Grease-Proof Paper​

​Working Principle​: The reason why the oil-proof paper can resist oil is mainly through two methods. One is to use chemical wood pulp for high-intensity pulping treatment, making the paper fibers closely combined with very low porosity, thereby physically blocking the penetration of oil. The other method is to add or apply special oil-proof agents during the paper production process or on its surface.

Characteristics and Applications: This type of paper usually has a certain degree of strength, high smoothness, and low permeability. Some anti-oil papers also have high transparency. It is widely used in food packaging (such as for wrapping butter, sandwiches, and fried foods) and in cooking processes (such as when placed on a baking tray during baking)
