The panels used for collapsible boxes are PP honeycomb panels. Currently, honeycomb panels are available in two thicknesses: 4mm and 10mm. For manufacturing collapsible boxes, the 10mm thick honeycomb panel (weight: approximately 3000 grams per square meter) is primarily used. Honeycomb panels offer good structure, light weight, strong load-bearing capacity, and waterproof and moisture-proof properties. They are an excellent alternative to products such as cardboard boxes, wooden boxes, and metal boxes. Therefore, collapsible boxes are now widely used as environmentally friendly products.
