Abstract

PURPOSE:To prevent heat-bonding to a packaging film and a surface slip, by constituting a multilayer shrinkable film with a polyethylene layer and a polypropylene layer which are inflation-molded by a specified expansion ratio. CONSTITUTION:A multilayer shrinkable film is made of a polyethylene layer and a polypropylene layer which are inflation-molded by an expansion ratio of 2.5- 7. A polypropylene containing a liquid polybutene of molecular weight 400- 3,000 in an amount of 5-20wt% based on a weight of the polypropylene is used as the polypropylene layer. A polyethylene is a mixture of a high density polyethylene and a low density polyethylene and is composed of 60-80wt% of a high density polyethylene of melt index 0.01-0.09 and 40-20wt% of a low density polyethylene of melt index 0.1-0.7.
