The production process is as follows:

Firstly, waste paper, the main raw material for making pulp-molded egg trays (boxes), is put into a hydraulic pulper and decomposed into pulp fibers under the shear force and friction force of water flow; Pulp fibers enter the pulp storage tank. In order to make the product look more beautiful and clean, it is necessary to screen the slurry in the slurry storage pool, that is, to remove impurities (film, hemp rope, coarse slag, etc.). ) in fiber pulp. At the same time, the slurry should be further ground. In order to make the egg tray (box) waterproof, it is necessary to add waterproof additives during grinding. After that, the slurry is diluted to a certain concentration and finally pumped into the slurry box of the forming machine. When the forming mold above the pulp box sinks and is completely immersed in the pulp, the pulp is absorbed and gathered on the surface of the mold under the suction effect of the vacuum on the back of the forming mold; Due to the unique surface filtration and hollow structure of the molding die, the pulp fibers in the aggregated slurry adhere to the die surface, while the water is pumped away. The fiber layer attached to the mold surface is about 2.5mm thick, which is the wet blank of egg tray (box) products. The water content is about 75%, and it needs to be sent to the drying line (temperature 80 ~ 120℃) for dehydration and drying. The finished product of dried egg tray (box) only needs to be packaged and put into storage.
