Abstract

The invention discloses an oil-proof packaging paper and belongs to the field of paper products. The oil-proof packaging paper is prepared by mixing paper pulp, surfactant and complex oil-proof components at a speed of 400-500 r / min for 40-60 minutes and then standing to obtain a mixed solution, mixing coalescing agent, plasticizer and compound additives into the mixed solution to obtain a pulp solution, melt-extruding the pulp solution at 150-200 and then cooling down to obtain a packaging paper base, and then feeding the packaging paper base into a packaging paper production line. The oil-proof packaging paper solves the problems that existing oil-proof packaging paper are non-significant in oil-proof effects and prone to producing toxic substance when applied to high-temperature food.

Description

technical field [0001] The invention belongs to the field of paper products, and in particular relates to an oil-proof wrapping paper. Background technique [0002] With the improvement of people's living standards and the strengthening of environmental protection awareness, many non-degradable plastic products are gradually being replaced by paper products, especially in the food packaging fields such as fast food and baking, and the demand for paper food packaging materials is increasing. Compared with plastic disposable tableware, the material of paper disposable tableware is more environmentally friendly and easy to degrade, and it is the main force of disposable tableware on the market. But because wood pulp fiber itself does not possess waterproof and oil-proof properties, it is very necessary to solve the problem of water-proof and oil-proof paper tableware. Therefore, oil-proof wrapping paper is gradually playing a role in people's daily life. [0003] At present, ...
