1. The design and processing of carton and carton are inseparable from the size. The inner diameter size is 3 mm higher than the maximum size of the contents.

2. If the corrugated base paper of the carton box is affected by air humidity, causing softness, blistering, unevenness, etc., this will greatly reduce the quality of the carton box. The carton box factory reminds everyone to do a good job of protecting the cardboard from getting wet.

3. According to customer requirements, the characters on the surface of the carton are sometimes uneven, and the size should be corrected in a timely manner to proofread the layout. If the printing quality of the layout is poor, it is because the viscosity of the ink is poorly controlled, and the cardboard is not flat under the state of conveying ink and paper.

4. In the process of making carton boxes, the carton flap is an important indicator, and general customers pay special attention to this. Attention should be paid to controlling the quality of materials, and good quality cardboard should be selected.
