Abstract

The invention discloses a high-quality BOPP (Biaxially-oriented Polypropylene) film which is prepared from the following components in parts by weight: 100 parts of polypropylene master batch, 10-15 parts of natural zeolite powder, 1-3 parts of zinc oxide whisker, 1-2 parts of graphene, 1-2.5 parts of silicon dioxide, 0.5-1 part of hollow glass bead, 0.3-0.8 part of polypropylene wax, 0.5-0.8 part of antifoaming agent, 0.2-0.4 part of halogen-free flame retardant, 0.5-1 part of slipping agent, 0.5-1.5 parts of dispersing agent, 0.6-1.2 parts of antioxidant and 0.2-1 part of plasticizer. According to the formula of the high-quality BOPP film, a certain amount of natural zeolite powder is added; the zeolite powder has abundant gaps and strong adsorbability, so that the catalyst residues in polypropylene and the low-molecule polymers generated in polymerization process are stored in the gaps; the mazy gaps are criss-cross, so that the film is cooled before the extreme active low-molecule polymers rush out of the surface, some low-molecule polymers are prevented from rushing out of the surface and higher surface tension can be kept; the anti-static property and abrasive resistance are excellent.

Description

technical field [0001] The invention relates to the technical field of BOPP films, in particular to a high-quality BOPP film. Background technique [0002] BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. However, there are still some defects in the existing BOPP film: for example, some low-molecular polymers rush out of the surface layer during the reaction process, resulting in low surface tension; antistatic and wear resistance need to be further improved. Contents of the invention [0003] The object of the present invention is to provide a kind of high-quality BOPP film, to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A high-quality BOPP film made of the following components...
