Abstract

PURPOSE: To obtain a film having improved barrier properties to oxygen and steam, by applying a solution obtained by dissolving a copolymer resin of the vinylidene chloride type in a specific mixed solvent to a film.
CONSTITUTION: At least one side of a film (preferably biaxially oriented polypropylene film) is covered with a coating solution obtained by dissolving preferably 10W30wt% vinylidene chloride type copolymer resin (e.g., vinylidene chloride- vinyl chloride copolymer, etc.) in a mixed solvent comprising (A) tetrahydrofuran, (B) toluene and (C) a poor solvent (e.g., acetone, etc.) in weight ratios A/B= 50W80/50W20, (A+B)/C=50W85/50W15, and it is dried. The thickness of coating layer is preferably 2W5μ.
