Document Type and Number:
WIPO Patent Application WO/2005/056292
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a heat shrink film that when used as a label of beverage container, enhances the smoothness of external surface side to thereby prevent merchandise jamming in an automatic vending machine of beverage and that is fully satisfactory in solvent bonding capability and excels in processability. [MEANS FOR SOLVING PROBLEMS] There is provided a heat shrink polyester film characterized in that (A) at least one major surface thereof is overlaid with 0.002 to 0.5 g/m2, in terms of solid content coating amount, of a silicone containing easily sliding layer, (B) the easily sliding layer having an inter-easily sliding layer frictional coefficient μd ≤ 0.27, and that (C) the heat shrink polyester film exhibits a heat shrinkage factor, as measured in the direction of maximum shrinkage after immersion in 95&ring C water for 10 sec, of 50% or greater. Thus, there is provided the heat shrink film that when used as a label of beverage container, enhances the smoothness of external surface side to thereby prevent merchandise jamming in an automatic vending machine of beverage and that is fully satisfactory in solvent bonding capability and excels in processability.
