Problems solved by technology

[0003] However, for food materials, the traditional way is to use plastic boxes for packaging, but the cost of plastic box packaging is relatively high
If carton packaging is used, the cartons in the prior art will be easily deformed or damaged because the cartons in the prior art will be permeable, that is, the water-resistant paper in the prior art will still be permeable, and its water absorption is usually more than 45%
In addition, the preparation process of the water-resistant paper in the prior art is complicated and the production cost is high

Abstract

The invention relates to the technical field of paper making, in particular to a production method of paper with high water resistance. The production method comprises the following steps: step 1, boiling out a high-concentration water-resistant glue solution; step 2, preparing a low-concentration water-resistant glue solution; step 3, storing the low-concentration water-resistant glue solution; step 4, performing sizing on paper; step 5, performing surface sizing on paper. The paper with high water resistance, which is produced by using the production method provided by the invention, is low in water absorption degree (20%-35%), therefore, the paper with high water resistance, which is produced by using the production method provided by the invention, is suitable for packaging food supplies of cold-chain transportation. The production method of the paper with high water resistance has the characteristics of being simple in preparation method, low in production cost, and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production method of high water resistance paper. Background technique [0002] With the development of the logistics industry, a large amount of materials need to be packaged, stored and transported. However, for some food materials, they can only be transported in the cold chain, which requires the packaging boxes of food materials transported in the cold chain to have strong water resistance properties. [0003] However, for food materials, the traditional way is to use plastic boxes for packaging, but the cost of plastic box packaging is relatively high. If carton packaging is used, the cartons in the prior art are easily deformed or damaged because the cartons in the prior art are permeable, that is, the water-resistant paper in the prior art is still permeable, and its water absorption is usually more than 45%. In addition, the preparation process of the water-resis...
