Title:

PACKAGING FILM, AND PACKAGING BODY

Document Type and Number:

Japanese Patent JP3969111

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a packaging film of excellent anti-fog property, slipping property, blocking resistance, and transparency.
SOLUTION: This packaging film is formed of at least two laminates having a biaxially-oriented base layer mainly consisting of polypropylene resin, and a heat seal layer which is formed on at least one side and mainly consisting of polyolefin resin. The surface of the heat seal layer has anti-fog property, and the heat seal layer contains organic polymer particles of the grain size of 0.1 to 7.0 μm and inert particles of the grain size of 0.1 to 7.0 μm by the amount per 100 pts.wt. of the resin to form the heat seal layer which satisfies the inequalities of 0.10≤C1/C2≤5.00 (1) and 0.15≤C1+C2≤1.00, where C1 is the amount (pts.wt.) of organic polymer particles of the grain size of 0.1 to 7.0 μm, and C2 is the amount (pts.wt.) of inert particles of the grain size of 0.1 to 7.0 μm.
