Packing paper with two waterproof surfaces

Abstract

The invention relates to a packing paper with two waterproof surfaces. The packing paper with two waterproof surfaces is characterized in that an inner layer and an outer layer of the packing paper with two waterproof surfaces are respectively coated with linear low density polyethylene (LLDPE) membranes through a film coating machine. The packing paper with two waterproof surfaces has the advantages that food pollution risks are greatly reduced; a food does not directly contact with a paper material but with the LLDPE membranes on the inner layer and the outer layer of the packing paper provided by the invention, so that the food is separated from a mass of bacteria on the surface of the paper material and chemical components of the paper material, and health and environmental protection requirements are satisfied; and the LLDPE membranes which are food-grade membranes can thoroughly prevent water and oil penetration, and thus effects of water resistance and oil resistance are excellent and packaging and use are convenient.

Description

technical field [0001] The invention relates to a food wrapping paper, in particular to a double-sided waterproof wrapping paper. Background technique [0002] At present, there are many wrapping papers on the market, which do not have waterproof and oil-proof functions. For example, the packaging of many cakes is directly a piece of ordinary paper. Not only is it not waterproof and oil-proof, but the quality of the paper cannot be guaranteed. People are using these packages directly. When using paper, it is easy to contaminate food. On the one hand, it is because the chemical composition of the paper itself contaminates food. On the other hand, because the paper is very easy to absorb moisture and produce moisture, it is easy to breed bacteria. Contents of the invention [0003] The object of the present invention is to provide a safe, convenient and waterproof wrapping paper with good waterproof and oilproof performance. [0004] The present invention is achieved like t...
