Abstract
PURPOSE:To obtain a packaging material for an inexpensive photosensitive substance having large physical strength (tensile strength, a tearing strength, burst strength, etc.) and excellent heat sheeting property by so laminating two multilayer coextruded obliquely uniaxially oriented films having predetermined 2 layers as to cross molecule orientation axis. CONSTITUTION:Two multilayer coextruded obliquely uniaxially molecular oriented films having a high density polyethylene resin film layer containing at least 50wt.% of high density polyethylene resin of 0.941g/cm<3> or more of density, and 1-0.7g/10min of melt index, and a straight chain low density polyethylene resin film layer containing at least 30wt.% of straight chain low density polyethylene resin of 0.940g/cm<3> or less of density, 0.5-30g/10min of melt index are so laminated as to cross a molecule orientation axis to each other, and at least one layer having light screening ability is provided. The screening layer may employ an HDPE resin film layer, an L-LDPE resin film layer, an adhesive layer, or in case of laminating, an intermediate layer, or a flexible sheet layer. In order to provide the light screening ability, a metal foil is used, or a thin metal film is formed, or a light screening substance is added.
