Claim 0:
1. A thermoforming process for producing a film laminate, the process comprising:
providing a compact decorative layer comprising a lacquer layer on an upper side, wherein the compact decorative layer further includes an underside;
applying a foamable layer directly on the underside of the compact decorative layer, wherein the foamable layer is based on a polymer composition comprising:
a) from 15 to 60 parts by weight of at least one thermoplastic vulcanizate (TPV), wherein the at least one TPV comprises a thermoplastic phase and a vulcanized elastomer phase;
b) from 15 to 35 parts by weight of at least one high melt strength polyolefin (HMS polyolefin);
c) from 30 to 60 parts by weight of at least one low density polyethylene (LDPE); and,
d) a chemical blowing agent;
wherein proportions of a), b), c) and d) are a total of 100 parts by weight; and
wherein the vulcanized elastomer phase of the at least one TPV serves as a phase disruptor that minimizes flow behavior of at least the HMS polyolefin and the LDPE with respect to each other;
thermoforming the film laminate, wherein the foamable layer is transformed to a foam layer, and wherein the density of the foam layer is less than 800 kg/m3; and,
crosslinking the film laminate.
