Casting polypropylene film with controllable friction coefficient and preparation method thereof

The invention discloses a casting polypropylene film with a controllable friction coefficient and a preparation method thereof, belonging to the technical field of packaging materials. The casting polypropylene film sequentially comprises a corona layer, a middle layer and a heat-seal layer with a thickness ratio of (20-30) to (50-65) to (15-20). The corona layer is made from homo-polypropylene or polypropylene random copolymer, the middle layer is made from isotactic homo-polypropylene, and the heat-seal layer comprises 90wt%-98wt% of propylene copolymer, 1wt%-3wt% of adhesion resisting agent and 1wt%-7wt% of macromolecule slip agent, namely silicone master batch. The preparation method sequentially comprises the following steps: mixing materials, extruding to form a film, cooling for shaping, measuring thickness, aureoling, trimming, reeling, performing aging treatment, and slitting. The heat-seal layer is uniformly dispersed in main body resin by the macromolecule slip agent, and the slip agent is well compatible with the main body resin due to high molecular weight, and thus a film surface friction coefficient is prevented from being changed by migration of the macromolecule slip agent due to temperature of a storage or usage environment.
