HEAT SHRINKABLE FILM

摘要

PROBLEM TO BE SOLVED: To provide a heat shrinkable film which has low natural shrinkability though shrinkage is initiated at a low temperature and which has biodegradability. SOLUTION: The heat shrinkable film has as a main component a polylactic acid-based polymer and is stretched at least in one direction, and this shrinkable film has a shrinkage-starting temperature within the range of 50-63 deg.C and shrinkage of >=10% when immersed in warm water having 65 deg.C for 10 seconds.
