Abstract

The invention discloses an anti-bonding master batch special for a BOPET aluminum laminated film, and belongs to the field of functional polymer materials. The anti-bonding master batch comprises thefollowing components (by weight): 80-100 parts of a PET base material, 0-15 parts of glass beads, 0-15 parts of polyorganosiloxane, and 0.1-1 part of an antioxidant, wherein the particle size of the glass beads is 5-7 microns; and the particle size of the polyorganosiloxane is 5-7 microns. The problem that there is no special anti-bonding master batch for the BOPET aluminized film capable of effectively reducing the friction coefficient of the BOPET aluminized film in the prior art is solved.

Description

technical field [0001] The invention relates to the field of functional polymer materials, and mainly relates to a special anti-bonding masterbatch for BOPET aluminized film. Background technique [0002] In recent years, the biaxially oriented polyester film (BOPET) industry has been developing at an astonishing speed, and its application range is also expanding, especially in the fields of printing and packaging. Due to its higher tensile strength, superior air barrier properties, better dimensional stability and chemical resistance, it has the potential to overwhelm BOPP films. Compared with other non-polar plastic films, BOPET film has a certain polarity, and its aluminized printing performance is better. However, in order to better improve its adhesion fastness during aluminum plating and printing, it still needs to be treated. [0003] Aluminized film refers to the film made by continuously evaporating single-sided metal on PET, CPP, BOPP and other plastic films by v...
