Abstract

The invention relates to a composite slip-increasing masterbatch for BOPP films, which is mainly used for BOPP films. A variety of slip agents are preferred in the present invention, and a composite formula is adopted to design a compound type slip enhancement masterbatch. It combines the advantages of various slip agents and is used in BOPP film, which has both optical properties and slip effects of the film, and avoids the disadvantages of using a single slip agent. The technology belongs to the field of functional polymer materials.

Description

technical field [0001] The invention relates to the field of functional macromolecular materials, in particular to a preparation process of a composite slip-improving masterbatch for BOPP films. Background technique [0002] Slip-enhancing masterbatch is generally added to the core layer of the film. After the film is made, the slip-enhancing masterbatch is fully mixed with the plastic, extruded and melted by an extruder, and the slip agent is uniformly distributed on the film core layer. Due to the incompatibility between the slip agent and the plastic molecules, the film migrates to the surface of the film after aging. After hours or days, the slip agent coats in a thin layer to form a lubricating layer. When the film is in contact with the film, it is equivalent to the contact of the lubricating layer to achieve a smooth effect. [0003] At present, single slip agents such as silicone, erucamide, oleic acid amide, stearic acid, etc. are mostly used in the slip enhancem...
