Method for producing noodle packing paper

Abstract

The invention relates to a method for producing noodle packing paper, which is mainly characterized by comprising the following steps of: blending poplar chemical mechanical pulp, bleached sulfate softwood pulp and bleached sulfate hardwood pulp serving as fiber raw materials, treating by using a thick pulp sieve, seasoning, slushing, desanding and degassing, sizing, performing fine screening, dewatering and forming a mesh part, squeezing, before-drying, performing surface sizing, after-drying, calendering, reeling, and packing, wherein the weight percent ratio of the poplar chemical mechanical pulp to the bleached sulfate softwood pulp to the bleached sulfate hardwood pulp is (16-25):(25-35):(45-55); during surface sizing, a lubricant and enzyme converted starch are mainly involved and compounded in a weight ratio of (1-5):20; and the glue concentration of the surface of the starch is 6 to 8 percent, and sizing amount is 1 to 4g / cm<2>. The food grade lubricant is used for surface sizing to improve the friction coefficient of a paper surface, the high-yield chemical mechanical pulp is used for making the noodle packing paper by optimizing the process, and the smoothness of the paper surface still can be ensured under the condition that pulping energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to a production method of wrapping paper, in particular to a production method of noodle wrapping paper. Background technique [0002] For a long time, a large number of plastic products have been used in food packaging. Because plastics are extremely difficult to degrade and plastic waste is difficult to dispose of, a large amount of plastic packaging is used for food, which is easy to cause waste of resources and environmental pollution. Plastic food bags have become one of the main sources of "white pollution". . Therefore, developed countries have introduced regulations to limit the use of plastic packaging. In order to build an "environmentally friendly and resource-saving" society, my country has banned the production, sale, and use of ultra-thin plastic shopping bags since June 1, 2008, and implemented regulations such as the paid use of plastic shopping bags to limit the use of plastic shopping bags. Food packaging paper...

Problems solved by technology

It is produced by fully chemical wood pulp, and the pulp yield and resource utilization rate are low; the product has low whiteness and low grade, which limits the scope of use of the product

[0005] Domestic noodle packaging mainly exists: the use of raw and auxiliary materials and processes is difficult to meet clean production requirements, and it is difficult for products to meet the "Hygienic Standards for the Use of Additives for Food Containers and Packaging Materials" (GB9685); in addition, noodle packaging is prone to scratches Many domestic manufacturers have made a lot of explorations on the problems of noodles, noodle breakage and paper damage, but it is still difficult to achieve a satisfactory packaging effect for users
