Corrugated box selection principle
Jul 20, 2018

When selecting corrugated boxes, we must first consider the nature, weight, storage and transportation conditions and circulation environment of the products. Secondly, we should design according to the design principle of shockproof packaging and the design method of corrugated boxes. In addition, we must follow relevant standards, such as export packaging to meet international standards. Standard or foreign requirements, and must pass the relevant tests, so the corrugated carton packaging should generally pay attention to the following two points.

(1) Corrugated type of corrugated board The type of corrugated board is divided into four types according to the height of A, B, C and E. The mechanical properties of different corrugated board are also different. Type A corrugated board has the highest flat pressure and high compressive strength, while type B is the opposite. C-type flat pressure, vertical pressure, parallel pressure and cushioning force are better; thickness between corrugated board, type A is the largest, type C Secondly, the B type is again, the E type is the smallest, because the cardboard with small thickness is easy to bend, so the B-shaped corrugated paper is widely used for the packaging of the box with low pressure resistance. According to the corrugated board Mechanical properties, single-sided corrugated boxes with A or C type is good, double-sided corrugated boxes with A, B or B, C type combination is appropriate, close to the outer surface of the B type, can play an impact resistance. A, B type or B, C type combination can improve the physical and mechanical properties of the carton; compared with the printability, both B and C are good for printing.

(2) Box shape of corrugated box Under the premise of ensuring the quality of the carton, the processing materials and packaging cost of the carton should be saved as much as possible. For example, the carton with the same volume, the length: width: the most material when the height is 2:1:2, the most expensive when the ratio is 1:1:1. Therefore, we should try to avoid the use of square boxes. We must also take into account the utilization of the box volume of the product, the utilization of the tank to the volume of the truck and the train, and the stability of the stacking during storage and transportation.
