The melt index (MI) is 0.5 g /
If the amount is less than 10 minutes, the melt moldability decreases when a large amount of a filler is blended. If the amount exceeds 50 g / 10 minutes, the melt tension decreases, which is not preferable.

The ethylene-vinyl acetate copolymer (B) used in the present invention has a vinyl acetate content of 45 to 65% by weight (preferably 50 to 65% by weight) and a melt index (MI) of 0.05 to 65% by weight. 250 g / 10 minutes (190
° C, 2160 g load) (preferably 0.05 to 150 g)

When the vinyl acetate content is less than 45% by weight or more than 65% by weight, the flexibility at the time of molding is poor. If the melt index (MI) is less than 0.05 g / 10 minutes, the fluidity at the time of melting decreases, and the moldability deteriorates. If the melt index (MI) exceeds 250 g / 10 minutes, the melt tension decreases.

If the acetonitrile-soluble component or the weight-average molecular weight or the insoluble component in benzene is out of the above-mentioned range, contamination of the molding machine occurs during mixing or molding, and
The peelability is reduced and the gloss of the molded product is reduced.

The method for producing the ethylene-vinyl acetate copolymer (B) is not particularly limited. For example, vinyl acetate and ethylene, or a small amount of an ethylenically unsaturated monomer copolymerizable therewith may be used. After obtaining an aqueous dispersion or solution by suspension polymerization, emulsion polymerization, solution polymerization method, drying, salting out and any other method such as ethylene-
A vinyl acetate copolymer (B) is obtained. The obtained ethylene-vinyl acetate copolymer (B) is dried by standing with hot air, or continuously dried by an extruder or the like to form a block or pellet, or a mixture of inorganic fine particles and higher fatty acid metal salt fine particles.
