Mat, sealable, shrinkable, biaxially oriented polypropylene multilayer film, process for its preparation and its use

摘要

The invention relates to a heat-sealable, shrinkable, multilayered polypropylene film comprising at least one base layer containing polypropylene or a polypropylene mixture, and at least one top layer containing a mixture or blend of two components I and II. The mixture contains copolymers and terpolymers of alpha -olefins having 2 to 10 carbon atoms and HDPE. The film has a longitudinal shrinkage of 8 %//= 10 % and a transverse shrinkage of 10 %//= 10 % at 120@C/90@C. The film has a minimum heat-sealing temperature of /= 124@C. The film is matt.
