Importance of surface treatment in paper food trays

Waterproof and oil-proof performance
In the food packaging industry, paper food trays often face challenges from liquids such as oil stains and soup. If the tray is not effectively surface treated, liquids can easily penetrate the paper, causing the tray to deform, break, and possibly contaminate the food. Ningbo Shuohui New Material Technology Co., Ltd.'s paper food trays use advanced waterproof and oil-proof technology, and form a dense waterproof and oil-proof barrier by spraying food-grade matte paint or other special coatings. This barrier can effectively prevent liquid penetration, ensure that the tray remains flat and strong, and thus ensure the hygiene and safety of food.
Improved aesthetics
Surface treatment not only improves the practicality of paper food trays, but also significantly enhances their aesthetics. Ningbo Shuohui New Material Technology Co., Ltd. provides a variety of surface treatment options, including matte, glossy and special textures, to meet the personalized needs of different customers. These treatments not only make the trays look more upscale and textured, but also can be customized according to different dining scenes and festive atmospheres, further enhancing consumers' dining experience.
Enhanced durability
Paper food trays with professional surface treatment are particularly good in durability. The waterproof and oil-proof coating effectively protects the trays from food residues and liquids, thereby extending their service life. At the same time, these coatings enhance the trays' resistance to tearing and abrasion, making them more durable during transportation and storage. This durability not only reduces the company's operating costs, but also improves the market competitiveness of the products.
Compliance with environmental standards
The surface treatment materials of paper food trays of Ningbo Shuohui New Material Technology Co., Ltd. all meet international environmental standards, ensuring that the products can be naturally degraded after use, thereby reducing the impact on the environment. This feature is particularly important for merchants and consumers who pursue green catering. With the improvement of environmental awareness, the use of degradable packaging materials has become an inevitable trend in the development of the industry.

Production process and manufacturing links of paper food trays

Raw material selection and pulp preparation
The production process of Paper Food Trays begins with the careful selection of raw materials. Ningbo Shuohui New Material Technology Co., Ltd. is committed to selecting high-quality raw materials from waste paper such as waste newspapers, cartons and paper tubes. These raw materials are strictly sorted, pulped and mixed, and finally processed into pulp that meets production requirements. In order to ensure the purity and stability of the pulp, Ningbo Shuohui New Material Technology Co., Ltd. uses advanced pulping equipment and technology to ensure that each batch of pulp meets high quality standards. This link lays a solid foundation for subsequent production and ensures the consistency and reliability of the product.
Mold design and molding
During the mold design stage, the engineers of Ningbo Shuohui New Material Technology Co., Ltd. carefully designed and manufactured special molding molds according to the specific needs of customers. The design of the mold not only determines the shape and size of the product, but also directly affects the structural strength and aesthetics of the product. In the molding process, Ningbo Shuohui uses vacuum molding technology to evenly pour the prepared pulp into the mold, and through vacuum adsorption, the pulp is tightly attached to the surface of the mold to form a semi-finished wet blank pulp. This advanced technology not only improves the accuracy and consistency of the product, but also significantly improves production efficiency, providing customers with high-quality customized products.
Hot pressing and drying treatment
The wet blank pulp semi-finished product is hot pressed to further enhance its structural strength. Ningbo Shuohui New uses efficient hot pressing equipment to precisely control temperature and pressure, so that the pulp can be quickly solidified under high temperature and high pressure conditions to form a tray with excellent strength and hardness. The shaped trays then enter the drying system, where they are dried using hot air circulation and heat sources such as steam to remove excess moisture and ensure that the product reaches the ideal degree of dryness. This process not only improves the stability and durability of the trays, but also lays the foundation for subsequent processing.
Shaping, trimming and surface treatment
The dried trays need to be shaped to eliminate the mesh marks that may be generated during the production process and to improve the density and smoothness of the product. On this basis, Ningbo Shuohui uses a professional trimming machine to accurately cut the trays to ensure that the edges of each tray are neat and the size is accurate. In the surface treatment stage, Ningbo Shuohui provides a variety of options, including matte, glossy and special textures, to meet the personalized needs of customers. These surface treatments not only enhance the visual beauty of the product, but also enhance its waterproof and oil-proof properties, thereby significantly extending the product's service life.
Quality inspection and packaging and warehousing
Each batch of Paper Food Trays must undergo strict quality inspection before leaving the factory. Ningbo Shuohui New Material Technology Co., Ltd. is equipped with advanced testing equipment and professional technicians to conduct comprehensive tests on the size, strength and waterproof performance of the products to ensure that the product quality meets national standards and customer requirements. Qualified products will be sent to the packaging line for counting, separation and stacking, and then packaged using automated packaging equipment. Finally, these finished pallets will be properly stored in the warehouse for shipment, providing high-quality packaging solutions for the catering industry.
