Abstract
1352439 Polypropylene laminate OJI YUKA GOSEISHI KENKYUJO KK 6 July 1971 [6 July 1970 21 Aug 1970 (2)] 31656/71 Heading B5N A process for producing a synthetic paper comprising a base layer and a paper-like layer in laminated combination comprises preparing a film of a thermoplastic resin uniaxially stretched in the longitudinal direction to constitute the base layer, the resin being essentially a mixture of an isotactic polypropylene resin and an additive which is a polymeric plasticizer and/or fine filler, which fine filler is present in an amount of from 0À2 to 8% by volume and has an average particle size of from 0À5 to 5 microns, laminating on to at least one surface of the film a second isotactic polypropylene resin containing from 0À2 to 30% by volume of a fine filler having an average particle size of from 0À5 to 30 microns blended therewith, thereby to form a composite structure, wherein the second polypropylene resin constitutes the paper-like layer; the fine filler content of the paper-like layer is greater than that of the base layer when the additive of the base layer is solely a fine filler; heat stretching the composite structure in a transverse direction perpendicular to the longitudinal direction; and cooling the structure substantially as it is maintained in its stretched state. In a preferred embodiment, the base layer is formed of a sheet composed essentially of a mixture of a first isotactic resin and a polymeric plasticizer and which has a molecular orientation in the longitudinal direction prior to stretching. The isotactic polypropylene may be a homopolymer or a copolymer of propylene with not more than 10% by weight of a comonomer, e.g. ethylene, butene-1, vinyl chloride, styrene or an acrylic acid ester. The polymeric plasticizer may be a high density homo- or co-polymer of ethylene, a low density polyethylene, a copolymer of ethylene with propylene, a vinyl ester, e.g. vinyl acetate or vinyl chloride, a homo- or copolymer of styrene or a substituted styrene, specified comonomers being acrylonitrile or a methacrylic acid ester, polyvinylchloride, a vinyl chloridevinylidene chloride copolymer and atactic polypropylene. The fine filler may be a powdered resin, clay, talc, asbestos, gypsum, barium sulphate, calcium carbonate, magnesium carbonate, titanium oxide, zinc oxide, magnesium oxide, diatomaceous earth, silicate or a mixture thereof. The paper-like layer may be bonded to the base layer by calendering or by melt-extrusion. In a preferred embodiment, an anchor coat is deposited on the base film prior to lamination.
