Issues on carton packaging box molding process

1. The effects of box template design

There's a huge effect of the carton packaging structural design on whether the box can be produced with automatic packaging machine. In many cases it is due to the size of some part of the carton packaging box unreasonable result in the product can not be produced on automatic packaging machine, or the loss rate is too high. Now there are lots of carton box packaging design software available for the box template structural design, for example, Packmage CAD software which gives fully consideration on the cardboard caliper and lock style in the carton packaging structural design.

2. The effects of step and repeat

The paper can be divided into two kinds according to the fiber orientation. As for the orientation of the paper fibers, the visual can tell the difference under normal circumstances. During the printing process, the external force on the paper caused the deformation of paper, when the external forces cancellation, the paper back to its original state the ability to call tensile strength, it is related to the paper fiber arrangement. So in the step and repeat process, under the rule step and repeat the carton packaging as much as possible, it should keep the carton box opening direction parallel to the cardboard fiber orientation direction to ensure the opening of the carton box not too large, and due to the tension of the paper fibers, leaving the tray after forming uneven, irregular in the molding process, thus ensuring the packaging machine is easy to open box, smooth production.

3. The effects of temperature and humidity

Under different temperature and humidity, the shape of the carton packaging will change. New paper produced in short time, the water content is too high, it is easy to deform and bend. Therefore, the new paper should be stored a month or more, so that the paper moisture content could adopt to the ambient humidity.

4. The effects of die-cutting and creasing

In the die cutting creasing process, the quality of the arrangement of knife is the key to ensure the quality of processing, but also the precondition to ensure that the carton packaging molding process. The direction of the creasing line on the cardboard has certain effect on the width of the creasing line, in order to have ideal width of creasing line, the direction of the creasing line on the printing surface can not be ignored.

There is often a folded cardboard box deformed before the packaging line process which affects the smooth production, the protection of the carton packaging is very important. Usually use cardboard boxes to store the carton packaging has been folded. In general, try not to stack the box from the bottom which might break the pre-folding carton.
