How can express boxes reduce the breakage rate through structural design?

To reduce the breakage rate of express boxes through structural design, it is necessary to start from multiple dimensions such as material selection, box structure, buffer design, and sealing method. The following is a specific analysis:In terms of material selection, corrugated cardboard is the mainstream material of express boxes, and its thickness and number of layers have a significant impact on strength. Three-layer corrugated cardboard is suitable for small and medium-sized lightweight items, such as cosmetics, puffed foods, etc., with low cost and can meet basic protection needs; five-layer and above corrugated cardboard has higher compressive strength and stacking strength, suitable for medium and large or heavy goods, such as home appliances, books, etc. For example, an express box using five-layer BE corrugated cardboard (double-corrugated paper) has a combination of two layers of corrugated paper core and interlayer, face paper, and lining paper, which has stronger rigidity, higher hardness, better impact resistance, and can effectively reduce the risk of damage during transportation.In terms of box structure design, reasonable size planning is crucial. The volume, weight, shape and ergonomic principles of the goods need to be comprehensively considered to avoid human fatigue or reduced transportation efficiency due to improper size of the carton. At the same time, appropriate buffer space should be reserved during design to prevent the goods from shaking and colliding in the box. For some special-shaped goods, customized packaging can be used to ensure that all parts are well protected.Buffer design is the key link to reduce the breakage rate. Adding fillers such as bubble film, foam particles, paper balls, etc. in the box can effectively absorb the impact during transportation. For fragile items, double-layer packaging can be used, with hard cartons on the outer layer and bubble bags or foam and other buffer materials on the inner layer for all-round protection. For example, fragile goods such as glassware and ceramic products can be greatly reduced in the possibility of breakage even if they are squeezed or collided during transportation after double-layer packaging.The sealing method also affects the strength of the express box. Use high-strength tape for sealing to ensure that the tape and the carton are firmly bonded to avoid the cracking of the tape during transportation and the carton falling apart. At the same time, the sealing parts are reasonably designed, such as forming gaps at the top and bottom edges of the carton, and the stability of the sealing is enhanced through the mutual engagement between the bottom plates, the friction between the plates, and the cooperation of the sealing device.In addition, the corners and edges of the carton can also be reinforced, such as adding corner guards or reinforcing ribs, to improve the pressure resistance of these vulnerable parts. Some express boxes use reinforced structures at the four corners and bottom, which can effectively disperse the pressure and reduce the damage caused by excessive local force.By optimizing material selection, rationally designing the box structure, improving the buffer design, and improving the sealing method, the express box can significantly reduce the breakage rate, ensure the safety of goods during transportation, and improve logistics efficiency and customer satisfaction.
