Abstract

The invention discloses a moisture-proof packaging paper material, which is prepared from the following raw materials in parts by weight: paper mulberry bark fibers, pineapple leaf fibers, nano-filler, an antioxidant and waterborne polyurethane slurry. A preparation method of the moisture-proof packaging paper material comprises the following steps: beating the paper mulberry bark fibers, the pineapple leaf fibers and the nano-filler to prepare pulp; adding the antioxidant into the pulp, papermaking, and cooling to obtain frozen crude paper; coating the frozen made paper with the waterborne polyurethane slurry, and drying to obtain the moisture-proof packaging paper material. The packaging paper provided by the invention has the advantages of being waterproof, damp-proof and mildew-proof,and is excellent in mechanical properties, thus having a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a moisture-proof packaging paper material and a preparation method thereof. Background technique [0002] Wrapping paper is a general term for a type of paper used for packaging purposes, which can be divided into ordinary wrapping paper, special wrapping paper, trademark paper, oil-proof wrapping paper, and moisture-proof wrapping paper. For example, special fruit wrapping paper is thin and soft, photosensitive protective paper is opaque, oil-proof wrapping paper (vegetable parchment, etc.) has anti-grease penetration performance, and moisture-proof wrapping paper (bitumen paper, oil paper, aluminum foil, etc.) is moisture-proof , Trademark paper is used for packaging after printing. Wrapping paper usually has high strength and toughness, but its moisture protection performance is poor, which cannot meet people's needs. Contents of the invention [0003] Based on...
