Patent ID: 7829633

Claim:
A process for producing a packaging comprising a thermoformed film comprising thermoplastic olefins comprising thermoforming a thermoformable film at a temperature in the range from 70 to 170° C., wherein said thermoformable film is a monofilm or a multilayer film, wherein said monofilm or at least one layer of said multilayer film comprises from 20 to 80% by weight, based on the total weight of said thermoplastic polyolefins, of at least one COC having a glass transition temperature Tg in the range from 65 to 200° C., as measured to DIN EN ISO 11357-1 with the aid of a DSC at a heating rate of 10 K/min, wherein said thermoformed film has an improved heat distortion temperature and a high water-vapor barrier, and wherein the heat distortion temperature of said packaging is in the range of from 60 to 200° C.
