产品说明
Appeel® 20D784 is a modified ethylene acrylate resin designed to function as a sealing layer for lidding applications. It is most often suggested to provide peelable seals over a broad temperature range to a number of container materials including PP, PS, and some PVC types. Appeel® 20D784 is available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene resins.
