Abstract

The invention provides an environment-friendly plastic material. The environment-friendly plastic material is prepared from the following components in parts by weight: 42 to 50 parts of degradable plastic master batch, 15 to 23 parts of copolymerized polypropylene, 8 to 15 parts of glass fibers, 5 to 7 parts of stearic acid, 1 to 2.5 parts of ethylene terephthalate, 6 to 10 parts of carbon black,0.6 to 1 part of an antioxidant and 10 to 15 parts of modified starch. According to the environment-friendly plastic material provided by the invention, a plastic packaging material prepared from theraw materials including the degradable plastic master batch and the like has very strong degradability and keeps impact resistance, oxidization resistance and corrosion resistance of an existing packaging material; the environment-friendly plastic material can be absorbed by the environment and the pollution to the environment is greatly alleviated.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an environmentally friendly plastic material. 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 kinds of plastic products widely used in food packaging: polyvinyl chloride 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. ...
