As corrugated carton machine manufacturer) and in order to reflect the combination of paper and corrugation (pit type) for each type of cardboard, corrugated cardboard is represented by a code, and there are three points to remember in the interpretation method:

3.1 Use English letters or numbers to represent paper quality, such as K3K, A=A, K3K3K, etc.

3.2 Use numbers to represent masses and pits, eg 3 for B pits and 9 for E pits. Then K3K (B pits), B9B (E pits).

3.3 Each letter or number generally represents a layer of paper (eg K3K3K cardboard, K is face paper, 3 is corrugated paper, K is medium paper, and the other K is bottom paper).
