CROSSLINKED HEAT-SHRINKABLE LAMINATED FILM

摘要

PURPOSE:To provide the title film excellent in transparency and film strength and also excellent in a heat shrinkage factor or heat shrinkage stress as a heat shrink pakaging film and heat sealability by making the crosslinking degree of a base layer larger than that of a surface layer. CONSTITUTION:A laminated film is formed by providing a surface layer formed from a linear low density ethylene/alpha-olefin copolymer (pref. having density of 0.910g/cm<3> or more) having density larger than that of a linear low density ethylene/alpha-olefin copolymer forming a base layer at least by 0.01g/cm<3> or more to the base layer and irradiated with ionizing radiation of 5-30Mrad and stretched under heating to obtain a crosslinked heat-shrinkable laminated film.
