What are the classifications of functional masterbatch for biaxially oriented film?
Functional masterbatch for biaxially oriented film: UV barrier masterbatch, high transparency masterbatch, opening masterbatch, anti-aging masterbatch, anti-hydrolysis masterbatch, light diffusion masterbatch, matte masterbatch, pearlescent masterbatch, flame retardant masterbatch Granules, etc.;
Today we will focus on understanding the open masterbatch for biaxially oriented film. What is the open masterbatch? What role does it play?
The opening masterbatch for biaxially oriented film uses SiO2 as the opening agent, with a content of 6%. After special dispersion treatment, it has strong anti-adhesion and dispersion properties. It can be evenly dispersed in the film and form many layers on the surface of the film. The fine and hard protrusions reduce the contact area between the films and achieve the purpose of reducing the friction coefficient of the film surface, making it easier for the film to open. At the same time, due to the existence of these protrusions, external air can easily enter between the two films. , to avoid the formation of a vacuum between the two layers of film that are laminated together, thereby preventing the film from adhering. This masterbatch has the advantages of good high temperature resistance and compatibility, and does not precipitate or decompose during processing and use, and has good color.
The ratio of open masterbatch for biaxially oriented film:
It is recommended that the content of silica on the surface of the film should be within the range of 700-1200ppm, and the appropriate amount should be determined through testing to achieve both opening and haze control within a reasonable range without affecting the winding.
