杜邦?Appeel? 53021是一種改性乙烯-乙酸乙烯酯共聚物樹脂,設計用于蓋子密封層。通常建議為聚丙烯提供牢固的可剝離密封件,為聚苯乙烯、聚酯、聚氯乙烯提供適度的密封件,并以顆粒形式提供,用于傳統(tǒng)擠出或共擠設備,用于加工聚乙烯樹脂。低溫熱封。Appeel? 53021提供低溫熱密封,在90℃時具有足夠的密封強度。各種材料的熱密封性,包括聚乙烯、聚丙烯、聚苯乙烯和硬質聚氯乙烯。Appeel? 53021還可以封紙、紙板、機織物、無紡布、木版紙和相紙。Appeel? 53021允許從大多數(shù)塑料材料(不包括PE)剝離密封。高透明度。Appeel? 53021符合日本衛(wèi)生福利部規(guī)范20。Appeel? 53021用作注塑和真空注塑塑料容器蓋材料的熱密封層,尤其是用于酸奶、果醬、黃油和其他食品包裝的HIPS和PS。這種蓋子的典型結構為:OPP/PE/Appeel? 53021 PET/PE/Appeel? 53021,在漆面/印刷/箔/PE/Appeel? 53021紙/PE/箔/PE/Appeel? 53021上,Appeel? 53021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? 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.
