Abstract

The invention provides a water soluble plastic packaging bag, and a preparation method thereof. The water soluble plastic packaging bag comprises, by weight, 10 to 40 parts of polyethylene, 10 to 30 parts of soybean starch, 5 to 20 parts of a plasticizer, 6 to 15 parts of zinc oxide, 1 to 5 parts of pine tar, 8 to 18 parts of allethrin, 5 to 10 parts of dibenzyl disulfide, 8 to 20 parts of salicylic acid, 3 to 8 parts of a surfactant, 5 to 12 parts of an antitack agent, 6 to 15 parts of polyoxyethylene ether, 2 to 10 parts of a pH conditioning agent, and 5 to 13 parts of an antiseptic. The water soluble plastic packaging bag is capable of dissolving in water completely; no harmful substance is generated; the water soluble plastic packaging bag is degradable, is friendly to the environment, is safe, and can be degraded in soil rapidly; the surrounding environment is not influenced; heat resistance is excellent; the water soluble plastic packaging bag is harmless for packaged products, is capable of prolonging product self life; heat stable time is 40min or longer at 180 DEG C; and damage is not easily caused.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a water-soluble plastic packaging bag and a preparation method thereof. Background technique [0002] As a packaging material, plastic packaging bags are widely used in the packaging of various products, such as pesticides, fertilizers, dyes, water treatment agents, concrete reinforcement materials and chemical reagents for gardening care; safe and convenient to use, avoiding direct contact by users The packaged objects can be used for the packaging of articles harmful to the human body. However, plastic packaging bags are not easy to degrade and seriously pollute the environment; although plastic packaging bags are processed in some places, the products of degradation treatment will also cause harm to the environment more or less, thus forming secondary pollution. Polyethylene plastic packaging products. It is a disposable packaging product with low price ...
