ANTI-STICKING MASTER BATCH FOR BOPE FILM, PREPARATION METHOD THEREFOR, AND USE THEREOF

WIPO Patent Application WO/2024/037440

A1

Disclosed in the present invention is an anti-sticking master batch for a BOPE film. The raw materials for preparing same comprises, in parts by weight, 80-100 parts of matrix resin, 5-15 parts of an anti-sticking agent, 0.5-1.5 parts of an antioxidant and 0.1-1.5 parts of a dispersing agent. The present invention uses LDPE and MLLDPE having melt indices of 1.5-6 g/10 min synergistically, so as to improve the compatibility and dispersity of the anti-sticking agent and the matrix resin, thus reducing the impact of the master batch on later film processing, and ensuing the good surface quality of films. In addition, as the combination of synthetic silicon dioxide, PMMA microspheres and glass microbeads serves as the anti-sticking agent, the prepared film has excellent anti-sticking performance, the surface of the film has a relatively low friction coefficient, and the film surface has the optical performance of high transparency.
