<p>PURPOSE:To obtain the multilayered sheet extremely well-balanced in physical properties such as moistureproof characteristics, transparency, rigidity, damage resistance, impact resistance, chemical resistance or water resistance, excellent in appearance and moldability at the time of the molding processing of a film or a sheet, good in oil resistance and eliminating a problem of a stress crack due to sebum by laminating a resin layer composed of polypropylene to at least the single surface of a resin layer composed of amorphous polyolefin. CONSTITUTION:A highly moistureproof drug packing multilayered sheet is constituted by laminating a resin composed of polypropylene (B) to at least the single surface of a resin layer composed of amorphous polyolefin (A) with thermal deformation temp. of 100 deg.C or lower.</p> |
