● Saves on substance – allows a lower substance than regular kraftliner
intended for contact with water
● Avoids tons of paraffin – free from non-renewable petroleum
● 100% renewable resource – biodegradability according to EN 13432
● Recyclable material from renewable sources – fully recyclable, made of
wood fibres
● Wood procured from sustainable resources – certified according to
FSC®
● No undesirable migration of paraffin – since the paper surface is treated
with non-migrating additives, there is no risk of any impurities originating
from the paper surface

Product benefits

● Strong water-resistant properties – top sheet offers water-resistant characteristics and excellent glueability properties for the base sheet
● Partly water resistant for several days – low water absorption, excellent strength even in high-humidity environments, and outstanding Cobb60 values
● Improved corrugator runnability – omission of wax-dosing units on corrugators can increase converting speed by 10-15% and save time otherwise needed for removing paraffin residues
● Safety and environmental issues – improved working conditions (no unpleasant paraffin odour) and reduced risk of fire at the corrugator
● Printability – unlike wax-coated papers, ProVantage Kraftliner Aqua has good printability

Effect on box parameters – tensile stiffness
The bottom of the corrugated box can be modelled as a rectangular plate ->
deflection d of the box bottom could be considered as deflection d of the
rectangular plate under load. Deflection of the plate is inversely proportional to
plate curvature R, bending stiffness Sb and tensile stiffness St.
Higher tensile stiffness St of the corrugated board (i.e. constituent liners St,
L1 and St, L2) would result in higher bending stiffness and lower deflection of
the box bottom!
ProVantage Kraftliner Aqua
Aqua paper grades Page 15
Effect on box parameters – tensile stiffness
BCT, or the maximum vertical load which the corrugated box can withstand, also depends on bending Sb (and tensile St) stiffness according to the McKee equation:
Boxes made of board with higher St,MD and St,CD would have lower bottom
deflection d and higher BCT!
In order fully to exploit the excellent characteristics of Pro Vantage Kraftliner
Aqua, the use of water-resistant glue is recommended.
BCT = C*ECTb 1-b *Z2b-1SbMD * SbCD

Technical comparison – water resistance
Performance of a corrugated board made of ProVantage Kraftliner Aqua could
be further enhanced if a water-resistant glue were used.

Technical comparison – MD/CD tensile stiffness after Cobb 2 hours
ProVantage Kraftliner Aqua vs. ProVantage Kraftliner 170 g/m²:
● Before Cobb 2h: same MD/CD tensile stiffness in the dry state
● After Cobb 2h: MD/CD tensile stiffness of ProVantage Kraftliner Aqua
was approx. 40% higher than that of ProVantage Kraftliner

Technical comparison – Which paper to choose for humid conditions and
in cases where direct contact with water is possible?
After direct water contact:
● ProVantage Kraftliner Aqua adsorbs less water than ProVantage
Kraftliner
● MD/CD tensile stiffness of ProVantage Kraftliner Aqua is 40% higher
than that of ProVantage Kraftliner
● Burst strength of ProVantage Kraftliner Aqua is twice as high as that of
ProVantage Kraftliner
Boxes made of ProVantage Kraftliner Aqua adsorb less water and offer
higher BCT and tensile stiffness in humid conditions
Boxes made of ProVantage Kraftliner Aqua protect contents better than
boxes made of ProVantage Kraftliner!

● Leakage point** after 3 days
● Higher stiffness values in CD
● Outstanding, higher burst values
● Up to 35% lower water absorption

“When we need moisture resistance in fruit and vegetable boxes, we use
Aqua products…”
“…for some small farmers, the harvest of a few days counts for a big part of their
yearly income. Therefore extra security of box resistance is required. With
Aqua products we can offer it…”
“Aqua offers better water resistance against wet berries. It keeps good
stacking strength and low bottom deflection when wet berries are stored
and transported…”
“Strawberries are harvested mostly direct to the corrugated boxes. Berries are
cooled to 0-5 °C and within 3 days transported to shops and customers”

● Poland is the largest producer of apples in Europe and the third largest in the world.
● 1.2 million tons of apples were exported in 2012 (approx. 40% of total production).
● Prior to dispatch, apples are washed and stored in cold rooms for up to nine months.
● Apple packaging materials must withstand storage in varying humidity conditions and temperatures.
Kraftliner Aqua is an ideal solution for
apple packaging!
