When choosing corrugated boxes, we first need to consider the nature, weight, storage and transportation conditions and circulation environment of the product. Next, we need to design according to the design principle of shock-proof packaging and the design method of corrugated boxes. In addition, we need to follow relevant standards. For example: the packaging of export commodities needs to comply with international standards or foreign business requirements, and relevant testing is also required. Therefore, what should be paid attention to when choosing corrugated box packaging?
1. On the corrugated model, it is first necessary to divide it into four types: A, B, C, and E according to the height of the corrugated board, and for different corrugated cardboard, its mechanical properties will also be different. For example: the plane pressure of the corrugated cardboard of type A is high, so it is also relatively large in compressive strength, the opposite is the case for type B, and the plane pressure, vertical pressure, parallel pressure and buffer of type C are The strength is better; there is also the thickness between the corrugated cardboard, which belongs to the A-type, followed by the C-type, B-type, and the E-type, but because the thickness of the cardboard is small in the processing bending Therefore, the B-shape is mainly used in packaging and shipping boxes that do not require high compressive strength of the box. According to the different mechanical properties of corrugated cardboard, it is better to use type A or C for single-sided corrugated boxes, while it is better to use type A, B or a combination of types B and C for double-sided corrugated boxes, but it is close to the outside. The surface is better to use B type, so that it can play a role in impact resistance. The combination of type A, B or type B and C can improve the physical and mechanical properties of the carton; in terms of printability, type B and type C are both conducive to printing.
2. In terms of the box shape of the corrugated carton, it is necessary to save the processing materials and packaging costs of the carton as much as possible on the premise of ensuring the quality of the carton. For example, on the same volume of cartons, we can use the ratio of length: width: height in 2:1:2 to save material, and when the ratio is 1:1:1, it costs material. Therefore, to avoid the use of square boxes as much as possible, it is also necessary to consider the utilization rate of the product to the box volume, as well as the utilization rate of the box to the volume of trucks and train cars, and the stability of stacking during storage and transportation.
