Abstract

The present invention relates to multilayered, heat-sealable, recycled film comprising at least one scrap layer and a 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, - 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.
