In this context PET’s enhanced recyclability and the capability to reintroduce post-consumer recycled (PCR) content into new food packaging make it an attractive choice for brands and converters worldwide. By extending the use of APET to higher- temperature applications above 60°C, brand owners can access better options that align with their sustainability goals.

For manufacturers, designers and brand owners, this innovative system redefines the process of color development, elevating it to a new level of DIY efficiency. Typically used within extrusion, injection molding and blow molding processes with specific benefits for: • Manufacturers – Take control of your color supply • Brand Owners – Efficient online color management • Designers – Rapid visualization of your color www.avient.com Copyright © 2020, Avient Corporation.

Adding an anti-fog solution to film delivers value to brand owners and film manufacturers in multiple ways: Reduce operating cost: Anti-fog plus additives are a drop-in solution. Increase brand image: Anti-fog plus additives enhance the appeal and attractiveness of food packaging.

This, in turn, creates issues for convertors and brands who need to achieve consistent product quality across product lines, regions and markets. Convertors and brand owners need to make educated choices for their recycled materials based on formulation expertise and data science to help achieve a consistent packaging product.

Brands and converters are increasing their use of rPET in packaging to meet current regulations or their own sustainability commitments, but quality rPET is needed. Capture maintains PET clarity and allows up to 100% rPET usage to help brands achieve their goals.

OnColor IR Sortable Black is available in a range of blacks, and can also be customized to support the needs of brand owners, allowing black packaging to remain an option for current products. KEY CHARACTERISTICS • Infrared sortable black color palette available • Customized sortable black upon request • Solid or liquid form • Resins: PET & polyolefins • Processes: extrusion, injection, thermoforming APPLICATIONS OnColor IR Sortable Black can benefit the following stakeholders operating within the food and beverage packaging industry: • Retailers • Brand Owners • Converters • Recycling Facilities • Packaging Recovery Organizations PRODUCT BULLETIN OnColor™ IR Sortable Black Collection Ultramarine Obsidian BK Onyx BK Jasper BK BK Panther Iris Blossom Moonlit BK Gotland BK www.avient.com Copyright © 2020, Avient Corporation.

Due to its excellent circular properties, Amosorb Oxyloop-1 can contribute favorably to the buildup of rPET feedstock that will be available in the market, which is desirable to both recyclers and brands. RECYCLABILITY & rPET Brand owners wishing to operate within a circular economy want to incorporate higher levels of rPET into their packaging.
