Food plastic packaging bag and preparation method thereof

Abstract

The invention discloses a food plastic packaging bag and a preparation method thereof, and belongs to the field of packaging, wherein the food plastic packaging comprises the following raw materials by weight: 25-30 parts of polyethylene, 44-48 parts of polylactic acid, 15-20 parts of polycarbonate resin, 10-20 parts of polyethylene terephthalate, 23-25 parts of castor bean fiber, 6-8 parts of jute fiber, 12-14 parts of sisal fiber, 5-7 parts of natural zeolite powder, 7 to 9 parts of diatomite, 3 to 5 parts of calcium carbonate, 2 to 4 parts of an antibacterial agent, and 2 to 4 parts of a degradation promoter. The food plastic packaging bag has excellent degradation performance, and has the advantages of high mechanical strength, tensile strength, light weight and good tear resistance.

Description

technical field

[0001] The invention relates to the field of packaging, in particular to a food plastic packaging bag and a preparation method thereof. Background technique

[0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. With the rapid development of my country's economy, the level of purchasing power and consumption willingness of domestic residents are gradually increasing, and consumption concepts will tend to further improve the quality of life. In particular, food packaging materials are in direct contact with the packaged food, which has been widely valued because it will affect the safety of food and thus affect the safety of human body.

[0003] The current food packaging bags have begun to be made of degradable materials, but the general degradable materials have the disadvantages of high britt...
