Document Type and Number:
Japanese Patent JP3764109
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a body warmer packaging film using a polypropylene laminated film improved in both capacities of oxygen gas barrier properties and steam barrier properties while keeping the excellent characteristics of a polypropylene film.
SOLUTION: In the body warmer packaging film comprising a gas barrier layer (B) on a substrate material film (A), the substrate material film (A) is at least a two-layered biaxially stretched polypropylene film having a core layer (A1) containing 80-97 wt.% of crystalline polypropylene and 20-3 wt.% of at least either petroleum resin or a terpene resin and the skin layer (A2) containing copolymerization type polypropylene on the single surface of the core layer (A1).
