Antibacterial and antiseptic waterproof packaging paper

Abstract

The invention discloses antibacterial and antiseptic waterproof packaging paper which comprises a paper body, antiseptic layers, bamboo rind layers, LLDPE films and surface layers. The antiseptic layers coat the upper surface and the lower surface of the paper body, the bamboo rind layers coat the surfaces of the antiseptic layers, the LLDPE films coat the surfaces of the bamboo rind layers, and the surface layers coat the LLEDPE films. Each antiseptic film is formed by polypropylene, polystyrene, sodium malate and methylcellulose in a mixing mode, and each surface layer comprises a cellulose thin film layer and an antibacterial layer coating the cellulose thin film layer. On the basis of the prior art, antiseptic effects of the packaging paper is greatly improved, the bamboo rind layers which are stuck to the packaging paper enable the packaging paper to have better hardness and toughness, and the packaging paper can be directly used for being manufactured to be a packaging box or a gift bag. The LLDPE thin films are contacted with food, the paper is not directly contacted with the food, therefore, lots of bacteria on the surface of the paper and chemical components of the paper are isolated, and the antibacterial and antiseptic waterproof packaging paper better conforms to sanitary and environmental requirements, is excellent in waterproof and oil-proof effects, can completely avoid permeation of water and oil, and facilitates usage for packaging. The antibacterial layers coat the cellulose thin film layers, and the antibacterial effect of the paper is good.

Description

technical field [0001] The invention relates to an antibacterial, antiseptic and waterproof packaging paper, which belongs to the technical field of packaging. Background technique [0002] In the past, considerable effort has been devoted to the development of preservative-containing papers. Since cellulose, the main component of paper, is an excellent growth medium for molds, especially under hot and humid conditions, the use of preservatives is essential. These compounds act as "fungicides," which prevent the growth of mold. [0003] Existing antifungal agents for food wrapping paper are deficient in aspects such as working effect and production cost. Moreover, the hardness and toughness are relatively poor, and it does not have waterproof and oil-proof properties. [0004] Moreover, the existing milk powder packaging films generally do not have antibacterial function. Even if some milk powder packaging films have antibacterial function, their antibacterial ...

Problems solved by technology

[0003] Existing antifungal agents for food packaging paper are deficient in terms of work effect and production cost.

Moreover, the hardness and toughness are relatively poor, and it does not have waterproof and oil-proof properties.

[0004] Moreover, the existing milk powder packaging film generally does not have antibacterial function, even if some milk powder packaging film has antibacterial function, its antibacterial effect is not ideal, and its waste will cause huge damage to the natural ecology
