<p>PURPOSE: To obtain a transparent highly moistureproof laminated sheet excellent in gas barrier properties of oxygen or the like by laminating an amorphous polyolefin resin layer having specific heat deformation temp., a polypropylene resin layer and a saponified ethylene/vinyl acetate copolymer resin layer in specific order. CONSTITUTION: A transparent highly moistureproof laminated sheet for packing a drug excellent in appearance, transparency, moldability, moistureproofness, oxygen gas barrier properties, impact resistance or the like is formed by laminating an amorphous polyolefin resin layer A with heat deformation temp. of 100 deg.C or lower, a polypropylene resin layer B and a saponified ethylene/vinyl acetate copolymer resin layer C in the order of B/CA/C/B or B/A/C/B. The amorphous polyolefin resin layer A is composed of a copolymer of an adduct reaction product of cyclopentadiene or a derivative thereof and an unsaturated monomer such as ethylene or butadiene or a hydrogenated substance thereof.</p> |
