Problems solved by technology

However, the raw material for its production is petroleum, which is a non-renewable material, and this type of material is not degradable, such as PE coated paper, which is difficult to recycle, which will cause pollution and damage the ecological environment.
[0003] Paper has been used as a packaging material. Although it has the advantages of being renewable and degradable, as a packaging material, compared with polypropylene film (BOPP) or PE-type packaging materials, paper has no waterproof performance and cannot block air and moisture. Easily deformed and easily damaged
Used in food packaging, it will lead to a decrease in the shelf life of food, and it cannot be packaged for cold drink products

Embodiment 1

[0021] A production method of a rapidly degradable packaging material, the production method is to sequentially coat a moisture-proof material, a water-proof material and an oil-proof material on a base material, specifically comprising the following steps:

[0022] (1) On-line use an anilox roller with 240 lines to coat the moisture-proof material, and then dry it by infrared rays;

[0023] (2) Use a rubber roller to coat the water-based waterproof material and oil-proof material on the surface of the printing substrate coated with the moisture-proof material, and dry it with infrared rays to obtain the product. This product can be used to make boxes for packaging ice cream.

[0024] The base material is paper with a thickness of 0.43mm and a surface roughness less than 1.4um; the moisture barrier material is 20g of commercially available styrene-butyl acrylate-acrylic acid copolymer, commercially available acrylic acid self-adhesive emulsion 12g, 3g of commercially availabl...

Embodiment 2

[0026] A production method of a rapidly degradable packaging material, the production method is to sequentially coat a moisture-proof material, a water-proof material and an oil-proof material on a base material, specifically comprising the following steps:

[0027] (1) On-line use an anilox roller with 240 lines to coat the moisture-proof material, and then dry it by infrared rays;

[0028] (2) Use a rubber roller to coat the water-based waterproof material and oil-proof material on the surface of the printing substrate coated with the moisture-proof material, and dry it with infrared rays to obtain the product. The product can be used to make boxes for packaging pet food.

[0029] The base material is paper with a thickness of 0.05mm and a surface roughness less than 1.4um; the moisture barrier material is 15g of commercially available styrene-butyl acrylate-acrylic acid copolymer, 14g of commercially available acrylic self-adhesive emulsion , commercially available technic...

Embodiment 3

[0031] A production method of a rapidly degradable packaging material, the production method is to sequentially coat a moisture-proof material, a water-proof material and an oil-proof material on a base material, specifically comprising the following steps:

[0032] (1) On-line use an anilox roller with 240 lines to coat the moisture-proof material, and then dry it by infrared rays;

[0033] (2) Use a rubber roller to coat the water-based waterproof and oil-proof material on the surface of the printing substrate coated with the moisture-proof material, and dry it with infrared rays to obtain the product. This product can be used to make boxes for packing vegetables.

[0034] The base material is paper with a thickness of 0.6mm and a surface roughness less than 1.4um; the moisture barrier material is 25g of commercially available styrene-butyl acrylate-acrylic acid copolymer, commercially available acrylic self-adhesive emulsion 10g, 1g of commercially available industrial gra...

Abstract

The invention relates to a method for producing a quickly degradable packaging material, which is characterized in that: a dampproof material, a waterproof material and an oilproof material are coated on a substrate material in turn; and the method comprises the following steps of: (1) coating the dampproof material by using a 240-wire anilox roller, and drying by using infrared rays; and (2) coating the waterproof material and an oilproof material on the printing surface coated with the dampproof material by using a rubber roller, and drying by using infrared rays to obtain the product. Compared with the prior art, the quickly degradable packaging material has the advantages of oilproof, waterproof and dampproof performance, quick degradation and the like.

Description

technical field [0001] The invention relates to a packaging material, in particular to a production method of a rapidly degradable packaging material. technical background [0002] At present, in food packaging, polypropylene film (BOPP) or PE-coated packaging bags are generally used, which have many advantages such as moisture-proof, waterproof and oil-proof, and are not easily damaged. It is used in the market to pack ice cream, pet food, vegetables and other foods. However, the raw material for its production is petroleum, which is a non-renewable material, and this type of material is not degradable, such as PE coated paper, which is difficult to recycle, which will cause pollution and damage the ecological environment. [0003] Paper has been used as a packaging material. Although it has the advantages of being renewable and degradable, as a packaging material, compared with polypropylene film (BOPP) or PE-type packaging materials, paper has no waterproof performance a...
