To achieve a water proof and oil-proof effect in disposable pulp tableware, the following steps can be taken:

Add food-grade additives: Food-grade additives can be added to the pulp during the pulp molding manufacturing process to improve the water resistant and oil resistant properties of the final product. Water proofing agent can be added at a rate of 1.0%-2.5%, while oil-repellent agent can be added at a rate of 0.5%-0.8%.

Use high-quality raw materials and good package: The use of high-quality raw materials is critical to producing disposable pulp tableware with good waterproof and oil-proof properties, such as sugarcane fiber, bamboo fiber, or other specialty fibers. Make molded pulp packaging in good condition , products should be sealed and packaged in a plastic bag immediately to ensure it is free from moisture.

Use specialized production equipment: The production of waterproof and oil-proof disposable pulp tableware requires specialized equipment, such as a pulp molding food packaging machine or a pulp tableware production line. These machines are designed to produce high-quality pulp products with consistent and reliable properties.

Test the product: To ensure that the disposable pulp tableware meets the required waterproof and oil-proof standards, it should be tested under various conditions, such as exposure to water or oil at high temperatures for a set period. The test time is generally 30 minutes, but special requirements may necessitate an extended test time.

In summary, achieving waterproof and oil-proof properties in disposable pulp tableware involves adding food-grade additives, using high-quality raw materials, using specialized production equipment, and testing the final product under various conditions. With the right approach, pulp molding food packaging machine manufacturers can produce high-quality and eco-friendly molded pulp food trays that meet the demands of the food industry.
