Abstract

PURPOSE: The title material, usable well in antomatic packaging, having improved heat sealability, obtained by laminating (A) a polyolefin film layer on (B) a blended layer of a (co)polymer prepared from a specific ethylenic unsaturated monomer and an atactic polyolefin.
CONSTITUTION: A) A film layer, consisting of a) a polymer selected from the group consisting of polypropylene, polybutene, and poly 4-methylpentene, b) a copolymer having not less than 95 wt.% of component units similar to that of the ingredient a), or c) the blend of a) and b), is laminated on B) a layer consisting of d) 95W40 wt.% of a (co)polymer prepared by (co)polymerizing one or more monomers having a 3W10C ethylenic unsaturated group and (e) 5W60 wt.% of an atactic polyolefin to give the desired material.
