The customer asked me what the material of the carton was, and my carton factory said it was A * C. What does that mean? Please explain it to experts, thank you! ! bow ...

AXC's cartons do not refer to cartons made of Grade A paper and Grade C paper. Here, A and C are just a piece of code. The quality of paper in different regions is different, and the weight is even different. What is certain now is that grade A paper is rarely produced in China, and it is even more difficult to buy. A-grade paper is pure wood pulp, which is basically the same as imported American cards, so domestic agents generally have the same A-grade paper.
