(57) [Summary] [PROBLEMS] A rubber-modified polystyrene resin composition, Providing a film with excellent printing accuracy and less thickness unevenness while maintaining excellent transparency, tensile strength and elongation. SOLUTION: When the film is immersed in a silicon oil bath at 120 ° C. for 3 minutes, the MD heat shrinkage is 0 to 60. %, The TD heat shrinkage ratio is -2 to 5%, the average gel particle diameter is 0.1 to 1 µm, the gel amount is more than 10% by weight and 30% by weight or less, and the methanol-soluble content is 0.5 to 5%. A film characterized by being a rubber-modified polystyrene resin composition having a melt flow rate of 1 to 20 g / 10 minutes by 5% by weight. |
