China's packaging industry is currently in a healthy development period, so the demand for paper and cardboard is very large. As an important packaging material, cardboard has always played a very importantrole. The development of paper-forest integration project is very important for China.

There are three types of cardboard commonly used in China, white cardboard, container board and corrugated base paper. In the category of white cardboard, coated white cardboard is the highest-grade product, followedby coated white cardboard, and the lowest grade is uncoated gray-bottomed white cardboard. More than ten years ago, China still used this low-grade product. Mainly white cardboard.

Most of the white paperboard produced in China is coatedwhite paperboard. It is worth noting

that in China, coated white paperboard isalso used as the face paper of some medium and

high-grade corrugated boxes instead of cardboard. For boxboard, ordinary boxboard and kraft boxboard eachaccount for

nearly 50%. The 50% of kraft liner boards are almost all producedwith imported waste paper,

and those produced with virgin kraft pulp only account for a very small proportion and are difficult to count, and some are only used in their flour pulp. Then nearly 50% of ordinary container boards areproduced with very

backward technical equipment and poor quality raw materials.The market is under great

pressure on these products and are gradually beingeliminated. In corrugated base paper, the

proportion of high-end products isthe lowest among the three major categories, and the

high-strength corrugated base paper is less than 1/3. Here we can see why China imports a large amount of high-strength corrugated base paper every year. The root cause of its low output is not that there is no market for it, but that we do not have the raw materials needed to produce it, or cannot obtain such raw materials at acompetitive price.
