Additional Label Topics

PET Technical MeetingJune 4, 2020

Sub-team participants

• Mitch Rackovan• Chris Bradley• Elizabeth Yerecic• Kyle Strenski• John Standish

Discussion topics

1. Simplify “approvals” for label suppliers - 1300 pressure sensitive label converters in the US• Those that make labels for PET thermoforms• Those supplying to smaller and regional brands

2. APR Guidance on paper labels• Pressure sensitive • Cut and stack• Wrap around

Simplification approaches

• Ink and label company partnerships• Ink qualifications on a “generic” label• APR review and listing as done several years ago for thermoform labels and a

“benchmark” style test

Paper labels

• Paper labels today are said to cost less than BOPP film labels• Paper pressure sensitive label components include:

• Adhesive• Paper stock – paper fibers, binders, coatings• Inks• Lamination film is some cases

• Lab work with paper pressure sensitive labels has shown:• Better adhesives• Better paper stocks• Better inks

Some additional recommendations

State clearly that film labels as preferred, paper labels are detrimental to PET recycling. That said:• Include a section on paper pressure sensitive labels in the “Pressure Sensitive Label

Resource Document and encourage “better” paper pressure sensitive labels and use of the Benchmark Test to select adhesives, paper stock and inks.

• Encourage use of the Benchmark Test to select cut and stack adhesive, paper, and ink options.

• Invest in lab work to demonstrate the impact that paper and film labels can have on PET recycling and the importance of selecting the right label materials.

Oxygen Ingress Barrier PET Containers

(OIBPC) that can be recycled with the

Clear PET Recycling Stream

OIBPC – Today • Oxygen ingress barriers are essential to provide the required shelf life

to PET bottles for certain oxygen sensitive products

• Brands are expected to recycle 100% of PET packaging while using 25% PCR content in new containers

• Retailers require a “How-2-Recyle” label on containers • A variety of oxygen barrier technologies are available:

Scavenger/Passive Barrier Materials - Multilayer Containers - Coatings

• Recyclers are cautious to avoid any contamination of the clear rPET stream, in particular with color and haze

• Perception is that most Oxygen Ingress Barrier PET Containers (OIBPC) are not recycled in the USA today

Ø Need data to verify the state of OIBPC recycling in the USA

Perceived Obstacles

There is limited understanding of the impact of various OIBPC’s on the PCR rPET quality at recyclers and the global rPET stream • Color and haze specifications for clean clear flake by brand owners

• Potential yellowing, haze, IV loss or black specks during recycling

• Different OIBPC materials may have different impact on clear rPET

• Some OIBPCs can reduce quality and value of rPET • Most OIBPCs do not pass APR Critical Guidance Recognition today

• Inability to differentiate between “The God, The Bad and The Ugly”– In particular, which ones are preferred, detrimental and/or can not be recycled

• Difficulty to effectively sort and/or separate OIBPC containers

Ø Need to verify perceptions and assumptions by generating data

A Better Future Success Criteria

• Enable OIBPC to be recycled with the clear rPET stream• Allow for How to Recycle Label (H2R) from SPC • Minimize use of OIBPCs that have negative impact on rPET stream• Increased bale yields related to recycling of OIBPC

Potential Measures

• Number of OIBPC applications that receive APR recognition and/or H2R label• Number of OIBPC that obtain brand commitment from brand owners • Total PET amount from OIBPC packages that is recycled • Increased bale yield recycling of OIBPC

Objectives Balance

Cost – Clarity – Product Protection – Shelf life with

Impact on rPET – APR Recognition – H2R - Closed-Loop Recycling

• Cost effective product protection during entire shelf life in clear PET container • Minimal yield loss to bales and minimal contamination to the rPET stream• OIBPC materials/technologies that are recognized or accepted according to APR’s design guide • Commitment of brand owners to preferred OIBPCs in their packaging • Clear communication to recyclers which OIBPC can actually be recycled • Commitment of the recyclers to recycle the recommended OIBPC

Milestones1. OIBPC made from barrier materials that

– provide the required performance over the entire shelf life– are commercially available and economical overall – have a minimal effect on the overall clear rPET stream

2. APR Critical Guidance criteria that can differentiate between

1) Preferred – 2) Detrimental – 3) Not Recyclable

1. APR Critical Guidance recognition for preferred OIBPCs that meet criteria

2. H2R label for OIBPC that render detrimental but that are/can be recycled

3. Commitment of brands to preferred OIBPCs that are recognized by APR

4. Clear communication to recyclers which OIBPC can or can’t be recycled

Path Forward1. Update list of current oxygen ingress barrier technologies – in progress2. Verify current recycling practice of OIBPC with industry survey 3. Define impact of various OIBPCs on bottle and color haze 4. Define impact of various OIBPC on flake color at 2% and 10% LDR in PET 5. Convene technical sub group with the following members:

Mike (lead), Byron, John, Kamal, Chris, Wei, Frank S., Frank E., Alan, …

6. Verify market penetration of OIBPC in total PET Develop a list of containers using oxygen ingress barrier technologies Estimate share of all OIBPC in total PET in the USA

7. Benchmark other organizations and their procedures in the ROW8. Develop and present project scope and budget for above tasks to obtain APR

commitment APR meeting in October

Next Steps - 1Verify current industry practice with various OIBPC!

• Conduct APR Recycler survey on OIBPC:– Which OIBPC bottles do you know in your stream?– How do you determine which bottles are OIBPC? – Which OIPBC bottles do you sort out?– Which method allows you to decide which bottle to sort out?– Which pf theses bottles go to the colored PET stream? – ….

• Need PPR from Working Group to lead: – Finalize design of questionnaire– Compose addressee list and send questionnaires– Collect, compose and analyze responses – Compose application list of OIBPC – Consolidate and present findings to Working Group

• Timing: Completion by June 26th 2020

Next Steps - 2Define bottle and color haze impact of various OIBPC!

• Conduct Oven test of various/representative OIBPC– Ensure a industry wide and representative sample selection

• Use data from survey and brand owner input – Include control bottles made from various standard PET resins– Decide how to procure the bottles– Decide on testing location (Residential oven works fine) – Take images and measure color and haze – Compose and compare data and establish industry overview

• Need PPR from to Technical Team to lead and coordinate– Coordinate efforts and ensure proper execution – Consolidate and present findings to Working Group

• Timing: Completion by July 31st, 2020

Next Steps - 3Define impact of various OIBPC on flake color at 2% and 10% LDR

• Conduct plaque color and haze measurements– Ensure a selective sample range from oven test – Include standard PET control bottles – Blend above samples at 2% and 10% with 98% and 90% control respectively – Extrude plaques for color and haze measurement – Decide on testing location – Professional lab recommended – Take images and measure color and haze – Compose data and establish industry overview

• Need PPR from to Technical Team to lead above effort– Coordinate efforts and ensure proper execution – Consolidate and present findings to Working Group

• Timing: Completion by August 31st, 2020• Resources: Need funding for testing at APR recognized testing lab
