摘要： A shrink film is provided which is superior in glossiness, mechanical strength, and rigidity, and which is also provided with a property of preventing natural shrinkage. The shrink film with excellent properties is produced by using a resin composition which is obtained by graft polymerization of copolymers of styrene and butadiene with styrene, methylmethacrylate, and butylacrylate. The thus obtained resin composition is extruded after melting and kneading, and drawn into a film in two directions, and exposed at a temperature within a temperature range for the thermal setting so as to obtain the orientation according to ASTM D1504 of the shrink film in range of 1.5 to 5.0 MPa.
