Antibacterial degradable environment-friendly plastic film

Abstract

The invention discloses an antibacterial degradable environment-friendly plastic film. The plastic film is prepared through the following raw materials in parts by weight: 50-60 parts of linear low-density polyethylene, 20-25 parts of polypropylene, 10-15 parts of disulfide carbamate, 10-15 parts of ethyecellulose, 10-15 parts of bamboo carbon powder, 3-7 parts of plasticizer, 5-9 parts of sodium alginate, 10-14 parts of zein, 5-10 parts of tartrate, 3-5 parts of 2-hydroxypropyl-beta-cyclodextrin, 3-5 parts of ASA high-glue powder, 2-4 parts of light degradation agent, 1-3 parts of light stabilizer, and 2-4 parts of cedarwood oil. The plastic film is tough, durable, recyclable, sanitary, harmless, environment-friendly, antibacterial, resistant to moisture and dust, easy to degrade, and outstanding in environmental protection effect; pollution to the land is reduced; the bamboo carbon powder is added in the formula and can release a large number of negative ions, and moreover, the smell absorbing performance, the antibacterial performance and the deodorizing performance are high.

Description

technical field

[0001] The invention relates to the field of packaging materials, in particular to an antibacterial, degradable and environment-friendly plastic film. Background technique

[0002] Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins that are used for packaging and as laminations. Plastic packaging and plastic packaging products are taking an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. At the same time, it is accompanied by the pollution of the environment by plastic films. Because the components of ordinary plastic films are difficult to decompose, they will stay in the soil for a long time, affecting plant growth, polluting the environment, and do not have antibacterial properties.
