Title:

POLYPROPYLENE RESIN COMPOSITION FOR METAL VAPOR- DEPOSITED FILM, FILM FOR METAL VAPOR DEPOSITION AND METAL VAPOR-DEPOSITED FILM COMPRISING THE SAME

Document Type and Number:

Japanese Patent JP2003176389

Kind Code:

A

Abstract:

To provide a metal vapor-deposited film having excellent rigidity, heat sealability, blocking resistance and surface scuff properties with a slight soluble component and excellent adhesion of a vapor-deposited film, printability on a vapor-deposited surface and laminating properties on the vapor-deposited surface and a resin composition capable of affording the film.

This metal vapor-deposited film is obtained by using a polypropylene resin composition for the metal vapor-deposited film comprising a specific antiblocking agent, a specified antioxidant and hydrotalcites in a propylene random copolymer composed of 88-99.5 mol% of propylene units, 0.5-12 mol% of ethylene and/or butene units, 115-150°C melting point, 1-30 g/10 min melt flow rate (MFR), ≤1.5 wt.% soluble content at ≤20°C measured by a cross fractionating chromatography, ≤6.0×104 weight-average molecular weight of the soluble content, ≤4.0 wt.% soluble content at ≤40°C and ≤8.0×104 weight-average molecular weight of the soluble content.
