PROBLEM TO BE SOLVED: To provide a method for manufacturing a polyolefin film and a master batch comprising an anti-tack agent that provide a film manufactured from polyethylene or polypropylene that has a lowered tackiness without degrading the transparency, and that provides a solution to the problem of difficulty in opening the mouth of a pouch made of the film. SOLUTION: This film comprises a zeolite as an anti-tack agent. The diameter of the primary particles of this zeolite is not more than 0.4μm, and the diameter of the secondary particles formed from the primary particles is also not more than 0.4μm. The master batch for producing this film comprises (a) polyethylene (PE) or polypropylene (PP), and (b) the zeolite as the anti-tack agent. COPYRIGHT: (C)2005,JPO&NCIPI |
