杜邦A(yù)ppeel? 52004是一種改性的乙烯酸三元共聚物樹脂,設(shè)計(jì)用于蓋子密封層,見的密封材料是發(fā)泡聚苯乙烯。它可以是顆粒形式,用于傳統(tǒng)的擠出或共擠設(shè)備設(shè)計(jì)加工聚乙烯樹脂。采用蓋面密封膠,對(duì)發(fā)泡聚苯乙烯具有良好的熱密封性和易剝離性,無需底漆即可實(shí)現(xiàn)優(yōu)異的箔材直接粘合性。Appeel? 52004符合日本衛(wèi)生福利部規(guī)范20。這種蓋子的典型結(jié)構(gòu)是:紙/PE/箔/Appeel? 52004 Appeel? 52004用作發(fā)泡PS的蓋子材料的熱密封層,尤其用于方便面杯的包裝。Appeel? 52004也可用作一般軟包裝中的密封劑。它為零食和糖果提供低溫密封。 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.
