[0002] When producing environmentally friendly food preservation packaging bags, the bags need to be sterilized and dried. This requires the use of an ultraviolet sterilization and drying structure, which includes a drying box combined with a conveyor belt. It typically consists of a drying box, ultraviolet sterilization lamps, and a conveyor belt.
