ABSTRACT:
Described is a transparent shrinkable film comprising a base layer prepared from propylene-containing polymers and a hydrocarbon resin. The base layer contains about 5% to 40% by weight of a propylene homopolymer, 0% to about 30% by weight of a hydrogenated hydrocarbon resin having a softening point in the range from about 80.degree. to 125.degree. C., and about 30% to 95% by weight of a random ethylene-propylene copolymer, the percentages being related to the total weight of the mixture. A top layer is arranged on either side of the base layer. The invention also describes a process for the manufacture of the film.
