An egg carton, also named an egg box or egg crate, is a special container that is used to carry, store, or transport eggs. It was said that the egg carton was invented because of an argument between a local farmer and a hotel owner, the farmer’s eggs are often broken. So after many times of trials, people found egg cartons that could protect the eggs from collision during transporting. Therefore, egg cartons are becoming more and more popular on the market as the demand increases for eggs. In this condition, the egg carton machine is also coming into sight, in general, the egg cartons can be put with 12 eggs, but our egg carton machine can customize a variety of sizes for customers.

Working Process of Egg Carton Making Machine
Pulping making system
The primary raw material is waste paper, including boxes, newspapers, and corrugated cardboard. These materials are pulped in a hydrapulper, where impurities are separated. The pulp is then screened and processed through a deflaker to form a smooth slurry. This slurry is then prepared for the next stage of production using pulp molding equipment.
Forming system
The forming machine has various specifications such as 4 faces, 6 faces, 8 faces, and 12 faces, and is equipped with customized egg tray molds (egg cartons, fruit trays, cup holders, etc. molds can be replaced). It mainly operates using vacuum suction filtration technology. The prepared slurry in the slurry supply tank is transported to the molding machine. At this point, the molding machine starts to work. Through vacuum suction, the fibers in the pulp are evenly deposited on the surface of the forming die, and then extruded through the forming die and the transfer die to form a wet embryo of an egg tray. A large amount of moisture will be removed during vacuum suction, and the forming cycle generally ranges from 3 to 7 seconds. At this stage, the wet embryo has no hardness, but the basic prototype of the egg tray has been formed.
Drying system
After the egg cartons are formed, the wet egg tray embryos are transferred to a conveyor belt using a transfer mold. Sufficient hot air is then blown evenly across the surface of the pulp-molded products to remove the evaporated water. Once dried, the products proceed to the automatic stacking and shrink packaging process.
Hotpress system
Hotpress: The wet, molded cartons are automatically conveyed to the hotpress section.
Heating and Pressing: The hotpress machine applies heat and pressure simultaneously. Heated molds or plates ensure the cartons are dried quickly while maintaining their shape. The pressing action ensures the cartons have the right thickness and strength.
Continuous Operation: Unlike batch processing, an online hotpress system operates continuously, allowing the production line to keep moving without interruption.
