[0002] Heavy bag packaging usually refers to packaging used to transport granular or powdered materials. The load-bearing range of each bag is usually 10-50KG, and the most common is 25KG heavy bag. In the packaging operation of materials, some packaging materials may have strong water absorption or are prone to deterioration after contact with air. After the materials are packaged, the packaging bags need to be vacuumed to achieve the purpose of isolating the air and protecting the materials. However, this type of material is relatively loose, and there is more air between the materials in the natural stacking state, and the overall volume is large. In order to facilitate the packing of materials or to place them neatly and not take up space, the packaging bags need to be vacuumed and shaped into a hexahedron for easy storage.
