PURPOSE:To obtain a film for a shrink label which is excellent in close fast adhesion to a container in shrink packaging and can sufficiently withstand high temperature pasteurization treatment. CONSTITUTION:A resin composition wherein principal components are 80-30wt.% of crystalline propylene.-ethylene random copolymer of 140-160 deg.C in melting point, 10-60wt.% of propylene monopolymer of M11-10, and 2-15wt.% of petroleum resin of 115-140 deg.C in softening temperature, and a main peak of a crystal fusion curve by DSC is 150-160 deg.C, is fusion extruded and quickly cooled to obtain an actually non-oriented raw film. The raw film is streched 3.0-7.0 times uniaxially within a temperature range of 100-140 deg.C. |
