Problems solved by technology

However, the existing high-grade food packaging base paper mainly relies on imports, and some domestic food packaging base papers are mainly produced from wood pulp, resulting in high production costs. Moreover, the paper products have poor water resistance and cannot be used to hold cold drinks and Beer has no obvious advantage in the market competition with plastic cups

Embodiment 1

[0027] In a factory in Guangxi, the pulp ratio is 65% bleached bagasse pulp and 35% bleached coniferous wood pulp. The bleached coniferous wood pulp and bagasse pulp are respectively decomposed, beaten, blended, screened, purified, and passed through 2670 fourdrinier multi-cylinder Paper system, its copying width is 2670mm, the design speed is 300m / min, and the papermaking working speed is 200-250m / min for paper cup base paper.

Embodiment 2

[0029] Except that the pulp ratio is 70% bleached bagasse pulp and 30% bleached softwood pulp, the rest of the processes are the same as in Example 1.

Embodiment 3

[0031] Except that the pulp ratio is 68% bleached bagasse pulp and 32% bleached softwood pulp, the rest of the processes are the same as in Example 1.

[0032] The base paper for food packaging produced by the invention meets the quality composite index requirements, can reduce the consumption of chemical wood pulp by more than 70%, fully utilizes abundant bagasse raw materials, reduces the production cost of the base paper, and improves the quality of the base paper. Table 1 is the various physical indicators of the paper cup base paper produced in Example 1.

Abstract

This invention relates to one method to process foods package paper by cane trash pastry with high formula, which comprises the following components: bleach needle wood pastry for 30 to 35 percentages, bleach cane trash pastry for 65 to 70 percentages, wherein, the pastry adopts three layers of core, bottom and surface with concentration controlled between 0.5 to 0.6 percentages, wherein, controlling each pastry formula through each pastry net concentration and flow speed; when original paper shapes it adds layer spray starch and then adds SM-I special glue agent to improve original paper anti-transparency to product high quality package materials.

Description

technical field [0001] The invention relates to a method for producing base paper for food packaging with high proportion bagasse pulp. Background technique [0002] As a high-grade packaging material, base paper for food packaging is mainly used to produce disposable degradable paper cups, paper tableware and other food packaging materials. Food packaging materials such as paper cups and paper tableware produced by using this base paper are very versatile, whether it is hot drinks or frozen drinks, they can be used to hold and drink. Using disposable paper tableware is far more hygienic than using multiple-use metal, glass or ceramic tableware, and it is easy to dispose of. On the other hand, paper is more suitable for printing than other packaging materials, and can easily print various exquisite patterns or characters on its surface, which is helpful for promotion. These advantages make paper tableware quickly become the most popular table...
