Abstract

The invention discloses an antistatic and antifouling plastic film for packaging, which is made of the following raw materials in parts by weight: 50-80 parts of low-density polyethylene, 30-45 parts of linear low-density polyethylene, and 2-2 parts of plasticizer 5 parts, 0.5-1.2 parts of antistatic antifouling additive, 0.5-1 part of heat stabilizer, 1-2 parts of lubricant; with low density polyethylene and linear low density polyethylene as the main raw materials, in order to solve the existing packaging plastics The film is not resistant to static electricity. Antistatic and anti-fouling additives are added to the plastic film formula. The excellent antistatic properties of the produced plastic film avoid the adsorption of dust. The plastic film mixed with silicone endows the packaging bag with anti-fouling ability. Make it better play the role of packaging, practical and convenient.

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,...
