LAMINATED FILM FOR STRETCH-SHRINK LABEL AND STRETCH- SHRINK LABEL

摘要

PROBLEM TO BE SOLVED: To obtain a laminated film for a stretch-shrink label excellent in blocking resistance and holding high restoring properties after heat shrinkage. SOLUTION: A laminated film for a stretch-shrink label is constituted of a core layer comprising linear low density polyethylene with a density of 0.880-0.907 g/cm3 and a Vicat softening point of 58-88 deg.C and the outer layers, which comprise linear low density polyethylene with a density of 0.91-0.925 g/cm3 and a Vicat softening point of 90-115 deg.C, laminated to both surfaces of the core layer and the thickness of the core layer is 70-95% of the total thickness and stretching treatment is applied to the laminated film. The heat shrinkage factor of the laminated film in one direction X after the laminated film is immersed in hot water at 80 deg.C for 10 sea is 25% or more.
