| titleOfInvention | Polypropylene film and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a suitable polypropylene film when used as a heat seal layer of a food packaging material. (A) a polypropylene block; (B) a copolymer elastomer block of propylene and an α-olefin having 2 to 12 carbon atoms (excluding 3), wherein the proportion of the copolymer elastomer block in the total copolymer is 5 to 30 mass %, And a propylene-α-olefin block copolymer having an intrinsic viscosity of 4.0 to 6.0 dl / g of a xylene-soluble component is obtained. A) a polypropylene film having the properties of (3) to (3). (1) M. The ratio of aspect ratios 1 to 3 in the D direction is 50% -100% (2) M.P. The ratio of the average particle size of 0.2 μm or less in the D direction is 4 The ratio of 5-80% and the average particle size of 0.4-1 μm is 20- 40% (3) M.P. The ratio of the circularity in the D direction of 1 to 1.2 is 60 to 9 5% and the ratio of roundness 1.2 to 1.4 is 30% or less |
