The invention discloses a BOPP film with endurable and smoothness characteristics. The BOPP film is formed by a core layer, a surface layer and an inner layer through co-extrusion and combination. The surface layer comprises, by weight, 96.0%-96.8% of homo-polypropylene resins, 0.1%-2.0% of slipping agents and 0.1%-2.0% of antiblocking agents. The core layer comprises, by weight, 99.5%-99.7% of homo-polypropylene resins and 0.3%-0.5% of antistatic agents. The inner layer comprises, by weight, 84.1%-84.9% of homo-polypropylene resins, 14.0%-14.9% of slipping master batches and 0.1%-2.0% of antiblocking agents. The invention also discloses a preparation method for the BOPP film. The slipping master batches are prepared from homo-polypropylene resins, nano inorganic materials and slipping agents through the synergistic effect and are added in the inner layer components, the finally prepared BOPP film has various performances same as a common BOPP film, and can delay loss of the slipping agents in the product. Thus the slipping system plays a lasting and effective role, the packaging film has durable slipping characteristics in a certain time quantum, and the packaging speed is ensured.
