Abstract: A method of manufacturing thermoplastic flexible transparent PVC film (sheet) without flow marks and air pit is capably provided with high efficient production to upgrade the quality of plastic film (sheet), which is included the following steps: calendering melted plastic material by calenders into melting plastic film (sheet) with predetermined thickness, quickly chilling and setting the melting plastic film (sheet) with chilling water, removing water from the cooled plastic film, heating the plastic film to dry out any residual water and controlling the plastic film again to a temperature from 30° C. to 85° C., and applying a pressure ranging from 1 kg/cm2 to 8 kg/cm2 on the plastic film (sheet) while winding it into a roll. Plastic film (sheet) produced with this method has good transparency and smooth surface without flow mark and air pit.

Abstract: The present invention is a process and its product by embossing or processing the transparent soft or solid thermoplastic polyvinyl chloride(PVC) sheet, the thermoplastic polyethylene(PE) film sheet, the ethylenevinyl acetate copolymer(EVA) film sheet, and the PEVA(the mixture) film sheet; and more particularly a product by utilizing said thermoplastic material plastic sheet printed by lithographic or gravure printing; whereon a pattern arranged by a computer is printed. The plastic sheet is further embossed by a embossing machine on both front and rear sides to produce a coordinated indension so as to produce a product with a stereo flash effect.
