APPEEL 53021 is a modified ethylene vinyl acetate copolymer resin designed to function as a sealing layer for lidding applications. It is most often suggested to provide strong peelable seals to polypropylene, and moderate seals to polystyrene, polyester, PVC and is available in pellet form for use in conventional extrusion or coextrusion equipment designed to process polyethylene resins.

Uses

• Lidding Sealant

• APPEEL 53021 是一种改性乙烯醋酸乙烯酯共聚物树脂，设计用作封盖应用的密封层。通常建议为聚丙烯提供牢固的可剥离密封，为聚苯乙烯、聚酯、PVC 提供中等密封，并以颗粒形式提供，用于设计用于加工聚乙烯树脂的传统挤出或共挤出设备。使用封盖密封胶
