▎ 摘  要

NOVELTY - Oil-proof paper, comprises base paper layer, adhesive layer and coating layer which are stacked successively. The adhesive layer includes enzyme-cleaved starch and the coating layer includes kaolin, latex, graphene, dispersant and carboxymethyl cellulose. USE - The oil-proof paper is useful as packaging container for accommodating oily food (claimed). ADVANTAGE - The oil-proof paper: has low cost and strong operability; utilizes silicon-free and fluorine-free materials, and thus avoids possible damage to human body; and achieves wide range of oil-proof grades; and is conducive to the realization of industrialization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of oil-proof paper, comprising taking base paper layer, coating adhesive layer coating material on base paper layer to obtain adhesive layer laminated base paper layer, and applying coating layer coating material on the adhesive layer laminated base paper layer to obtain final product.
