The invention relates to the technical field of biaxially oriented
polypropylene extinction films, and concretely relates to a matting material for BOPP, a preparation method thereof, and a BOPP matting film. The matting material for BOPP is prepared from, by weight, 40-60% of co-
polypropylene, 35-55% of high-density
polyethylene, 5-15% of a master batch A and 0.5-5% of an
antioxidant master batch, wherein the master batch A comprises a master batch matrix and hydrogenated
petroleum resin or
rosin resin, and the master batch matrix is
polypropylene. The preparation method of the matting material for the BOPP comprises the following steps: mixing the co-polypropylene, the high-density
polyethylene, the master batch A and the
antioxidant master batch in a high-speed mixer, and performing
extrusion granulation by adopting a double-screw extruder at an
extrusion temperature of 225-240 DEG C. The BOPP matting film prepared from the matting material for BOPP is good in overall
extinction uniformity, particularly, the glossiness of the two sides of the film is reduced, the
haze of the two sides of the film is improved, the thickness of a matting layer is reduced, and the production speedis increased.
