FOOD PACKAGING FILM

摘要

PROBLEM TO BE SOLVED: To provide a food packaging film highly well balanced in heat resistance, cutting properties, adhesion, winding peelability and the like. SOLUTION: The food packaging film comprising at least five layers is constituted by laminating adhesive layers, each of which is formed from an adhesive layer resin composition, on both upper and under surfaces of an intermediate layer formed from a 4-methyl-1-pentene polymer and further laminating outer layers, each of which is formed from an outer layer resin composition, on the surfaces of the respective adhesive layers. The contains 50-85 wt% of high-pressure low density polyethylene with a density of 0.915-0.935 g/cm3and 50-15 wt% of a 1-butene polymer and contains 85-99 wt% of high-pressure low density polyethylene with a density of 0.915-0.935 g/cm3, 0.5-5 wt% of an anti-fogging agent and 0.5-1.0 wt% of a tackfier.
