Acceptable quality level (AQL)
6.1 Marking and packaging shall be carried out in accordance with the provisions of QB/T45 "Paper Packaging and Marking". Each roll of paper should be accompanied by a product certificate. If it is a downgraded product, the reason for the downgrade should be noted on the quality inspection certificate. 6.2 The joints of the rolls should be firm and flat, and the upper and lower layers should not be allowed to stick together. The width of the joints should not exceed 30mm. 6.3 The number of joints per roll should not exceed 3, and the joints should be marked with colored paper or color on the end of the roll. 6.4 The roll is rewound with a layer of plastic film on the rewinder, and then rolled with no less than three layers of computer continuous recording format base paper or kraft paper with a quantitative of 80g/m2. Finally, it is wrapped with three layers of 80g/m2 wrapping paper. Each end of the roll is padded with a round wrapping paper. 6.5 The roll core should be firm and not flattened. If there is a flattened and deformed roll core, the difference in its inner diameter should not exceed 5mm. 6.6 The width of the plastic woven belt for bundling the roll should not be less than 10mm. Each end of the roll should be tied with a circle, and the joints should be connected by heat. 6.7 When transporting the product, a canopy and clean transportation tool should be used. 6.8 When transporting and stacking, the rolls should be rolled on a flat ground or plank in the direction indicated on the rolls, but there should be no hard objects such as sand, gravel, coal slag, etc. on the ground or planks to avoid damaging the rolls. 6.9 The products should be properly stored to prevent the influence of rain, snow and damp ground. 6.10 The bottom rolls of horizontal stacking should be padded with curved boards, and the stacking height should not exceed three layers. 6.11 It is not allowed to drop the rolls from a height.

Appendix A
Method for determining the horizontal quantitative difference
(Supplement)
Take single-layer paper samples of 10cm×10cm uniformly along the width direction of the roll, take eight points for a roll width of 1050mm, and take four points for a roll width of 830mm, number the paper samples, and weigh them with a balance with a sensitivity of 0.01g. A3 Calculation
Calculate the difference between the maximum and minimum values, and the result is expressed in grams/meter?. Additional remarks:
