Compared with other packaging materials, kraft paper packaging has two main advantages, one is environmental protection, and the other is cost saving. In the packaging market, environmental protection is the basic requirement of packaging. However, environmentally friendly packaging often means high standards and high costs – standards are all made out of money. The kraft paper packaging box takes care of these two advantages, and meets the requirements of general merchandise for packaging. The knapsack packaging box has excellent anti-drop performance, cushioning performance and stiffness. For small items, pure kraft paper packaging can be used. For large, delicate products, kraft paper boxes with foam, sponge, EVA and other materials can be easily handled.
