When selecting corrugated boxes, first consider the nature, weight, storage and transportation conditions and circulation environment of the product, then design according to the design principle of shockproof packaging and the design method of corrugated boxes, and in addition, follow relevant standards. For example, the packaging of export commodities should meet international standards or the requirements of foreign investors, and should pass relevant tests. Therefore, it is not easy to choose the right corrugated box.
1. The corrugated models of corrugated paperboard can be divided into four categories: A, B, C and E according to the height of the corrugated board. The mechanical properties of different corrugated boards are also different. Type A corrugated paperboard has the highest plane pressure and higher compressive strength, while type B corrugated paperboard has the opposite. Type C corrugated paperboard has better plane pressure, vertical pressure, parallel pressure and buffer force; The thickness between corrugated boards is the largest in Type A, followed by Type C, followed by Type B, followed by Type E, which is the smallest. Because it is easier to process and bend cardboard with small thickness, Type B corrugated paper is widely used for packaging and transportation of boxes that do not require high compressive strength. According to the different mechanical properties of corrugated board, type A or type C is preferred for single-sided corrugated boxes, type A, type B or type B and type C are preferred for double-sided corrugated boxes, and type B is preferred for those close to the outer surface, which can play an impact resistance role. Type A, B or B, C can be combined to improve the physical and mechanical properties of the carton; In terms of printability, both type B and type C are favorable for printing.
2. On the premise of ensuring the quality of cartons, the processing materials and packaging costs of cartons should be saved as much as possible. For example, for cartons with the same volume, the length: width: height of 2:1:2 is the most economical, and the ratio of 1:1:1 is the most expensive. Therefore, the square design shall be avoided as far as possible, and the utilization ratio of the product to the carton volume, the utilization ratio of the carton to the truck and train carriage volume, and the stability of the stacking during storage, transportation and pumping shall also be considered.
