PROBLEM TO BE SOLVED: To obtain a drawing polypropylene film, excellent in transparency and external appearance and capable of suitably using as a film for package because it is difficult to be injured when the films are together rubbed. SOLUTION: A drawing film containing 0.01-1wt.% of globular grains with a globularity degree of more than 0.8, which a 50% diameter in the volume integration distribution obtaining by a laser diffranction-scattering method is 0.5-5μm and the S value shown in the equation is 0.1 1, is obtained. However, D10, D50 and D90 respectively indicate 10%, 50% and 90% diameters in the volume integration distribution. |
