Box with lid and strengthened side walls, all four sides having folded over double-layer card; the closed box thus has four-layer sides increasing strength

– SB 23: SB 21 design but glued– SB 24: SB 21 design, one longer side of the base can

be folded out– SB 25: SB 22 design, one longer side of the base can

be folded out– SB 26: SB 23 design, one longer side of the base can

be folded out– SB 27: SB 23 design, side walls and bottom reinforced– SB 29: Box with lid with single layer for all sides, fold-in

flap for closing

UsageBoxes with detachable lids are ideal for archiving all sorts of written materials, museum items of all types, e.g. textiles or realia of any nature, archaeological treasures in a horizontal state.

DimensionsBoxes with matching lids can be produced in almost every size. The interior height, however, should not be below 25 mm as the box is then more difficult to set up. The maximum size for base or lid is only dictated by the largest size of card material available. Extra large boxes must be made up of more than one sheet and glued together. Standard sizes are available for conventional sizes used for archival purposes.

Assembly instructionsBoxes with detachable lid are simple and easy to assemble where the box is not of an extremely large size. The greater the filling height of the box, the easier it is to form the side walls into shape. Folding down the side walls in boxes with low filling height requires great care.Assembling boxes with a special design, e.g. lidded boxes with additional divider, is a little more complicated and requires a feeling for the material and practice to achieve the required result.

Product description: SchemppBox Type 3: Clamshell boxes

DesignClamshell box, single sheet construction. Pure plug-in design, no metal parts, staples etc. Can be delivered in assembled form, glued as requested.

– SB 31: Standard model, both longer sides with double thickness walls (folded over); the closed box then has four-fold strength to the front, double strength left and right sides and single thickness to the top, bottom and rear

– SB 31A: Special design with filing mechanism, bottom reinforced with solid board

– SB 32: Clamshell box with strengthened sides, three side walls with double thickness (folded over); the closed box then has four-fold strength to three sides and single thickness to the rear

– SB 33: Clamshell box with strengthened sides, floor, lid, and rear. All parts glued.

– SB 34: Clamshell box with fixed side walls– SB 35: SB 34 design with fold-out side wall

UsageClamshell boxes are used for a wide variety of purposes. Books and other objects with a binding or which are held together can be stored vertically. Loose sheets, correspon-dence, prints, deeds and other documents are usually stored in boxes with folding lids horizontally. A particular advantage is the possibility of holding the object from the left and inserting or removing it carefully when the box is open.

A special design of clamshell box is that which incorpo-rates a filing mechanism (SB 31A), this makes it simple and easy to store items such as photos, bank notes, cor-respondence and other sheets in their protective covers.

DimensionsClamshell boxes can be produced in almost every size. The interior height (depth), however, should not be below 25 mm as the box is then more difficult to assemble. The maximum size for base or lid is only dictated by the largest size of card material available. Extra large boxes must be made up of more than one sheet and glued together. Standard boxes are available for conventional sizes used for archival purposes.

Assembly instructionsClamshell boxes require extra care and attention when folding the sides: if the two creasing lines to the rear of the box are insufficiently bent over before begin then the box might not close properly, as the lid stands up. The sides of clamshell boxes are also prone to expand outwards, as they are only attached on one side from the design and are not anchored in position to the rear.The deeper the clamshell box the easier it is to assemble the box properly.

Product description: SchemppBox Type 4: Archival boxes

DesignArchival boxes with front or side opening flap. Pure plug-in design, no metal parts, staples etc.– SB 41: Archival box for horizontal storage and front flap

(attached)– SB 42: Archival box with flat insert attached to front flap – SB 43: SB 42 design with four-sided cassette insert– SB 44: Archival box for vertical storage with front flap

on one side– SB 46: Archival box for vertical storage with flap on the

top of one longer side– SB 47: Archival box for vertical storage with flap on one

shorter side

UsageThese boxes are popular in archive offices and in registry departments, as well as for storing items in library and museum collections in order to store file correspondence, brochures, newspapers and magazines, loose sheets etc. Individual items can be stored flat (SB 41 to 43) or upright (SB 44, 46, 47). SB 41 can also be produced as a long narrow box to hold long or round objects.

DimensionsArchival boxes can be produced in almost every size. The interior height should not be below 50 mm as the box is then more difficult to set up. The maximum size for base or lid is only dictated by the largest size of card material available. Extra large boxes must be made up of more than one sheet and glued together. Standard boxes are available for conventional sizes used for archival purposes.

Assembly instructionsOur archival boxes with a front opening flap in versions SB 41 to 44 require the most care and attention when being assembled. We strongly recommend the use of a bone folder, in order to make it easier to pass the flaps into the appropriate slots without damage.The two flaps to the front are not designed to keep out dust etc., but are part of the side wall strengthening and must be carefully inserted when setting the box up.The front flap must be carefully folded along both crea-sings otherwise the box will not close properly. Once the box has been folded together, any problem with the front flap can no longer be corrected.

The designs for horizontal or vertical storage SB 46 and SB 47 are fairly easy to assemble after one or two trial attempts. For both boxes a loose insert is included which can be used after assembly in order to strengthen the box floor and to cover the design elements.

Product description: SchemppBox Type 5: Slipcase, magazine box

Design– SB 51: Slipcase. Pure plug-in design, no metal parts,

staples etc. Can be delivered in assembled form, glued.– SB 52: Magazine rack box for upright use. Pure plug-in

design, no metal parts, staples etc.– SB 53: Slipcase with combined magazine box – SB 54: Book shoe, glued

UsageSlipcases (SB 51) are ideal for books where some pro-tection is necessary but the spine should be visible on the shelf, e.g. to give the appearance of a historical library. They can also be used to preserve several thinner books of the same height, e.g. small set or to store brochures.The upright magazine racks (SB 52) are primarily used to store a range of individual items, e.g. brochures, maga-zines or similar paper objects.The combination of a slipcase and a magazine box as insert (SB 53) is frequently used to preserve particularly valuable or sensitive books, brochures, magazines, loose collections of papers etc. Book shoes (SB 54) are open up front and at the top. They provide a simple protection of covers in setting and lifting off the shelf.

DimensionsThese types of boxes can be produced in almost every size. The thickness of the object, however, should not be below 30 mm for the magazine box or 10 mm for slipcases as the box is then more difficult to assemble. The maximum size for base or lid is only dictated by the largest size of card material available. Extra large boxes must be made up of more than one sheet and glued together. Standard sizes are available for conventional sizes used for archival purposes.

Assembly instructionsFor SB 51 it is important that the double row of creasing lines are carefully folded otherwise the slipcase is difficult to fold together and tension will be caused in the upright case making the slipcase lean to one side.Magazine box style SB 52 requires some practice at slotting the four floor parts together. In order to ensure a completely flat floor in the constructed box, an extra insert, supplied, is placed in the floor of the box.

Product description: SchemppBox Type 8: Tubes

DesignTubes of spirally wound cardboard, with or without caps.

UsageCardboard tubes are used primarily for the safe storage of large rolled objects, e.g. maps, plans, charts, drawings etc., which can be inserted into a tube.Tubes can also be used as the centre piece around which other items are rolled, to store flags, rugs and other collec-table items for example.Fragile historical maps, too large for storing in map drawers etc., can be wrapped around a tube with a large diameter in order that only a limited amount of bending pressure is applied to the material and tension during rolling and unrolling is largely avoided.

ManufactureThe tubes are manufactured of age-resistant museum quality carton in a spiral process.Plastic covers for the ends can be supplied.

DimensionsThe following sizes have been found to be very popular for the storage of rolled items such as maps and charts, posters, large format printed items etc.:

Diameter Material thickness Caps 75 mm 1.5 mm yes 100 mm 2.0 mm yes 150 mm 2.5 mm yes 200 mm 3.0 mm yes 250 mm 3.5 mm yes 300 mm 4.0 mm 400 mm 4.5 mm

Tubes are available in lengths of 2 m and 4 m (diameter 75 mm only in 2 m) and can be cut to the required length.As well as the standard sizes offered above, tubes can also be specially supplied to order (Diameter 50 up to 600 mm, wall thickness 1.5 up to 10 mm, length 30 cm up to 6 m).Please note: the preparation and delivery of specially ma-nufactured tubes either as individual pieces or in small pro-duction numbers is labour-intensive and therefore costly.Therefore custom-made products can only be produced in high quantities.

Material specificationsMuseum quality carton, age-resistant according to DIN ISO 9706– natural white– 1.5 mm to max. 10 mm– acid-free, free of lignin– pH-value ca. 8.9– alkali reserve of calcium carbonate > 4%– neutral glue

UsageFolders and covers are usually used as an added inner packing within boxes. Folders (SB 91) are often used to preserve and keep separate single items or thin collections. The advantage over normal file folders is that the three flaps prevent material falling out.Plain envelopes (SB 92) are normally single folded or creased centrally. Single sheets can be inserted or thin collections of papers. Envelopes for individual documents are made of archival paper and can be used as inner packing inside a folder, e.g. to keep particular sheets safely stored.Map and print folders (SB 93) are usually found in larger sizes and serve to protect large format documents such as maps, technical drawings, posters, prints etc. The four-flap folders (SB 94) are ideal for the storage of glass photographic plates.Envelope-style covers (SB 95) of archival paper, photo-archive paper, Melinex or Pergamin are frequently used in the area of photographic archiving, and can be used to preserve a single leaf, photo or item within a larger box.Folders with ribbons (SB 96) are usually used to tie pack-ages of files and keep them together.

DimensionsThese types of items can be produced in almost every size. The maximum size is only dictated by the largest size of card material available. Extra large items must be made up of more than one sheet and glued together.

Assembly instructionsAll of these types of product are simple and easy to assemble, and the flaps can be folded and prepared in any sequence. However, the usual care must be taken in advance when folding along the creased lines so that the container when filled has a regular shape and remains stable (especially true of the folders with several creasing lines for variable filling heights).From top to bottom: SB 91 of archival carton grey, various dimensionsSB 92 of archival carton 120 g/m² blue greySB 93 of B-flute 3.0 mm grey/whiteSB 94 of photo archival paper 90 g/m² or 120 g/m²

Instructions for Assembling SchemppBoxes

Customers will usually receive their SchemppBoxes as a flat pack. However, we are also able to deliver our boxes in ready-constructed format where desired by the customer. Sometimes the particular design requires gluing, e.g. for large boxes made up of more than one sheet, and these will be supplied glued and folded into the complete box. Assembling the boxes is more or less complicated, depending on the design and size of the box. It will require a certain amount of practice as well as a feel for the material which is used.

The current opinion among experts is that no metal parts should be used if possible and that is largely the wish of today´s customer and furthermore that either no glue is used or, where unavoidable, as little adhesive as possible is employed (e.g. for very large boxes, which cannot be constructed from a single sheet of card). Today customers increasingly demand a box which can simply be folded and slotted together. Naturally this has consequences for the design of the box, as this is subsequently more complicated than one which is held together with staples or adhesive. This idea should be kept very much in mind when it is found that the box is somewhat difficult to assemble.

In order to assemble the box structural correctly and to give the finished box a better appearance we recommend that a bone folder is used during assembly.

1. The cutout is laid with the coloured side (grey or blue grey) or the side with additional covering face down onto a smooth working surface. The work table should be absolutely clean, so that no dirt or damage will affect that side which will later be the outside of the box (e.g. because of dirt or impressions left).

2. Now the cardboard is bent over completely (180°) to-ward the middle of the cutout along the creased lines. The material has a natural inner restoring force which is thus disabled or at least reduced such that assembly of the finished box is made possible and a perfectly rectangularly-shaped box can be formed. Especially those boxes with long sides tend to bow where this restoring force is not sufficiently broken at these points. Folding over the side walls of a box is more difficult the longer the side or the narrower the side is. Long and narrow boxes are particularly vulnerable and there is the danger that the side becomes vertically creased during folding over. Therefore special care must be taken and the folding should be carried out slowly and in more than one step so that there is no danger of too much tension being caused in the material.Extra care must be taken where there is a double row of creasing lines. The material should be carefully folded over and bent along both creasing lines equally. How the material behaves along these lines depends on whether they lie along or at right angles to the direction of the corrugated paper layer. Double creasings at right angles to the corrugated are largely easier to fold and run evenly. Where the double creasing rows lie parallel to the corrugated then the card tends to fold over either in only one of the creasing lines or that creases occur across the material between the lines of fold. As soon as it becomes apparent that the material will not fold smoothly along these lines, folding should be discontinued and with the help of a bone folder the creasing lines should be deepened; either the weaker of the two lines or, where folding is outside the fold line, both creasing lines.

26

The design calls for the material to be folded over to 90° along both creasing lines. These double creasings can always be found where the side wall must be folded over once completely over the entire height to prepare for the later insertion of the flap on the floor of the box into the resulting slot, thereby allowing the box to be constructed correctly.

This function is then fulfilled when the double creasing is correctly folded over. Even a small deviation at this point means that either increased tension will be caused to the floor of the box (leading to bending or misshaping of the flaps or that the side walls will bend) or it will not be possible to insert the flap into the box floor or that not enough flap will be inserted to give the box stability. Consequently, folding over these double creasing lines will decide whether the box can actually be assembled correctly at all.

right wrong wrong wrong

3. The box can now be assembled. Most designs are such that the beginner can clearly see which parts of the construction belong together and in which sequence flaps and double side walls must be folded over each other, in order that each and every piece carries out its task and a stable, finished box is produced.

Special instructions relating to the design can be found in the descriptions of the individual box types.

The bone folder is also useful when assembling the box, e.g. in order to press flaps into the correct slot.

4. Finally – where required or where necessary – some more improvements are possible.

– Double creasing lines along side walls which were not absolutely correctly folded over allow a small amount of correction after assembly using the bone folder. Tension in the material can thus be reduced or the stability of the connection enhanced.

– Remaining restoring forces, e.g. at the back of the clamshell boxes, can be reduced by counterpressuring with the bone folder. – The leading edge of the corrugated card can sometimes be somewhat sharp. This can be avoided by smoothing along the edge with a bone folder.

27

Individually tailor-made boxes or folders cannot normally be realistically considered for very large numbers of ob-jects for financial reasons. Nevertheless, it is possible, even here, to considerably improve the storage conditions in this sector by careful choice of suitable materials and the use of reasonably-priced standard boxes and folders.

Archiving Photographic MaterialsA special case under the heading of protective packaging for valuable items is the storage of photographic docu-mentation. Here we include films, negative strips, paper photographic prints, contact prints, glass plates, slides and more recently also digital prints. Whereas conventional archive and library collections are comprised mainly of paper materials, photo-documentation involves a whole range of different materials, a result of the tech-nical developments which have been made since the beginnings of photography. To preserve such, to a large extent, extremely fragile materials over long periods of time poses an enormous challenge in the field of preservation and conservation. There are considerably more demands placed on such items both concerning the storage conditions and the handling as on conventional archive and library materials. As well as the provision of stable environmental conditions, the choice of packaging is of considerable importance in providing protection against physical damage and against chemical change.

The following basic rules apply in the planning, manu-facture and implementation of protective packaging for photographic documentation items:– All items should be packed individually to ensure no interaction of any chemical components. Physical damage can also be excluded (e.g. when two prints rub against each other then the upper, photographic layer of the lower print can be scratched, this is even more of a problem where several glass plates have been stored in the same packaging). – It does not make sense to have individual packaging for small items. Therefore, some sort of packaging is required for several individual items which ensures adequate protection from mechanical forces but also allows ease of handling in terms of storage and transport.

– Whereas packaging materials for conventional archive and library collection items contain an alkali buffer layer as additional aid in the prevention of acid accumulation in the paper and as protection against environmental influences, photographic materials must not come into contact with this, as a possible chemical reaction between the buffer substance and the chemicals present in the photographic layers cannot be completely excluded. Therefore, only non-buffer, ph-neutral paper materials are allowed to have direct contact to the photographic objects.

When considering the assortment of items to be packed together and the choice of materials this means that:– Each individual photo, every film or negative strip and especially every single glass plate must have its own sleeve or cover. The materials used here must not contain any alkali buffer material, but otherwise must fulfil the requirements for age-resistant paper materials as laid down in standard DIN ISO 9706, if they are made from paper. The proof that they contain nothing to chemically damage the photo object must be checked by carrying out a Photographic Activity Test (PAT). Our range of photographic packaging materials includes sleeves and four flaps made of non-buffered photoarchive paper, Melinex covers and Pergamin covers. – Schempp boxes are available in a wide variety of sizes and designs and are eminently suitable for the storage of several items together. Depending on whether the object should best be stored horizontal or vertically, the size and the number of individual items to be stored in one box, then lidded boxes SB 21, clamshell boxes SB 31 or boxes of a different design can be selected. The material is mainly age-resistant corrugated cardboard with an alkali buffer, but can also be supplied of age-resistant corrugated cardboard with an inner lining of photo archive paper.

Calculation of measurements

Basics – Internal measurementsThe basis for the construction of any box or folder is the external dimension of the object to be stored. The boxes are basically designed around the item so that the object size automatically becomes the internal measurements of the box.Measurements for additional inserts etc. will be taken into consideration during product calculation. An additional 1 mm is added to each dimension. Further additional measurements are not necessary as the object should fit tightly into its box or folder and not slip or slide when being moved.Objects which do not have an exact rectangular shape must be measured at their maximum dimension. Here care must be taken where there are projecting parts, e.g. book hinges. Even in cases where the book exerts some pressure the dimensions must be carefully taken at the maximum points without pressing down on the book itself. SchemppBoxes are made from light paper materials and are not really suited as a vehicle to press an item into a certain shape.

DimensionsProduction of the boxes is carried out according to the measurements usually given as follows:1. Height (for flat-lying objects: length)2. Width3. Thickness (for flat-lying objects: height = filling height)

Example: the measurements 300 x 210 x 70 mm would produce a box for a book in standard upright construction. The measurements 210 x 300 x 70 would produce a box in horizontal design.

External measurement of boxesThere are certain cases where it might be better to design boxes according to external measurements. This could be where the storage conditions, e.g. the size and shape of the available furniture such as cupboards or shelves, is to be used optimally and the boxes will be filled regardless of the actual shape and size of the objects to be stored. This type of design is usually only found where large amounts of the same kind of objects, e.g. files or correspondence, are to be stored en masse. An important advantage of the made-to-measure box, its precise construction to stored item, is therefore forsaken.
