Problems solved by technology

This aluminum foil paper uses vanillin, isothiazolone, and compound oil as antibacterial agents. Vanillin and compound oil can be released outside the aluminum foil paper to prevent mildew on cigarettes, but there are the following problems: non-volatile antibacterial agents It can only prevent mold from growing inside the aluminum foil paper. After opening, the anti-mold effect on cigarettes is poor, and the volatilization loss of volatile antibacterial agents is not controlled. After a period of storage, aluminum foil paper will lose its anti-mold effect on cigarettes.

Abstract

The invention relates to the technical field of papermaking, and discloses aluminum foil lining paper with damp-proof and antibacterial functions and a preparation method of the aluminum foil lining paper. The aluminum foil lining paper is prepared from the following raw materials in parts by weight: 40-50 parts of softwood pulp, 50-60 parts of hardwood pulp, 15-25 parts of talcum powder, 20-25 parts of aluminum sulfate, 18-23 parts of alkenyl succinic anhydride and 5-8 parts of calcium oxide-sodium alginate / bletilla striata polysaccharide-liquorice essential oil microcapsules. In the preparation process, the calcium oxide- sodium alginate / bletilla striata polysaccharide-liquorice essential oil microcapsules are added into a sizing liquid. The calcium oxide-sodium alginate / bletilla striatapolysaccharide-liquorice essential oil microcapsules are used as a damp-proof and antibacterial agent, so that the mildew-proof requirements of the aluminum foil lining paper and cigarettes in low-humidity and high-humidity environments can be met, excessive loss of liquorice essential oil in the low-humidity environment can be prevented, and the antibacterial and mildew-proof effects of the aluminum foil lining paper are more lasting.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an aluminum foil backing paper with moisture-proof and antibacterial functions and a preparation method thereof. Background technique [0002] Aluminum foil backing paper is the base paper material of composite aluminum foil paper, and composite aluminum foil paper can be obtained by bonding it with aluminum foil through glue or paraffin. Composite aluminum foil paper has good moisture-proof, mildew-proof and fragrance-preserving properties. It is a composite packaging paper that has developed rapidly in recent years. It is the most widely used in the cigarette industry and is mostly used in the inner packaging of high-end cigarettes. Although aluminum foil itself has good moisture-proof and mildew-proof ability, when the package is opened, it can no longer maintain the airtight environment inside the package, and water vapor can easily enter through the opening, causing the ...
