Polypropylene resin composition and biaxially stretched film |
| abstract |
(57) [Problem] To provide a polypropylene resin composition which is excellent in film stretchability in the longitudinal and transverse directions and can produce a biaxially stretched film with less thickness and unevenness. The propylene homopolymer and the propylene / α-olefin random copolymer comprise: 100 parts by weight of a polymer composition having an α-olefin content of 0.3 to 1.6% by weight and an isotactic pentad index of 0.94 or more was mixed with polyalkylene glycol and / or solid at room temperature. Alternatively, the composition contains 10 ppm to 1 part by weight of a higher fatty acid ester of a trihydric or higher polyhydric alcohol, and is suitable for forming a biaxially stretched film. Here, it is preferable that the propylene homopolymer is composed of 20 to 60% by weight and the propylene / α-olefin random copolymer is composed of 40 to 80% by weight. |
