Abstract

The invention relates to a multilayer, readily thermoformable film, having the sequence arrangement ABCD, in particular for packaging objects with sharp edges, where - the sequence A comprises at least one copolyamide based on caprolactam and/or a mixture of an aliphatic polyamide with copolyamide based on caprolactam, and/or amorphous polyamide, - the sequence B contains at least one layer of olefinic (co)polymers, - the sequence C contains at least one layer of copolyamide based on caprolactam and/or a mixture of an aliphatic polyamide with a copolyamide based on caprolactam, and/or an aromatic polyamide, and the C:A thickness ratio is from 1.5 to 4, - the sequence D contains at least one layer of olefinic (co)polymers which, as outer layer, comprises a heat-sealable material, and the thicknesses are in the D:B ratio of from 3 to 10, preferably from 4 to 7.
