Description

Oil-proof glue for papermaking
Technical Field
The invention relates to the technical field of preparation of oil-proof glue for packaging paper, in particular to an oil-proof glue for packaging paper, which can replace a PE film.
Background
The laminated packaging paper is mainly used for industrial packaging of bearing flanges and the like, food packaging of popcorn, fried chicken, hamburgers and the like, and mainly comprises two layers, namely a first layer of paper base material and a second layer of PE film material. The PE plastic film is blown on the paper surface, the PE plastic film is 10-20 g per square paper surface, the PE film has the function of blocking engine oil or vegetable oil, but in the process of recovering defective products after the use of the PE packaging paper is finished, the PE plastic film is contained on the surface, so that paper-making enterprises are difficult to recycle, the PE plastic film is not degraded during storage in the environment, and the PE plastic film belongs to plastic garbage and can only be used for incineration treatment. Therefore, the development of a degradable paper material for replacing a PE plastic film is easy to recycle, meets the national environmental protection policy, and particularly has a certain trend of developing a new technology for replacing a PE film by a plastic-free material under the global plastic-limiting trend.
At present, most of the domestic oil-proof adhesives are imported products, wherein the oil-proof agents containing fluorine chemical additives are forbidden to be used for food packaging and food contact paper products, and most of the domestic popularized oil-proof adhesives are imported products such as America and Japan, and have high price and complex process, so that the development of the domestic environment-friendly fluorine-free waterproof oil-proof adhesive instead of a PE film coating is a necessary technology for responding to national plastic restriction and plastic prohibition.
