Cesa™ Anti-Block Slip LS Additives for low-temperature sealing layers in flexible polyolefin packaging FOOD PACKAGING IN A CHANGING MARKET In many food contact applications, flexible plastic packaging is replacing rigid packaging for varied reasons; it has lightweight characteristics, is easy to customize in any shape, and has a favorable carbon footprint. With its ability to simplify packaging structures and reduce waste, Cesa Anti-Block Slip LS supports the transition from difficult-to-recycle multi-material packaging to mono-material compositions, contributing to a positive brand image in the market. KEY FEATURES • Enables the transition from complex, multi- material flexible packaging to recyclable mono- material solutions • Provides anti-block and slip functionalities for low-temperature sealing layers • Helps to eliminate non-compatible film layers in food packaging • Improves yield during sorting and enhances post-consumer recyclate (PCR) quality, helping to reduce waste • Compatible with polyolefins and seamlessly integrates into existing film extrusion processes MARKETS & APPLICATIONS Cesa Anti-Block Slip LS is used in various applications in flexible polyolefin food packaging, including bags and pouches, lidding films, and lamination films.

Cesa WithStand solutions include technical assistance to customize the additive dosage, as well as support with processes and specifications, helping to reduce time to market and saving time and cost in the development process. PRODUCT BULLETIN KEY CHARACTERISTICS • Additives to retard microbe growth in finished plastic parts, enhancing product performance • Reduces bacterial, mold and fungal growth on the surface as well as through the thickness of the plastic part • Helps reduce odor, staining, discoloration and loss of mechanical properties • Available for a variety of processes including extrusion, injection molding, blow molding, rotational molding and thermoforming MARKETS AND APPLICATIONS Suitable for a wide variety of applications, Cesa WithStand Antimicrobial Additives add value across these key markets: • Packaging* • Cosmetics • Wellness • Appliances • Electronics • Building & construction • Transportation • Wire & cable * Contact an Avient representative to check food contact compliance 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.

This, in turn, creates issues for convertors and brands who need to achieve consistent product quality across product lines, regions and markets. Lightest colored recycled materials are therefore in high demand for all applications, limiting market availability. KEY CHARACTERISTICS • Helps transition to high levels of PCR • Facilitates transfer from one PCR to another • Considers mixed grades of PCR • Works with transparent, translucent and opaque colors • Globally available with local expertise MARKETS & APPLICATIONS • Recycled PET and polyolefins • Packaging and consumer products • Injection molding • EBM (monolayer bottles) 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.
