HEAT-SHRINKABLE HOLE-CONTAINING FILM

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable film which enables separation of a container plastic such as PET by the liquid specific gravity method without causing environmental problems and has sufficient rigidity and breakage resistance. SOLUTION: The heat-shrinkable hole-containing film having a bulk density of 0.50 to 0.99 is obtained by at least monoaxially stretching a resin composition obtained by mixing a component (A) of a lactic resin composition having a Vicat softening point of 50-95°C with a component (B) of a polyolefin resin composition which is incompatible with the above component (A) and has a storage modulus at 80°C of 0.25-2 GPa and a melt flow rate of 1.0-5.0 g/10 min at a mass ratio of (A) to (B) of 90-60:10-40.
