Our Global Network We’ve Got You Covered
• Over 60 suppliers across the globe
• Connected to Innovation
• Multiple Solutions to Today’s Demands
3
Our Commitment to making the world a better place:
• Continually seeking new product offerings to enhance our ever widening basket of friendlier film products for our environment
• Focused efforts to identify and offer substrates that are produced with a lower carbon footprint and/or a positive impact on the waste stream:
• Recycled content or recyclable products
• Films made with resins produced by recycling oils and other byproducts
• Plant based (sustainable) virgin resins
• Newer technologies that can achieve biodegradable standards (time based disappearance from land fills)

The World and Now Plastics are reacting to this problem

Practical Analysis
Reality – Plastics cannot be replaced, nor should they be! ◦ 40 years to build the current infrastructure – hundred of billions of dollars invested
◦ Too many applications need sophisticated packaging
◦ Products have been fine-tuned to maximize efficiencies in processing and filling
◦ Barrier/shelf life requirements cannot be replaced in the near term.
◦ Costs – nearly all alternatives will be more costly in the short and medium terms – anywhere from 20% to 300%
◦ Is it a phase or a permanent trend???
Ways to attack the problems in a practical way: ◦ Use of virgin products will be reduced somewhat and use of PCR type products will increase – where possible
◦ Adjusted laminated structures to be same polymer family ( PE/PE, PP/PP, PET/HSPET, etc)
◦ Tonnages can be reduced – via downgauging of existing structures or development of alternative structures
◦ Switch to paper – not necessarily a better carbon footprint; forestry challenges due to higher demands
◦ Compostable products can be used in some applications; need to work around shelf life and film warranty periods
◦ Recycling and use of recycled products helps to some degree – but properties will diminish with each recycling period
◦ Government intervention to motivate creation of recycling systems
◦ New additives can make products bio-degradable
◦ Monolayers will improve recyclability of products

Market Trends

Post –Consumer Recycled (PCR) Films:
APET ---- RPET Trays and Thermoforming
PET Films (From mainly bottle reclaim process)
◦ Clear PET, MET PET, HS PET, Coated PET
PE Films
◦ PCR for Industrial, Pre-consumer for food packaging
PP Films
◦ PCR option newly emerging; small supply available
so initial lead times long. Hopefully will improve
over time but supply of recycled PP is smaller than
other polymers
BOPA/Nylon Films
◦ PCR made from reclaimed palm oil – food contact
certification available.
◦ Can adjust percentage of PCR/virgin resin to control
cost upcharge

Post Consumer Recycle (PCR) PET
Advantage of Recycled PET
• The fact that PET is 100% recyclable makes it the ideal sustainable packaging choice for business.
• Recycled PET has a lower carbon footprint than virgin PET.
• It converts post consumer waste into a valuable resource.
• Recycled PET can replace all or a proportion of virgin polymer in new packaging products.
• The products help business and organization deliver on corporate sustainability goals.
12
Post Consumer Recycled PE
• Post consumer recycled granules
• Usage 30% & 50% in PE film.
• Although the mechanical properties are like virgin PE granules, they create visual defects such as dots, gels etc. These visual defects are especially required from the end-user as a significant symbol of recycled raw material consumption inside the formulation. That’s why more gels, dots on the film are highly appreciated within the tolerance limits of process ability.
• No Food Contact Approval due to collected and post consumed recycled material’s sources. For this reason, usage is for non-food applications such as hygiene products.
13
14
In House (Pre-Consumer) Recycled PE
• 2 recycling unit
• Main purpose: Converting waste materials scrap films, edge trims or non-approved quality products into granule form again
• Granules are fed with some specific ratios in the formulation to produce the film with our own recycled PE
• Feeding % up to 50% of the total structure
• Food Contact Approval since %100 of these granules are converted from previous food contact approved raw materials • (Exxon, Dow, Borealis, Basell)
• No outside source used
14
15
Post Industrial Recycled PE
• Post industrial recycled granules
• Usage is 30% & 50% in PE film.
• Source: APK Company, separation of PA+PE Structure
• No change at mechanical properties
• No visual defects such as dots, gels, burnt materials
• Good transparency
• No Food Contact Approval due to solvent usage & residue at separation process of PA+PE structure.

WORLD CLASS FILM PRODUCTS FROM THE BIGGEST MULTI FILM MANUFACTURER IN SOUTHEAST ASIA
t
Our suppliers successfully produced the BOPA film, made with Ultramid biomass balance polymide on May 10, 2016, had the same properties as BOPA film with conventional polyamide based on fossil raw materials. The use of bio-feedstock helps save fossil resources and reduces greenhouse gas emissions.
v The WORLD’s 1st BOPA film by renewable materials

Printable PE (MOPE)
v • PE-PE mono film solution as a replacement of PET-PE structure
• HDPE based Printable PE suitable for rotogravure printing resists to printing
temperatures, film does not burn or loose its shape, keeps its flatness.
• Suitable for lamination process, can be laminated to another PE without any problem
• Needs optimization printing parameters on converter line (instead of PET film parameters)
• Needs optimization on packaging lines as sealing temperature, sealing time and packaging speed

Biodegradation Process • Biodegradation is a process in which the molecular structure of material is broken down through
metabolic or enzymatic processes by micro-organisms.
• Biodegradation occurs in aerobic (presence of oxygen) or anaerobic (absence of oxygen) conditions.
Biodegradable – Depend on plastics in a biologically active environment (e.g. compost). The destruction of the material happens directly through the consumption by mircrobes.

ASTM DD5511: Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High Solids Anaerobic-Digestion Conditions. Intertek India Pvt. Ltd Test Report: ASTM D5511 starts that for the test to be considered valid, the positive control (reference materials) must achieve 70% biodegradation within 30 days. The positive control (reference material) showed 71.11% biodegradation on 21st day & 94.09% on 45th day. • Suitable for landfill biodegradable • This is a “landfill biodegradable” technology, not a “Compostable” solution. • The performance is predicated on internationally recognized ASTM testing
standards (ASTM D5526 & ASTM D5511).
