Selection principle of stone corrugated cardboard box
In the selection of corrugated cartons, the company should first take into account the nature, weight, storage and transportation conditions and the circulation environment. Secondly, it should be designed according to the design principle of shockproof packaging and the design method of corrugated cardboard box. In addition, the relevant standards should be followed, such as the export commodity packaging should conform to the international standards or the requirements of foreign businessmen. Therefore, general attention should be paid to the following two points when choosing corrugated boxes.
Stone block, corrugated box, quartz stone corrugated box, mosaic glass sample box, artificial stone box XW001
1 corrugated corrugated corrugated models are classified into four categories according to their height: A, B, C and E. The mechanical properties of corrugated cardboard are also different.
The plane pressure of A corrugated cardboard is high, the compressive strength is larger, the B type is the opposite, the plane pressure, the vertical pressure, the parallel pressure and the buffer force of the C type are better. The thickness of the corrugated cardboard, the A type, the C type, the B type again, the E is the smallest, and the paperboard with small thickness is easy to bend, so the B shaped corrugated paper is widely used. It is widely used in packing boxes for low pressure strength of boxes.
According to the different mechanical properties of corrugated cardboard, the single side corrugated cartons are A or C, and the double sided corrugated cartons are combined with A, B type or B and C type, and the use of B type near the outer surface can play an anti impact effect. The combination of A, B or B and C can improve the physical and mechanical properties of cartons. Compared with printability, B and C are beneficial to printing.
2. The cartons of stone tiles and cartons should save carton processing materials and packaging costs as much as possible to ensure the quality of cartons.
For example, the volume of the same carton, long: width: high 2:1:2, the most saving material, the ratio of 1:1:1 is the most expensive material. Therefore, we should avoid using the square box as much as possible, and take care of the utilization of the volume of the box, the utilization of the volume of the truck, the train carriage and the stability of the stacking during the storage and transportation.
