Extinction material for biaxially oriented polypropylene (BOPP) film and preparation method for extinction material

Abstract

The invention relates to an extinction material for a biaxially oriented polypropylene (BOPP) film and a preparation method for the extinction material. The extinction material is characterized by comprising the following raw materials in part by weight: 30 to 60 parts of polypropylene (PP) resin, 30 to 60 parts of high density polyethylene, 2 to 15 parts of inorganic extinction powder, 2 to 10 parts of polybutylene terephathalate (PBT), 1 to 3 parts of dispersing agent and 0.1 to 1.0 part of antioxidant, wherein the total parts of the components are 100. By the extinction material for the BOPP film, a uniform extinction layer can be provided, high haze and high-temperature resistance are achieved, an extinction layer can be thinned for a BOPP film manufacturer, and the production speed and production efficiency of the extinction film are improved.

Description

technical field

[0001] The invention relates to a matting material for BOPP (biaxially oriented polypropylene) film and a preparation method thereof, which is used for the matting layer of the BOPP matting film, improves the thermal stability of the film, increases the haze, and can reduce the thickness of the surface layer of the matting film. Background technique

[0002] The matting film can be used in food packaging (biscuits, dried fruits, tea, cakes, etc.) after being compounded to create an image of a natural product, while the covers of books, periodicals and magazines and posters can be laminated with matting film to obtain a non-reflective Appearance, giving a soft feeling and good hand feeling. If the matting film is combined with the packaging paper (or carton), the grade of the packaging can be significantly improved. This kind of packaging is widely used in tobacco, wine, clothing, footwear, perfume, cosmetics, medicine and other high-end daily necessities. A...
