Abstract

The invention relates to a composite matting masterbatch for BOPA film, the masterbatch is mainly used for BOPA film. In the present invention, a variety of matting agents are preferred, and a composite formula is adopted to design a composite matting masterbatch. It combines the advantages of various matting agents and is used in BOPA film, which has both the optical properties and matting effect of the film, and avoids the disadvantages of using a single matting agent. The technology belongs to the field of functional polymer materials.

Description

technical field [0001] The invention relates to the field of functional polymer materials, in particular to a preparation process of a composite matting masterbatch for BOPA films. Background technique [0002] BOPA is the English abbreviation of Biaxially oriented polyamide (nylon) film. Biaxially oriented polyamide (nylon) film (BOPA) is an important material for the production of various composite packaging materials. It has become the third largest after BOPP and BOPET films. Packaging material, biaxially oriented nylon film referred to as BOPA film, its main raw material is polycaprolactam, referred to as nylon 6 or PA6, this raw material is melt-extruded and cast on special equipment, and then longitudinally and transversely (or At the same time) stretching to make a film, that is, biaxially oriented nylon film. Outstanding tensile strength and puncture resistance, excellent high barrier properties to gases and odors, chemical resistance to grease and carbon oxides, w...
