Box type design requirements and production design requirements of common folding cartons

Box type design requirements for common folding cartons

1. One-piece carton design

Cosmetic bottle carton design requirements: the cosmetic bottle is easy to break, and a buffer and fixed structure should be designed during the design. The cosmetic bottle can be placed in the center of the packaging box. To vacate the bottom, there must be a certain distance between the bottle body and the side of the carton.

2. Linear carton design

In order to ensure the normal operation of the automatic packaging machine, generally speaking, the linear carton design will increase the closing size of the lock. This is because after the size increases, the box cover and the box bottom tongue can be more easily inserted into the box body on the automatic packaging machine.

If it is hand-wrapped, the closing of the lock will generally be relatively small, which can ensure a beautiful appearance.

3. Reinforced self-locking bottom carton design

Since the structure of the conventional cardboard carton packaging cannot meet the needs of supporting heavy objects, the lower part of the carton will be made into a reinforced self-locking bottom structure. The advantage of this design is that the heavy objects in the box can be prevented from falling off, and the aesthetics of the printing is also improved.

Production design requirements for common folding cartons

1. Reasonable design of life size

Carton boxes are generally glued using a box-gluer machine. When designing the carton structure, attention should be paid to designing a reasonable life size:

The width of the gluing tray of the roller gluing method is 5mm, and the width of the living space can be planned to be about 15mm.

Assuming that the width of the living mouth is reduced, a gluing tray with a width of 3mm is selected when gluing boxes.

It should be noted that the width of the living area can be planned to be about 20mm, and the minimum width cannot be less than 15mm.

2. Reasonable design of folding line

In order to avoid paper jams, this kind of carton can be designed to be as arc as possible, and it can also be designed to be non-rounded, and part of the window can be connected to the carton according to the curve and node to make the glue box, and it can also be assembled Part of the window is opened when the carton is opened.

When designing the carton, it is necessary to avoid line recognition errors. In this type of situation, because the line to be folded is designed to look like "mark line + knife line", the curve is partially broken, and the repulsive force generated is much smaller than that of other curves. When sticking small boxes Can be folded properly.

If the folding line of the carton adopts a toothed knife line, then an indentation strip can be installed under the toothed knife line that needs to be folded during die cutting to reduce the rebound force of the toothed knife line and ensure the accuracy of the line recognition.
