Abstract

Process for the production of a heat-shrinkable laminate, which has a low oxygen permeability, characterized in that it comprises the steps of (1) extruding a film (A) of a plasticized vinylidene chloride polymer; (2) stretching said film; and (3) before or after said stretching, laminate each side of said film to polymeric strains (B1 and B2) that (a) will absorb the plasticizer of the vinylidene chloride polymer and (b) have a combined thickness at least 75% of the thickness of the vinylidene chloride polymer film.
