| titleOfInvention | Polypropylene biaxially stretched film |
| abstract | [PROBLEMS] To combine the flexibility and low elongation characteristics of polypropylene, which has both flexibility and stickiness resistance, while maintaining the characteristics of a propylene-based stretched film that is excellent in the appearance of the film such as transparency and gloss. A biaxially stretched film is provided. SOLUTION: Using a metallocene catalyst, 30 to 80 wt% of a propylene-ethylene random copolymer (A1) having an ethylene content of 0.1 to 7 wt% in the first step and from the copolymer (A1) in the second step. Is a propylene-ethylene random block copolymer obtained by sequential polymerization of 20 to 70 wt% of a propylene-ethylene random copolymer (A2) containing 6 to 15 wt% of ethylene, and a melt flow rate ( 2.16 kg, 230 ° C.) is in the range of 0.1-10 g / 10 min, and in the temperature-loss elastic modulus (tan δ) curve obtained by solid viscoelasticity measurement, propylene-ethylene having a single peak below 0 ° C. A block copolymer (A) is formed by stretching in the film flow direction and in a direction perpendicular to the film flow direction. Propylene biaxially stretched film. [Selection figure] None |
