杜邦?Appeel? 53021是一种改性乙烯-乙酸乙烯酯共聚物树脂,设计用于盖子密封层。通常建议为聚丙烯提供牢固的可剥离密封件,为聚苯乙烯、聚酯、聚氯乙烯提供适度的密封件,并以颗粒形式提供,用于传统挤出或共挤设备,用于加工聚乙烯树脂。低温热封。Appeel? 53021提供低温热密封,在90℃时具有足够的密封强度。各种材料的热密封性,包括聚乙烯、聚丙烯、聚苯乙烯和硬质聚氯乙烯。Appeel? 53021还可以封纸、纸板、机织物、无纺布、木版纸和相纸。Appeel? 53021允许从大多数塑料材料(不包括PE)剥离密封。高透明度。Appeel? 53021符合日本卫生福利部规范20。Appeel? 53021用作注塑和真空注塑塑料容器盖材料的热密封层,尤其是用于酸奶、果酱、黄油和其他食品包装的HIPS和PS。这种盖子的典型结构为:OPP/PE/Appeel? 53021 PET/PE/Appeel? 53021,在漆面/印刷/箔/PE/Appeel? 53021纸/PE/箔/PE/Appeel? 53021上,Appeel? 53021也可用作一般软包装中的密封剂。它为零食和糖果提供低温密封。 DuPont? 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. Low temperature heat seal. Appeel? 53021 offers low temperature heat seals with adequate seal strength at 90oC. Heat sealability to various materials including PE, PP, PS, and Rigid PVC. Appeel? 53021 can also be sealed to paper, paperboard, woven fabrics, non-woven fabrics, wood and photographic papers. Appeel? 53021 allows a peelable seal from most plastic materials excluding PE. High transparency. Appeel? 53021 conforms to Code #20 of the Ministry of Health and Welfare Japan. Appeel? 53021 is used as a heat seal layer in lidding material for injection molded and vacuum molded plastic containers, especially HIPS and PS used in the packaging of yogurts, jams, butter and other food items. Typical structures for this lidding would be: OPP/PE/ Appeel? 53021 PET/PE/ Appeel? 53021 Over lacquer/Print/Foil/PE/ Appeel? 53021 Paper/PE/Foil/PE/ Appeel? 53021 Appeel? 53021 can also be used as a sealant in general flexible packaging. It provides low temperature seals for snacks and confectionery.
