Abstract

PURPOSE:To enable the production of a sheet or film having a uniform thickness, by performing a monoaxial preliminary stretching before biaxial-stretching them by a tubular stretching method. CONSTITUTION:10-85 Percent of inorganic fillers having a grain diameter of 0.1- 100mu, such as calcium carbonate, many types of clays, cement, asbesto, silca, metallic powder, is added to a thermoplastic resin consisting of an olefine single polymer, a copolymer of an olefine and a copolymerizable monomer, a polyolefine resin comprising mixture, a polyvinyl chloride resin, a polyester resin, a polyamid resin, etc., the mixtue being extruded through a toroidal die 1 by air inflation method. A sheet A cooled by a cooling mandrel is formed flat by means of a winding roll 3, the heated sheet 4 being monoaxial preliminary stretched by 1.3-4.0- fold in the longitudinal direction. After the sheet so processed is biaxial-stretched in a transverse and longitudinal directions so that a stretched area is increased by 30-fold or less, the sheet is cooled rapidly.
