Abstract: Styrene resin films having been imparted antistatic properties to both film surfaces and good adhesion properties of the films to envelope paper, and a process for producing the same. In these styrene resin films, the surface tension of the front surface of the film base differs from the surface tension of the back surface owing to a hydrophilic treatment and modifiers having almost the same compositions are applied onto the respective surfaces each in an adequate weight.

Abstract: A high-orientation multilayered film incorporates at least one cold drawn, highly oriented resin layer excellent in mechanical strength and suitable mainly for use as packaging material. Because of its specific stratal construction which is highly adaptable to afford a wide variety of specific functions, the composite film is suitable for manufacture of thermally shrinkable films which excel in transparency and in ability to shrink rapidly particularly at low temperatures. Also disclosed is a process for drawing at specific low temperatures at high expansion ratios the aforementioned multiplicity of resin layers either all by themselves or in conjunction with layers of other resins by utilizing the cold drawability of the aforementioned resin layers excelling in mechanical strength.
