Abstract

The invention discloses an anti-static anti-fouling plastic film for packaging. The anti-static anti-fouling plastic film is prepared from the following raw materials in parts by weight: 50-80 parts of low-density polyethylene, 30-45 parts of linear low-density polyethylene, 2-5 parts of a plasticizer, 0.5-1.2 parts of an anti-static anti-fouling additive, 0.5-1 part of a heat stabilizer and 1-2 parts of a lubricant. According to the invention, the low-density polyethylene and the linear low-density polyethylene are used as main raw materials; in order to solve the problem that an existing packaging plastic film is not resistant to static electricity, the anti-static anti-fouling additive is added into a formula for the plastic film, so dust adsorption is avoided due to the excellent anti-static property of the manufactured plastic film; and a packaging bag is endowed with anti-pollution capacity since the plastic film is doped with organic silicon, the packaging effect of the packaging bag is better played, and the packaging bag is practical and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to an antistatic and antifouling plastic film used for packaging. Background technique [0002] At present, there are three main types of common plastic film packaging bags on the market: polyethylene (PE), polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC) packaging bags. And fresh-keeping bag or fresh-keeping film are often used in people's daily life, are used for protecting the freshness of food, have made things convenient for people's life. The packaging of the current fresh-keeping bags or plastic wraps is basically shrink-wrapped, which will fall apart after opening, and the film or bag itself has static electricity and will absorb dust or oily fumes, which is unhygienic for packaging food or articles. Contents of the invention [0003] The object of the present invention is to provide a kind of antistatic and antifouling plastic film for packaging,...
