What makes a good paper boxes supplier? Here, Dongguan Haiying color Printing Co., LTD., sharing experience. We have 18 years of experience in boxes customization. The Haiying brand is famous at home and abroad. Good quality has won the favor of customers. On how to customize a good carton. There are four areas you need to be aware of. The following is a brief introduction.
1. Materials of the Paper boxes supplier
According to the quality and size of the contents in the box, the Haiying paper box supplier chooses suitable surface paper and paper core. For different contents to choose different raw materials. Cardboard edge pressure strength is the surface of the ring pressure strength. In the box production process with high quality, high strength, the low gram weight of raw materials. This can improve the quality and reduce the cost. The experience of the Haiying paper box supplier is”Tissue paper is light. Core paperweight.
2. Design of the Paper boxes supplier
1. The length-width ratio of the carton (L/B)
The ratio of length to width on the bottom of the box is different. The compressive strength is also different. When the length-width ratio is 1.2 ~ 1.4. The maximum compressive strength of cartons is achieved. Haiying paper boxes supplier’s ratio of boxes is reasonable. It helps to improve the quality.
2. Carton height (H)
If the sides of the carton are the same length, the height should be between 20 and 25cm. So the higher the height, the lower the compressive strength; While the height was 25cm ~ 1m, the compressive strength hardly changed.
3. The perimeter length of the carton is Z=2(L+B).
When the carton height and other conditions are certain. When the perimeter of the carton is doubled, the compressive strength is increased by about 55%. Cartons with a circumference of 2m or less are easier to process. Its compressive strength is easy to meet the design requirements
4.”Angle cutting” processing
Cut the corners of the carton. After “Angle cutting” treatment, the compressive strength can be increased by 31%. Also can save the amount of paper, reduce damage.
3. Printing process
1. The square problem of the box
It mainly depends on the cardboard indentation line is up to the standard. The indentation line width of the carton is 12mm-17mm. Fold lines should be centered. When the cardboard is bilateral lines, the box is square; One sideline, the box is not square enough.
2. Whether the size is accurate
Although carton printing houses allow errors, within the permissible error range, the compressive strength is different. So the carton factory should try to reduce the error. Haiying paper boxes supplier uses high-quality raw materials, Fine workmanship, novel design, consumers trust.
3. Bonding pressure
Carton printing plant in the transmission printing, printing cylinder, and cardboard pressure after the completion of printing. If the pressure is a small picture and the text is not clear; Too much pressure on the surface of the text will appear concave-convex phenomenon. It affects the compressive strength of the carton after forming. The compressive strength of cartons with excessive printing pressure can be reduced by 30%~40%.
