发明名称 DEEP-DRAWING, THERMALLY WELDABLE AT LEAST THREE-LAYER POLYAMIDE AND POLYOLEFINS BASED FOIL FROM A RECYCLING PROCESS, CONTAINING HIGH PROPORTION OF RECYCLATE AND METHOD OF OBTAINING SUCH FOIL
摘要 The present invention relates to multilayered, heat-sealable, recycled film comprising at least one scrap layer, a heat-sealable layer and an accompanying layer which is arranged either between the scrap layer and the heat-sealable layer or on the outside on the side facing away from the heat-sealable layer, where - the film is thermoformable, - the scrap layer comprises polyamide (nylon)/polyolefin recyclate and an adhesion promoter, where the recyclate content in the scrap layer is from 60 to 98% by weight and the adhesion-promoter content is from 2 to 40% by weight, - the recyclate has a polyamide content of from 3 to 45% by weight, and - the heat-sealable layer has a single- or multilayer structure and comprises polyolefinic polymer or copolymer, where the layers can be identical or different, - the accompanying layer comprises polyamide, polyolefin, EVOH and/or adhesion promoter or an adhesion-promoter mixture
