Multilayered plastics film and process for its production
Abstract
Abstract The invention provides a multilayer plastics film comprising at least two film layers, one of which has a thickness of 10 to 50 mu m and a softening point of 140 DEG to 200 DEG C., and the other of which has a thickness of 10 to 50 mu m, a softening point of 70 DEG to 130 DEG C. and initial melting point of from 100 DEG to 190 DEG C., there being a temperature difference of from 30 DEG to 60 DEG C. between the softening point and initial melting point of the latter film. The invention also provides processes for making such multilayer plastics films and their use for applying to articles, particularly foamed plastics, a firmly adhering skin.
