摘要:
The present invention is related to a peelable film to be sealed on a polyester-based substrate comprising a coextruded multilayer structure comprising: - a rupturable polyester-based sealant layer; - an adhesive layer in contact with said rupturable layer, comprising a polymer selected from the group consisting of ionomers, maleic anhydride grafted polyolefin, EVA, EBA, EMA and EAA; - a gas-barrier layer in contact with said adhesive layer, comprising a gas-barrier polymer selected from the group consisting of EVOH and polyamide, characterised in that the average peel strength between the adhesive layer and the rupturable sealant layer is lower than 15N/15 mm, preferably lower than 13N/15 mm as measured in a 180° peel geometry.
摘要(中):
本发明涉及一种待密封在基于聚酯的基材上的可剥离膜,该可剥离膜包括共挤出的多层结构,其包括: - 可破裂的聚酯基密封剂层; - 与所述可破裂层接触的粘合剂层,包括选自离聚物,马来酸酐接枝聚烯烃,EVA,EBA,EMA和EAA的聚合物; - 与所述粘合剂层接触的阻气层,包括选自EVOH和聚酰胺的气体阻隔聚合物,其特征在于,所述粘合剂层和所述可破裂密封剂层之间的平均剥离强度低于15N / 在180°剥离几何形状中测得的15mm,优选低于13N / 15mm。
