杜邦Appeel? 52004是一种改性的乙烯酸三元共聚物树脂,设计用于盖子密封层,见的密封材料是发泡聚苯乙烯。它可以是颗粒形式,用于传统的挤出或共挤设备设计加工聚乙烯树脂。采用盖面密封胶,对发泡聚苯乙烯具有良好的热密封性和易剥离性,无需底漆即可实现优异的箔材直接粘合性。Appeel? 52004符合日本卫生福利部规范20。这种盖子的典型结构是:纸/PE/箔/Appeel? 52004 Appeel? 52004用作发泡PS的盖子材料的热密封层,尤其用于方便面杯的包装。Appeel? 52004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? 52004 is a modified ethylene acid terpolymer resin designed to function as a sealing layer for lidding applications, most commonly sealing to foamed polystyrene. It is available in pellet form for use in conventional extrusion or coextrusion equipment designed to process polyethylene resins. Uses Lidding Sealant Applications Good heat sealability and easy peelability to foamed PS. Excellent direct foil adhesion without the use of primers. Appeel? 52004 conforms to Code #20 of the Ministry of Health and Welfare Japan. Typical structures for this lidding would be: Paper/PE/Foil/Appeel? 52004 Appeel? 52004 is used as a heat seal layer in lidding material for foamed PS, especially used in the packaging of instant noodle cup. Appeel? 52004 can also be used as a sealant in general flexible packaging. It provides low temperature seals for snacks and confectionery.
