With the continuous reduction of wood resources and the deterioration of the natural environment, the research and development of new packaging materials to replace the use of wood has attracted more and more attention from the industry. Many new packaging materials such as high-strength corrugated composite boards, heavy corrugated boards, and honeycomb paperboards have gradually become new packaging materials that replace wood packaging materials. Play the role of replacing wood and metal with paper, reducing resource consumption and packaging costs in a low-carbon economy.

The heavy-duty corrugated box made of heavy-duty corrugated cardboard is a rigid paper container, which has the advantages of light weight, good structural performance, shockproof, cushioning, foldable, strong printability, environmental protection and recyclability, and can be used to a large extent. It replaces wooden heavy-duty crates and becomes the workhorse of shipping packaging. At the same time, heavy-duty corrugated packaging boxes are green and environmentally friendly products, which are conducive to environmental protection, loading and unloading and transportation. In the fierce competition of many packaging materials, heavy-duty corrugated boxes have become the most important packaging materials in modern packaging by virtue of the above-mentioned unique advantages.
