VINYLIDENE CHLORIDE-BASED RESIN WRAP FILM AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vinylidene chloride-based resin wrap film that has superior adhesiveness, transparency and barrier properties, and also has physical properties superior in production adaptability.SOLUTION: A polyvinylidene chloride-based resin wrap film is obtained by the steps of: extruding a vinylidene chloride-based resin composition from a die in a melt state so as to have a pipe-like shape, and producing an extruded product having a hollow part; cooling and solidifying the extruded product in such a state that a sock solution containing 1.5-50 mass% of a surface active agent that is compatible with water and becomes a single liquid with water is stored in the hollow part; and subjecting the cooled and solidified extruded product to inflation treatment.
