<p><P>PROBLEM TO BE SOLVED: To provide a heat shrinkable film which is excellent in strength, abrasion resistance, solvent resistance, dimensional stability, and transparency, demonstrates high shrinkability and flexibility by heating, can obtain a beautiful finish, and is excellent in recycling aptitude after being used. <P>SOLUTION: The heat shrinkable film 1 has an intermediate layer 2 of an olefin resin containing an ethylene-propylene-butene ternary copolymer and outside surface layers 3 of a polyester resin arranged on both sides of the intermediate layer 2. The interlayer adhesive strength between the intermediate layer 2 and the outside surface layer 3 is at least 3.0 N/15 mm. The content of the ethylene-propylene-butene ternary copolymer of the intermediate layer 2 can be 45 wt.% or above. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
