  • Patent number: 5725715
    Abstract: A squeezable tubular container (a) which is formed from a composition containing a polyethylene having a density of 0.900 to 0.975 g/cm.sup.3 and an ethylene/.alpha.-olefin copolymer having a density smaller than 0.900 g/cm.sup.3, (b) has a crosslinking caused under irradiation with electron beam, and (c) is sterilizable at a high temperature or is heat-sealable or ultrasonically sealable; and a process for the production thereof.
    Type: Grant
    Filed: July 2, 1996
    Date of Patent: March 10, 1998
    Assignees: Mitsui Petrochemical Industries, Ltd,, Yoshino Kogyosho Co., Ltd., Japan Atomic Energy Research Institute
    Inventors: Keizo Makuuchi, Fumio Yoshii, Yasuo Futami, Masanobu Ishiyama, Gen Miyamoto, Hideo Kushida, Sei Nakajima, Takahiro Kurihara, Ryoji Sugawara, Hideshi Kawachi, Mikio Nakagawa
  • Patent number: 5579913
    Abstract: Disclosed are a polypropylene resin composition comprising a crystalline polypropylene having a high stereoregularity and a terpene resin and a petroleum resin each having no polar group; a polypropylene stretched film formed from the polypropylene resin composition; and a polypropylene multi-layer stretched film having a base layer formed from the polypropylene resin composition and surface layer formed from a polypropylene type polymer. The polypropylene stretched film and a polypropylene multi-layer stretched film have excellent water-vapor barrier properties and transparency, and a high Young's modulus.
