Embodiment Construction

[0010]

[0011] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0012] A kind of food packaging paper production method of the present embodiment, comprises the following steps:

[0013] Put 8% chitosan, 8% acetic acid, and 6% sodium alginate into deionized water and stir to obtain a rough mixture;

[0014] The crude mixture is vacuum degassed to obtain a finished product;

[0015] Choose 80g / m 2 base paper, coated with the finished product, the coating weight is 6 g / m 2 , and dry in an oven at 80°C for 3 minutes.

[0016] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.

Abstract

Embodiments of the invention disclose a food package paper preparation method, which comprises the following steps: adding 0.5-8% of chitosan, 0.5-10% of acetic acid, and 0.1-12% of sodium alginate into deionized water, and uniformly stirring to obtain a crude mixture; carrying out vacuum degassing on the crude mixture to obtain the finished product; and selecting 70 or 80 g / m<2> base paper, adopting the finished product to coat, and drying for 3-4 min in a drying oven with a temperature of 60-80 DEG C, wherein a coating amount is 4-8 g / m<2>. With the present invention, the package paper can be completely degraded after using, no toxic substance is precipitated when the package paper contacts a food, and food security can be ensured.

Description

technical field [0001] The invention relates to a method for making food wrapping paper, in particular to a method for making coated food wrapping paper. Background technique [0002] At present, most food packaging uses plastics as raw materials. These materials release a certain amount of toxic substances during food preservation, which are difficult to decompose in landfills after use, and incineration produces a large amount of toxic gases, which endanger human health. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a method for making food wrapping paper. The packaging paper can be completely degraded after use, and no toxic substances are precipitated during the contact with food, ensuring food safety. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a method for making food wrapping paper, comprising the following steps: [0005] ...
