4 Classification
4.1 Category of corrugated boxes
Corrugated boxes are classified into 2 categories and 20 types according to the maximum mass and inside dimension of length plus width and depth of the contents, circulation environmental conditions, and the different types of corrugated cardboard used, as shown in Table 1. The performance of the corrugated cardboard used for each type of corrugated box shall not be lower than the values specified in GB/T 6544-2008, Table 1. Category 1 boxes are mainly used in situations with relatively harsh circulation environments, while Category 2 boxes are mainly used in situations with better circulation environments.
