PURPOSE:To improve toughness, heat insulation and anti-fogging properties by incorporating an main ingredients linear ethylene-alpha-olefin copolymer in an outer layer of a laminated film, ethylene-vinyl acetate copolymer in an inner layer, and limited quantities of inorganic compound and anti-fogging agent in the laminated film. CONSTITUTION:The outer layer of a laminated film is composed of 0.5-5 pts.wt. of inorganic compound and 100 pts.wt. of polyethylene resin containing as a main ingredient linear ethylene-alpha-olefin copolymer. The inner layer is composed of 1-10 pts.wt. of inorganic compound and 0.5-3 pts.wt. of anti- fogging agent and 100 pts.wt. of polyethylene resin containing as a main ingredient ethylene-vinyl acetate copolymer. The compound mixed in the inner and outer layers is made of at least one selected from a group consisting of silicon oxide, talc, zeolite and hydrosulfites containing silicon oxide, and the ratio of the mixture of the inner layer to the outer layer ranges 2-7. |
