摘要:
The present invention relates to a thermoformable, multilayer, co-extruded adhesive-free and EVOH-free film containing polyamide, polyolefins, and/or copolymers based on olefins. This film is particularly suitable for the packaging of products that have been subjected to a heat treatment in thermoformed films. The films are characterised by an outer layer of polyamide and a second outer layer of polyolefins or coploymers based on olefins, wherein the film composite does not delaminate even at temperatures between 50null C. and 150null C.

摘要:
Film of at least two layers having at least one side softening at a lower temperature and at least one side softening at a higher temperature, wherein the higher-softening side substantially consists of a thermoplastic polyurethane which softens at above 100.degree. C. on a Kofler hot bench and the median of the softening range is at least 15.degree. C. above that of the lower-softening layer and the matrix component of the lower-softening side consists of at least one hot-bonding thermoplastic material from the group comprising polyamides, polyesters and polyurethanes having a median of the softening range on a Kofler hot bench of below 100.degree. C. and at least one thermoplastic additive component containing hydrocarbon is added to the lower-softening layer.
