Abstract

The invention discloses a plastic packaging film, and relates to the technical field of plastic packaging product processing and production. The plastic packaging film is characterized in that the plastic packaging film is prepared from the following materials in parts by weight: 16 to 21 parts of polyvinyl chloride, 3 to 6 parts of modified kaoline powder, 7 to 11 parts of resin, 2 to 4 parts of methyltrimethoxysilane, 2 to 5 parts of a coupling agent, 3 to 5 parts of alkyl sodium sulfonate, 1 to 4 parts of waterborne polyurethane, 4 to 8 parts of talcum powder, 2 to 5 parts of tri-n-butyl citrate, 3 to 6 parts of an anti-aging agent, 5 to 8 parts of an accessory ingredient and 14 to 18 parts of clean water. The method is reasonable, and the plastic packaging film is non-poisonous, harmless and high in tenacity.

Description

Technical field: [0001] The invention relates to the technical field of processing and production of plastic packaging products, in particular to a plastic packaging film and a preparation method thereof. Background technique: [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition or polycondensation of monomers, commonly known as plastics or resins. It can freely change its composition and shape. It is composed of synthetic resins and fillers, Plasticizer, stabilizer, lubricant, colorant and other additives. [0003] The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important...
