<p>PURPOSE:To obtain an opaque stretched molded product having pearl like gloss and not losing an opaque feeling even at the time of sealing by laminating a molded article obtained from a low m.p. crystalline propylene copolymer having a crystal m.p. 10 deg.C or more lower than that of a crystalline polypropylene resin to at least the single surface of a stretched molded article. CONSTITUTION:A molded article is obtained using a composition prepared by compounding 3-30 wt.% of a cyclopentadiene type petroleum resin having a softening point (ring and ball method) of 160 deg.C or higher with a crystalline polypropylene type resin and, to at least the single surface of this molded article, a molded article obtained using a low m.p. crystalline propylene type copolymer having a crystal m.p. 1.0 deg.C or more lower than that of the crystalline polypropylend type resin is laminated. Subsequently, this laminate is stretched twice or more at least in one direction within a temp. range from the crystal m.p. of the crystalline polypropylene type resin to the softening point of the cyclopentadiene type resin to obtain a desired opaque laminated stretched molded product.</p> |
