Abstract

The invention discloses aluminum-foil paper for preventing cigarettes from being damp and a production method of the aluminum-foil paper. The aluminum-foil paper comprises an aluminum foil layer, the two surfaces of the aluminum foil layer are compounded with a paper layer and a polyester film layer respectively, the surface of the paper layer is coated with a lining layer, and the polyester film layer is compounded on the aluminum foil layer through a water-soluble glue layer. The polyester film layer and the lining layer are compounded on the two surfaces of the aluminum-foil paper respectively, therefore, the use thickness of aluminum foil is reduced, the malleability of the aluminum foil layer is improved, and unnecessary wrinkles are prevented from happening to the aluminum-foil paper. The dampproof performance, freshness retaining performance and sealing performance of the aluminum-foil paper are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil paper, in particular to an aluminum foil paper for moisture-proofing cigarettes and a production method thereof. Background technique [0002] Nowadays, aluminum foil paper is a very common packaging material, which can improve the grade of packaged goods, and is widely used in the trademark and packaging of high-end goods. The aluminum foil manufacturing process in the prior art is: aluminum ingot smelting→casting and rolling→cold rolling→aluminum foil wool→multi-rolling→slitting→packaging, that is, the calendering method. The aluminum foil made by this method has good ductility, and the thickness is about 6.5 μm, and then it is combined with paper to make aluminum foil composite paper, which plays the role of moisture-proof, fresh-keeping, and sealing. That is, the composite aluminum foil paper of the prior art comprises four layers from bottom to top: paper, glue, aluminum foil and varni...
