LAMINATED FILM FOR PACKING SENSITIVE PAPER

摘要

PURPOSE:To obtain a laminated film causing no trouble in automatic packing and pulling work by laminating a high density polyethylene layer and a low density polyethylene layer in (0.5-7):1 ratio by thickness and adding a transmission preventive against light of >=100mmu to one or both of the layers. CONSTITUTION:A high density polyethylene layer with 0.94-0.97g/cm<3> density and 0.02-2g/10min melt index (MI) and a low density polyethylene layer with 0.915-0.934g/cm<3> density and 0.5-5.5g/10min MI are laminated in (0.5-7):1 ratio by thickness to form a packing film. At this time, to one or both of the layers is added a transmission preventive absorbing light of >=100mmu. A dark pigment such as carbon black and benzotriazole as a near ultraviolet absorber are combinedly used as the preventive. Thus, packing causing no trouble is enabled by means of an automatic packing machine.
