A transparent, shrinkable film composed of at least one layer which is a mixture of 85-10 weight percent of a linear polyamide, linear copolyamide, or an elastomeric component, and 15-90 weight percent of a partially aromatic polyamide or partially aromatic copolyamide. The films of the present invention can be shrunken at economically feasible temperatures, shrink in such a way so as not to damage the goods encased therein and also possess desirable transparency and gas permeability properties.
