Publication number: 20020187333Abstract: The present invention provides a process for effectively extruding a polypropylene polymer onto a cellulosic substrate. In the process, a polypropylene polymer is co-extruded with a polyolefin polymer other than polypropylene so as to stabilize the molten polypropylene polymer layer. Co-extrusion also allows extruding the polypropylene polymer at elevated temperatures so that the polypropylene is oxidized. Thus the polypropylene layer more readily bonds to a substrate without requiring a primer or ozone pretreatment step.Type: ApplicationFiled: May 23, 2001Publication date: December 12, 2002Inventor: Jiren Gu

Publication number: 20020182429Abstract: A decorative sheet using a paper substrate is provided which, even in the case of the adoption of a construction such that a surface resin layer has been formed by crosslinking through an ionizing radiation irradiation to improve surface properties such as abrasion resistance, does not cause an unfavorable phenomenon such that the workability is lowered due to a deterioration in strength of the paper substrate caused by the ionizing radiation and, consequently, the sheet is broken at the time of lamination. A decorative sheet S comprises, stacked in the following order from the top surface toward the back surface, a surface resin layer 4 formed of a crosslinked product of an ionizing radiation-curable resin, a paper substrate 1, and a high-modulus resin layer 2 having a tensile strength of not less than 40 MPa as measured according to JIS K 6301. A pattern layer 3 or the like may be additionally provided. The use of a needle-leaved tree pulp as the paper substrate is preferred from the viewpoint of strength.Type: ApplicationFiled: July 17, 2001Publication date: December 5, 2002Inventors: Eiichirou Yokochi, Hajime Takeuchi

Publication number: 20020160216Abstract: A paper-plastic laminate sheeting capable of being converted by conventional equipment into envelopes, grocery bags and other dilatable container products that initially are in a flat state and are normally made of paper. The sheeting is composed of a paper facing sheet cold-laminated by means of a water-based adhesive to a reinforcing film of synthetic plastic material, such as polypropylene. The film is oriented to impart exceptional tear and burst strength characteristics to the resultant waterproof product. The product, whose exterior surface is formed by the paper facing sheet, is readily printable. For some applications, a second paper facing sheet is cold-laminated to the other side of the film to produce a three-ply laminate sheeting whose exposed surfaces are readily printable and can accept conventional adhesives.Type: ApplicationFiled: June 10, 2002Publication date: October 31, 2002Inventors: Arnold B. Finestone, Gilbert Bloch

Publication number: 20020155279Abstract: A method for manufacturing a dimensionally stable composite cellulosic product having side and edge surfaces involves applying a sheet of thermoplastic material to at least one side surface of the composite product. Pressure and heat are applied for a pre-determined period via a heated press to melt the thermoplastic material to bond to and coat the at least one side surface of the product. The resulting product enjoys significantly improved dimensionally stability when exposed to water. Thickness swelling of the coated product is reduced by over 70% as compared to a conventional composite cellulosic product without the coating. In the case of oriented strand board (OSB) manufactured according to the method of the present invention, thickness swell of 2-5% after 24 hour water soaking is observed as compared to 10-15% swell with conventional OSB.Type: ApplicationFiled: February 14, 2001Publication date: October 24, 2002Inventors: Chunping Dai, Peter Ens
