What is compostable greaseproof paper?Compostable greaseproof paper is a type of paper that has been treated to resist grease, making it ideal for packaging foods such as burgers, sandwiches, pastries and fried foods. Unlike traditional greaseproof paper, which often contains plastic or other non-biodegradable materials, compostable greaseproof paper is made from renewable resources and will naturally decompose in a composting environment without leaving harmful residues.
Main benefits of compostable greaseproof paperEnvironmentally friendly: The most important advantage of compostable greaseproof paper is its impact on the environment. It is made from biodegradable materials that break down quickly in composting conditions, reducing landfill waste and contributing to a circular economy. It offers a cleaner, more environmentally friendly alternative to traditional plastic-coated paper, which can take hundreds of years to decompose.
Grease resistance: Like traditional greaseproof paper, compostable greaseproof paper is designed to resist the oils and fats in food. This makes it a great choice for takeaway packaging, fast food packaging and baked goods, ensuring that food stays fresh and packaging remains functional.
Sustainability certification: Many compostable greaseproof papers come with certifications such as ASTM D6400 or EN 13432 that verify their compostability under industrial or home composting conditions. These certifications ensure that the paper meets s

With the improvement of environmental awareness and the concern about food safety, Greaseproof Paper Bags (Greaseproof Paper Bags), as an innovative, environmentally friendly and efficient packaging material, are gradually being favored by more and more industries. As a leading Greaseproof Paper Bag manufacturer, Ruize focuses on providing high-quality Greaseproof Paper Bags to ensure that every packaging product meets international standards and can meet customers' needs for personalized customization.
What is Greaseproof Paper Bag?Greaseproof Paper Bags are paper bags treated with special processes and have excellent oil and water resistance. Compared with ordinary paper bags, they can effectively prevent grease penetration and prevent food grease from contaminating the external packaging during storage and transportation. Therefore, this type of paper bag is particularly suitable for the catering and food industries, especially for scenes where greasy food needs to be wrapped.
Greaseproof Paper Bag Production ProcessThe production process of Greaseproof Paper Bag requires strict control of material selection and processing technology. First of all, manufacturers will use high-quality pulp as the main raw material. These pulps are specially treated to ensure that the paper itself has a certain oil resistance. Next, through mechanical processing, the paper is coated multiple times to form an oil-proof film layer, which further enhances the grease resistance of th

Biodegradable Greaseproof Paper is an environmentally friendly material, mainly made of natural plant fibers or bio-based polymers. This kind of paper can be degraded through natural processes after use, and will not exist in the environment for a long time like traditional plastic packaging, causing pollution.
Its degradation process usually includes the following steps:
1. Biodegradation:The degradation of Biodegradable Greaseproof Paper is first through the action of microorganisms. Microorganisms (such as bacteria and fungi) decompose the organic components in the paper and convert them into carbon dioxide, water and other harmless substances. This process can be completed within a few months in a suitable environment, depending on the temperature, humidity, thickness and composition of the paper.
2. Composting degradation:In a composting environment, Biodegradable Greaseproof Paper can also degrade rapidly. Composting is a process of converting organic waste into fertilizer through the action of microorganisms and other organic matter. Under composting conditions, this oil-proof paper will be effectively decomposed into harmless organic matter and finally become nutrient-rich soil fertilizer. This process usually occurs under warm and humid conditions.
3. Oxidative degradation:In addition, in the natural environment, Biodegradable Greaseproof Paper also undergoes oxidative degradation under the action of sunlight and air. The fibers and organic molecules

Specific applications of water-based coated paper in the food industry
Food packaging bags: Water-based coated paper is widely used to make various food packaging bags, such as bread bags, snack bags, candy bags, etc. The water-based coating can effectively improve the water resistance and oil resistance of the paper, prevent the moisture or grease of the food from penetrating to the outside of the packaging, and maintain the freshness of the food. This coating can also increase the strength of the paper bag, making the packaging bag less likely to break during transportation.
Application examples:Bread and pastry packaging: used to package fresh bread, cakes and biscuits, etc., water-based coated paper can prevent grease penetration and keep the packaging appearance neat.Ready-to-eat food packaging: such as potato chips, popcorn, etc., water-based coated paper improves the moisture resistance and sealing of the packaging, which helps to extend the shelf life of the food.Takeaway packaging boxes: With the rapid development of the takeaway industry, water-based coated paper is also used in food takeaway packaging boxes. Whether it is hot meals, cold meals or drinks, water-based coated paper can effectively resist the intrusion of external moisture and oil, keeping the takeaway food clean and tidy. It can also help maintain food temperature and prevent food from spoiling due to packaging problems.
Application examples:Fast food boxes and bento boxes: Water-based coa

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
