Abstract

The invention discloses a packaging wrapping film, which is characterized by being prepared from the following components as raw materials in parts by weight: 25 to 35 parts of a waste thermoplastic elastomer TPEE, 4 to 7 parts of waste aromatic oxadiazole fibers, 10 to 15 parts of vinyl-terminated nitrile rubber, 2 to 4 parts of rosin polyether sulfonate, 0.5 to 1.5 parts of pentaerythritol tetra-3-mercaptopropionate, 0.5-1.0 part of 1-allyl-3-methyl imidazole chloride, 0.2-0.4 part of an initiator, 0.1-0.2 part of phosphorus pentoxide and 0.2-0.5 part of an environment-friendly plasticizer. The invention further provides a preparation method of the packaging wrapping film. The packaging wrapping film provided by the invention is good in comprehensive performance and performance stability, high in tensile strength and tear strength, and good in penetration resistance and self-adhesion performance.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a packaging stretch film and a preparation method thereof. Background technique [0002] Packaging stretch film is a kind of packaging method that uses mechanical stretching device or manual stretching of the film to force the deformation stress at room temperature to wrap the goods tightly for transportation and storage. It is a very common packaging form in the world at present. . It can make the whole stack of goods stable and not loose, thereby reducing damage during transportation, and can also play a role in dust and moisture resistance. Packaging stretching film is widely used in chemical raw materials, chemical fertilizers, Single-piece or tray packaging and other bundled packaging for food, mechanical and electrical products, and textile products. [0003] At present, the packaging stretch film on the market mainly uses PE as the raw material. The production cost of...
