摘要： A laminated film which comprises an uniaxially molecular oriented thermoplastic resin film layer containing 0.3 to 30 wt. % of white inorganic particles having a mean particle size of 0.01 to 50 .mu.m, an ethylene copolymer resin film layer containing more than 10 wt. % of ethylene copolymer resin, a substance having antiblocking action and an antioxidant and having a melting point of lower than said uniaxially molecular oriented thermoplastic resin film layer, and a metallized thermoplastic resin film layer interposed between said uniaxially molecular oriented thermoplastic resin film layer and said ethylene copolymer resin film layer.The laminated film of the invention hardly curls, and it is excellent in tear strength and heat sealing properties. Moreover, when the package is severely shaken during transportation, moistureproofness and lint-free ability can be still secured. Besides, the uniaxially molecular oriented thermoplastic resin film layer is made a pearl-like color bringing a favorable appearance, and is excellent in color printability other than white silver colors.
