Embodiment 1

[0020] A water-soluble plastic packaging bag, comprising the following components in parts by weight: 30 parts of polyvinyl alcohol with an alcoholysis degree of 66%, 20 parts of starch, 10 parts of dibutyl phthalate, 6 parts of zinc oxide, pine 1 part of tar, 10 parts of allethrin, 4 parts of benzyl disulfide, 2 parts of salicylic acid, 1 part of sodium fatty acid, 5 parts of glass microspheres, 6 parts of fatty alcohol, 2 parts of sodium carbonate, and 5 parts of nitrite.

[0021] The preparation method of the above packaging bag includes the following steps: first mix the raw materials evenly to make a water-soluble glue, then cast and coat it on a mirror stainless steel belt, enter the drying room to dry until the moisture content is 5%, and remove it from the steel belt after film formation. Peel off, trim and roll.

Embodiment 2

[0023] A water-soluble plastic packaging bag, comprising the following components in parts by weight: 40 parts of polyvinyl alcohol with an alcoholysis degree of 78%, 30 parts of starch, 20 parts of dibutyl phthalate, 7 parts of zinc oxide, pine 2 parts of tar, 12 parts of allethrin, 10 parts of benzyl disulfide, 20 parts of salicylic acid, 10 parts of sodium fatty acid, 20 parts of diatomaceous earth, 13 parts of polyoxyethylene ether, 10 parts of potassium carbonate, and 15 parts of sulfur dioxide.

[0024] The preparation method of the above-mentioned packaging bag includes the following steps: first mix the raw materials evenly to make a water-soluble glue, then cast and coat it on a mirror-finished stainless steel belt, enter a drying room to dry until the moisture content is 8%, and remove it from the steel belt after film formation. Peel off, trim and roll.

Embodiment 3

Abstract

The invention discloses a water-soluble plastic packing bag and a preparation method thereof. The water-soluble plastic packing bag comprises the following compositions: by weight, 30-40 parts of polyvinyl alcohol, 20-30 parts of starch, 10-20 parts of a plasticizer, 6-7 parts of zinc oxide, 1-2 parts of pine tar, 10-12 parts of allethrin, 4-10 parts of bis benzyl sulfide, 2-20 parts of salicylic acid, 1-10 parts of a surfactant , 5-20 parts of an antisticking agent, 6-13 parts of a penetrating agent, 2-10 parts of a pH regulator, and 5-15 parts of a preservative. The water-soluble plastic packing bag is degradable and environmentally safe, can be rapidly degraded in soil, does not affect the surrounding environment, has good heat resistance and no harm to packaged products, and can extend the life cycle of the products.

Description

technical field [0001] The invention relates to the field of plastics, in particular 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 and is widely used in daily li...
