Embodiment 1

[0029] Such as figure 1 Shown, a kind of manufacture method of frozen food wrapping paper is characterized in that, comprises the following steps:

[0030] 1) Select 100% imported kraft softwood pulp that does not contain fluorescent whitening agent substances, and obtain a pulp with a concentration of 3.5% and an average fiber number length of more than 1mm after pulping and beating;

[0031] 2) Add filter aid, water-resistant agent, reinforcing agent and bactericide to the slurry mixing tank, and mix slurry with the slurry in step 1);

[0032] 3) Purify and screen after pulping, and then go online to dehydrate the wire part;

[0033] 4) The pressing part adopts three presses with a positive pressure of 0.45MPa, a second pressure of 0.3MPa and a double pressure of 0.4MPa to form the wet paper. The water content of the press is controlled at 62%, and then enters the drying front to evaporate and dehydrate to a water content of 10%;

[0034] 5) Use compound surface glue liqui...

Abstract

In the present invention, by selecting kraft softwood pulp as raw material, pulping, beating, and adding various environmental protection additives, the refinement control of the process flow is improved, and a product with low temperature resistance, oil resistance, water resistance, anti-sticking, and anti-moisture cracking is prepared. The advanced frozen food packaging paper can replace traditional waxed paper, coated paper and plastic materials to ensure that the food in contact with it is safer and more environmentally friendly.

Description

technical field [0001] With the improvement of people's living standards; the requirements for food safety concepts have increased; the requirements of the world's ecological environment require products to have the concept of safety, environmental protection, and sustainable development; food packaging will bring about changes in laws and needs --- paper packaging will replace other materials Package. White and uncolored food packaging paper will become one of the main substitute products. White and uncolored food packaging paper is a product with the concept of environmental protection and sustainable development, and a product that guarantees food safety and quality. The technology relates to frozen food packaging, specifically an inner wrapping paper for frozen food. Background technique [0002] Due to the rapid development of the food consumer goods industry, it provides a good opportunity for the development of packaging materials. The development and production of f...
