The raw materials of Custom Greaseproof Paper mainly come from high-quality wood pulp. Wood pulp is a kind of pulp made from wood by chemical or mechanical methods, which has the characteristics of long fiber, high strength and easy bleaching. When making oil-proof paper, high-quality wood pulp is usually selected as the raw material to ensure the strength and toughness of the paper. At the same time, the wood pulp needs to be specially chemically treated to give it oil-proof properties.
Specifically, some special chemicals are added in the manufacturing process of oil-proof paper, such as oil-proof agents and waterproofing agents. These substances can be closely combined with wood pulp fibers to form a dense oil-proof layer on the surface of the paper. This oil-proof layer can effectively prevent the penetration of liquids such as grease and water, thereby protecting the fiber structure inside the paper from damage.

Greaseproof Paper, also known as greaseproof paper, is a special paper commonly used in food packaging and baking. Its characteristic is that it can effectively resist grease penetration, ensuring that the appearance and texture of food will not be affected by grease. So how is this greaseproof paper made? Let's understand its production process and working principle together.
1. Selection of raw materialsThe production of Greaseproof Paper begins with the selection of raw materials, mainly using wood pulp. Wood pulp usually comes from sustainable forest resources. Wood is treated by mechanical and chemical methods and broken down into fibers, laying the foundation for subsequent paper production.
2. Pulping processAfter the initial treatment of wood pulp, it enters the pulping process. At this stage, the wood fibers will be further refined. The purpose of pulping is to crush the fibers and make them very small, which is a very important step. By processing the fibers more densely, paper with a tight structure and low porosity can be produced, which is also the basis of Greaseproof Paper's oil-proof function.
3. Papermaking and calendering treatmentAfter the pulping is completed, the pulp will be evenly spread in the paper net, dehydrated and formed into paper. At this point, the paper already has a certain thickness and strength. To make the paper more dense, the paper will go through a process called **supercalendering**. Supercalendering is to pass
