At a time when the logistics industry is booming, ordinary carton, as the most commonly used packaging container, has always been a concern about its breakage during transportation. Damage to ordinary carton may not only cause damage to the goods, but also increase logistics costs and corporate losses. Through scientific and reasonable design, the breakage rate of ordinary carton in logistics transportation can be effectively reduced to ensure the safe delivery of goods.
Reasonable ordinary carton structure is the basis for reducing the breakage rate. First of all, it is crucial to choose the right box type. Common ordinary carton box types include butt-joint boxes, nested boxes, folding boxes, etc. Butt-joint boxes have become a common choice for logistics transportation because of their convenient opening and closing and good stacking stability; the structure of nested boxes with upper and lower separation can provide stronger protection and is suitable for fragile items. Secondly, strengthening the corner structure design of ordinary carton, by adding corner guards or using double corrugated cardboard to reinforce the corners, can effectively disperse external impact forces and avoid corners from being damaged due to collision. In addition, optimizing the swing cover design of ordinary carton and appropriately increasing the width and overlap of the swing cover can enhance the sealing and overall strength of the box and prevent the box from being deformed or cracked due to extrusion during transportation.
Material quality directly affects the damage resistance of ordinary carton. In the selection of cardboard, high-strength and high-toughness corrugated cardboard is preferred. The type of corrugation (such as A, B, C, E, etc.) and the number of layers will significantly affect the performance of ordinary carton. For example, B-type corrugation has high density and flat surface, which is suitable for printing but has slightly weak cushioning; A-type corrugation has good cushioning performance and is suitable for packaging heavy or fragile items. According to the weight of the goods and transportation requirements, the type and number of corrugations should be reasonably selected. For example, for goods that are heavy and easy to collide, AB or BC double-layer corrugated cardboard can be used. At the same time, ensure that the ring crush strength, burst resistance and other indicators of the base paper meet the standards to avoid the ordinary carton from being easily damaged during transportation due to poor material quality.
If the printing process on the surface of ordinary carton is not reasonable, its strength may be weakened. Try to reduce full-page printing and dark printing, because a large amount of ink coverage will make the cardboard absorb water and soften, reducing the compressive strength. Use water-based ink for printing, which is environmentally friendly and has less effect on the strength of the cardboard than solvent-based ink. In terms of printing position arrangement, avoid large-scale printing on the load-bearing parts of ordinary carton (such as the bottom and corners) to prevent the strength of these key parts from decreasing due to printing. In addition, control the printing pressure to avoid crushing the corrugated structure due to excessive pressure, which will affect the overall compressive performance of ordinary carton.
In order to prevent the goods from shaking and colliding in ordinary carton and causing damage to ordinary carton, a reasonable internal buffer and fixed structure must be designed. For fragile items, cushioning materials such as pearl cotton, foam board, and bubble film can be added to the box to separate the goods from the inner wall of ordinary carton and absorb impact. Use corrugated cardboard to make internal partitions or pads, customize the design according to the shape of the goods, fix the goods in a specific position, and restrict their movement. For example, when transporting bottled products, use corrugated cardboard to make honeycomb partitions to separate and fix the bottles, reduce mutual collisions, and reduce the impact of external impact on ordinary carton.
A humid environment will seriously reduce the strength of ordinary carton and increase the risk of damage. Moisture-proof treatment on the surface of ordinary carton, such as applying moisture-proof oil, laminating, etc., can effectively prevent moisture intrusion. For long transportation time and high environmental humidity, desiccant can also be placed inside ordinary carton. In addition, choose corrugated cardboard with moisture-proof properties, such as adding moisture-proof agent to base paper, or using waterproof adhesive to make corrugated cardboard, to improve the moisture-proof ability of ordinary carton from the material level, ensure that it can still maintain sufficient strength in a humid environment, and reduce damage caused by moisture softening.
In logistics transportation, ordinary carton needs to undergo multiple stacking and handling. Reasonable design of easy-to-operate structure can reduce damage. Design handles or buckles for easy handling to avoid directly pulling the corners of ordinary carton during handling and reduce the risk of tearing. Optimize the stacking design of ordinary carton to ensure that the surface of the box is flat and the edges and corners are clear, so that the ordinary carton is evenly stressed when stacked, and it is not easy to collapse, squeeze and break due to unstable center of gravity or uneven stress. At the same time, mark clear handling signs on the surface of ordinary carton, such as "fragile", "upward", "stacking limit", etc., to remind logistics personnel to standardize operations and reduce damage to ordinary carton caused by improper handling.
After completing the design of ordinary carton, testing by simulating the logistics transportation environment is a key step to find problems and optimize the design. Use compression testing machines, drop testing machines and other equipment to test the compression, drop, vibration and other performance of ordinary carton, simulate various external forces during transportation, and detect the weak links of ordinary carton. According to the test results, adjust the design plan in a targeted manner, such as strengthening the easily damaged parts, optimizing the structural parameters, etc., and repeatedly test and optimize until the performance of ordinary carton meets the requirements of logistics transportation and minimizes the breakage rate in actual transportation.
Through the above design optimization from structure, material, process to testing, the damage resistance of ordinary carton in logistics and transportation can be significantly improved, providing reliable guarantee for the safe transportation of goods and reducing logistics losses and costs.
