[0002] In order to facilitate the transportation of stacking trays, packaging boxes, etc., these materials will be stacked and then wrapped with plastic film. The packaging film can not only play a protective role, but also limit the position to prevent the trays from loosening during transportation. When the stacking tray is in use, the packaging film will be removed first, and then the stacked trays will be removed.
