Problems solved by technology

[0005] The matting performance of matting film comes from the matting material of the matting layer. At present, the production of matting film is to add a certain proportion of polypropylene to dilute the matting material to reduce the haze and improve the gloss. However, it is difficult to disperse the matting material and polypropylene evenly. , resulting in uneven matting effect on the entire film surface, and it can be clearly seen from the appearance that the surface of the film is cloudy

Abstract

The invention discloses a matte BOPP film and a preparation method thereof and belongs to the field of biaxially oriented polypropylene matte films. A semi-matting film is of a three-layer structure and consists of a core layer, an upper surface layer and a lower surface layer, wherein the core layer is an antistatic layer. The 1000 parts of matte BOPP film includes 659-984 parts of homo polypropylene, 36-165 parts of polyethylene-polypropylene blend, 0-165 parts of high-density polyethylene, 0-150 parts of ternary copolymerization polypropylene, 0-0.3 part of anti-adhesion agent, 2.1-8.4 parts of antistatic agent, 2.4-12 parts of modified nano-silica and 0.8-21 parts of modified nano titanium dioxide. The haze degree of the matte film is reduced, the matting effect of the matte film is softer, the matte BOPP film has stable and even matting effect, and the preparation method enables a production process to be easy to operate and control and convenient to popularize.

Description

technical field [0001] The invention relates to the field of a biaxially stretched polypropylene matt film, in particular to a BOPP film with a matt visual effect and a softer matting effect than ordinary matting films. Background technique [0002] According to the surface gloss of the product, the product is divided into three categories: glossy, matte and matte products: glossy products with a gloss greater than 70%, matte products with a gloss less than 15%, and the rest are classified as matte. products. The production technology of polypropylene matt film and glossy film is relatively mature, and there are many mass-produced glossy film and matte film products on the market, but there is no mature and available technology for matt BOPP film at present. The patent of the present invention discloses a matt BOPP film film. [0003] BOPP matting film is generally an ABC three-layer composite film. Layer A is the matting layer, which provides matting function. It is gener...
