PURPOSE:To obtain a film having excellent transparency, by using a styrene modified polyolefin resin and adjusting the drawing temp. of this film. CONSTITUTION:A laminate composed of a surface layer film prepared of styrene modified polyolefine resin particles as a base material obtained by polymerizing styrene monomer by heating an aqueous suspension containing 100 pts. wt. polyolefine resin particles, 50-400 pts. wt. styrene monomer and 0.01-1 pts. wt. radical polymerization initiator based on 100 pts. wt. styrene monomer and a base layer film prepared of a resin whose m.p. is 15 deg.C or more higher than that of this styrene modified polyolefine resin, is drawn at least in one direction at a temp. which is lower than the m.p. of the resin constituting the base layer and the m.p. of the styrene modified polyolefine resin or above the m.p. to obtain a transparent drawn film. This film can be printed by means of not only a gravure printing for polyolefine but a gravure printing tor cellulose film. The degree of opaqueness of this film is 10% or lower and it is suitable for packaging film. |
