Abstract

The invention relates to the technical field of papermaking industry, and in particular, relates to film transfer coating food paper for a fourdrinier vat paper machine and a preparation method of the film transfer coating food paper. The film transfer coating food paper for the fourdrinier vat paper machine comprises a body paper layer, a 1# coating layer coated on the reverse side of the body paper, and a 2# coating layer coated on the front side of the body paper; a 1# coating of the 1# coating layer is composed of the following raw materials in parts by weight: 4 to 5 parts of amphoteric surface cassava starch, 10 to 12 parts of a DSM coating, 2 to 4 parts of polyvinyl alcohol and 84 to 90 parts of water; a 2# coating of the 2# coating layer is composed of the following raw materials in parts by weight: 10-15 parts of polyvinyl alcohol and 90-100 parts of water. The film transfer coating food paper for the fourdrinier vat paper machine has the characteristics of water resistance, oil resistance, high temperature resistance and reusability, can completely replace paper-plastic composite coated paper to be used for packaging various foods, and has a wide prospect. The invention also provides a preparation method thereof.

Description

Technical field [0001] The present invention relates to the field of papermaking industry, and more particularly to a long mesh cylinder paper film transfer coated food paper and a preparation method thereof. Background technique [0002] With the enhancement of people's environmental awareness, with the vast development space of paper-shaped food packaging products. At present, there are many food packages for food packaging for food packaging, which is a showerhead paper and PE membrane composite products, which is still not easy to degrade. Disadvantages, long-term, potential will be eliminated, and after the food original paper is applied, the food paper made of food paper has waterproof, oil, resistant to high temperature, and repeatedly recycled, it is possible to completely replace paper-plastic composite lumines. Paper is used in a variety of food packaging, the prospects are broad. [0003] Patent CN201810419935.1 discloses a degradable food paper and a preparation metho...
