Abstract

The invention relates to packaging paper, and provides food packaging paper having good anti-oil performance and good fresh-keeping effect, and allowing packaged food to be non-toxic and safe. The food packaging paper comprises a base paper layer, an anti-oil layer, a fresh-keeping agent layer and a starch film layer which are successively arranged in an overlapped mode; the anti-oil layer is composed of chitosan, acetic acid, sodium alginate and deionized water; the fresh-keeping agent layer comprises a film-forming water-soluble carrier and a fresh-keeping agent, wherein the fresh-keeping agent is arranged in the film-forming water-soluble carrier and is formed by mixing propolis and sucrose fatty acid ester with ethyl alcohol. The preparation method of the food packaging paper comprises the steps of preparing a coating composed of chitosan, acetic acid, sodium alginate and deionized water, preparing the fresh-keeping agent formed by mixing propolis and sucrose fatty acid ester with ethyl alcohol, and successively arranging the anti-oil layer, the fresh-keeping agent layer and the starch film layer on the base paper layer.

Description

technical field [0001] The invention relates to the technical field of wrapping paper, in particular to a food wrapping paper and a preparation method thereof. Background technique [0002] Traditional wrapping paper is a general term for three types of paper mainly used for packaging purposes. It usually has high strength and toughness, can withstand pressure and folding, and has simpler quality requirements than cultural printing paper and other paper types. There are many subdivided paper types, each with different properties and uses. The paper used for food inner packaging needs to be in direct contact with food, and has the characteristics of cleanliness, non-toxicity, and no germs. However, as people's requirements for food packaging The improvement of traditional food inner packaging paper can no longer meet the requirements of shelf life in terms of oil resistance and so on. Contents of the invention [0003] Therefore, in view of the above problems, the present ...
