A paper egg tray manufacturing machine is a type of equipment that is used to produce paper egg trays in large quantities. The machine can make egg trays of different sizes and shapes by molding and drying a mixture of recycled paper and water. Egg trays are typically designed to hold a dozen eggs, though some are also made to hold 18 or 24 eggs. They are usually moulded into a series of small, individual pockets, each of which is designed to hold one egg. The pockets help keep the eggs in place and prevent them from rolling around and potentially cracking during transport.
