3 Product classification
3.1 Thin sheet packaging paper is divided into three types according to its use: Type 1 (original thin sheet paper) is suitable for lining packaging of high-end commodities and can be used as carbon paper. Type II (original postal sealing paper) is suitable for lining packaging of general instruments and other commodities. Straight type (original thin glossy paper) is suitable for lining packaging of commodities and can be used as folk paper. QB/T3526—1999
Replaces ZBY32029—1990
3.2 Type I and Type II are divided into three grades: A, B and C according to their quality, and Type I is divided into two grades: B and C according to its quality. 3.3 Thin sheet packaging paper is flat paper with a size of 787mm×1092mm, or as specified in the order contract, the size error shall not exceed ±3mm, and the deflection shall not exceed 3mm.
