Eco-Friendly Greaseproof Paper is a greaseproof paper without chemical additives. It is made of natural and renewable materials and has strong greaseproof and waterproof properties. It is widely used in the food industry and can directly contact food without contaminating it, meeting environmental protection and food safety standards.

                       

Production processRaw material selection: Natural fibers, such as renewable wood pulp, are used as the base material. In order to achieve the greaseproof properties, no chemical coating containing fluorine compounds is used.Pulp treatment: The wood pulp is mechanically or chemically treated to remove impurities and form a uniform pulp. According to the specific greaseproof requirements, the pulp can be further adjusted in process.Pressing: The treated pulp is pressed, and the fibers are arranged more closely through special mechanical equipment, so as to naturally form greaseproof properties. This step determines the thickness and density of the paper.Surface treatment: Some Eco-Friendly Greaseproof Paper will be surface treated, such as applying a natural coating (such as soybean oil or beeswax) to enhance its greaseproof and waterproof properties while maintaining its degradability.Drying and cutting: The formed oil-proof paper is dried to reach the specified moisture content. Finally, it is cut and packaged according to the required size and

Ruize specializes in selling Greaseproof Paper, which has good oil-proof properties and is often used in food packaging, cooking and storage, especially in applications that require protection from grease penetration.

The production of Greaseproof Paper usually involves the following steps:Pulp treatment: High-quality pulp is selected as the raw material and is chemically or mechanically treated to improve the strength and density of the paper.Pulp coating: To enhance the oil resistance, a thin layer of special coating (such as silicone oil or other oil-proof coating) is applied to the surface of the paper during the production process. This coating can effectively prevent grease from penetrating.Drying and calendering: Through the calendering and drying process, the surface of the paper is made smoother and denser, thereby enhancing its oil resistance and durability.Cutting and packaging: After production, Greaseproof Paper is usually cut into sheets of different sizes and packaged for shipment.

Greaseproof Paper's oil resistance comes from its high density of paper fibers and surface smoothness, which reduces the chance of grease penetration. During the production process, a thin layer of oil-proof coating (such as silicone oil) is applied to further enhance its oil-proof effect. Unlike wax paper, it maintains breathability, ensuring that food is dry without affecting freshness. These characteristics make it widely used in food packaging and baking fie

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.

Heat sealable waterproof paper can combine the basic structure of paper with waterproof and heat sealing functions. The paper base material is made of high-quality natural fibers, such as wood pulp or recycled pulp, to ensure that the paper has sufficient strength and toughness. At the same time, according to different application requirements, the thickness of the paper is also different, which can be used for food packaging or high-strength packaging in industry.

Heat sealable waterproof paper is coated with a waterproof coating such as polyethylene (PE) or polypropylene (PP) on the surface to have waterproof properties. It also adopts a double-sided coating design to ensure that the paper has comprehensive waterproof protection during transportation and storage. In addition, the paper also has a breathable design, which allows gas exchange while being waterproof, which is particularly suitable for some food packaging scenarios.

The design of the heat seal layer uses low melting point polymers such as EVA or LDPE. These materials can quickly form a strong seal through heat and pressure to ensure the safety of the package contents. The sealing temperature and time are precisely designed to ensure that it is suitable for common packaging equipment and provide a fast and reliable sealing effect.
