1 Raw materials: The main raw materials for producing molded pulp egg trays are newspapers, cultural paper, cardboard, paper boxes, and corner waste paper from paper mills, cardboard factories, or printing plants. The raw material resources are abundant, and the prices are low. Importantly, it achieves the comprehensive utilization of waste materials, contributing to certain social value.
2 Pulping: The primary raw material for making molded pulp egg trays, waste paper, is fed into a hydraulic pulper, where it is broken down into pulp fibers under the shear and friction forces of water flow. The pulp fibers enter the pulp storage tank. To enhance the appearance and cleanliness of the product, the pulp in the storage tank is screened to remove impurities (such as film pieces, hemp ropes, coarse debris) from the fiber pulp. Subsequently, the pulp is diluted to a certain concentration and finally pumped into the pulp box of the molding machine.
3 Molding: When the molding mold above the molding machine's pulp box is completely immersed in the pulp, the pulp is adsorbed and gathered on the mold surface under the suction of vacuum at the back of the molding mold. Due to the unique surface filtration and hollow structure of the molding mold, the pulp fibers in the gathered material adhere to the mold's surface, while water is drawn away. The fiber layer adhering to the mold's surface is approximately 2.5mm thick, forming the wet blank of the egg tray product, which contains about 70% water.
4 Drying: The wet blanks of the egg tray products need to be sent to the drying line (temperature 120-200°C) for dehydration and drying. After drying, the finished egg trays are ready for packaging and storage.
