Abstract

The invention discloses a plastic material used for fresh keeping boxes, which includes the following raw materials, by weight, 30-40 parts of a degradable plastic master batch, 15-30 parts of modified starch, 8-12 parts of a co-polymerized-type polypropylene, 2-4 parts of glycidyl methacrylate, 1-3 parts of glass fiber, 0.6-0.8 parts of ethylene glycol terephthalate, 2-4 parts of stearic acid, and 0.3-0.5 parts of an anti-oxygen agent. The plastic material is prepared from the degradable plastic master batch, so that the plastic material is degradable. The plastic material maintains the anti-impact, anti-oxidizing and corrosion-resistant properties of a package material in the prior art and can be degraded in environment after composting when being used, so that the plastic material greatly alleviates environment pollution. The plastic material is wide in use range and application prospect.

Description

technical field [0001] The invention relates to a plastic material for a fresh-keeping box. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Beverage bottles are mostly made of plastic products. The two materials, polyethylene and polypropylene, are non-toxic and tasteless, and are safe for the human body when used to fill beverages. However, once polyethylene is subjected to high temperature or acid corrosion, it will slowly dissolve and release organic solvents, which will cause harm to the human body. There are three types of plastic products widely used in food packaging: polyvinyl chloride, polyethylene, and polystyrene. It is not harmful to human health if it is used to hold cooking oil in a short period of time. But, use them to hold edible oil for a long time, can pollute food, cause the harm to human body. [0003] The element vinyl chloride in polyviny...
