UN纸箱有什么用，有哪些优点？
简单的来说，UN箱--危险品包装的通行证=安全（通行证适用于空运海运等出口运输方式）
一般是由瓦楞纸箱做成的，瓦楞纸想拥有优良的抗压、抗戳穿和防潮性能，对商品的保护性能很强，且其具有很好的密闭性，它适合于危险货物的包装。
所以你千万不能小看这个小小的纸箱，它是有多层瓦楞硬纸板做成的，经过特殊的生产加工处理，
，有很强的防潮性能。在南方，要是遇到回南天的潮湿天气，放一个月它都不会湿。（这性能非常适合4类的易燃固体，遇水容易自燃的危险品）。
第二，它的抗压、密闭性非常好。我们知道，在运输过程中，避免不了搬搬抬抬，箱子经受不住考验，容易发生泄漏和污染，所以箱子的硬度和密闭性能高在运输过程中显得至关重要，一个大尺寸的UN BOX,封箱后一个成年人站在上面也不会变形，可见它的坚硬程度了。
第三，它非常轻，可根据货物的重量，大小选择合适的尺寸。不会增加货物的重量或体积，像给货物打个木箱，在危险品包装里都是常见的，但是坏处是会增加十几斤重量啊，又或者泡沫箱包装，也可能会造成体积过大。产生更多的运输费用。
What are the uses and advantages of UN cartons?
Simply put, UN box - pass for dangerous goods packaging = safety (pass is applicable to export transportation modes such as air and sea transportation)
It is generally made of corrugated boxes. Corrugated paper has excellent compression resistance, puncture resistance and moisture-proof performance, strong commodity protection performance and good airtightness. It is suitable for the packaging of dangerous goods.
So you must not underestimate this small carton. It is made of multi-layer corrugated cardboard and has been specially processed,
, with strong moisture resistance. In the south, if you encounter the humid weather back to the south, it won't get wet for a month. (this property is very suitable for class 4 flammable solids and dangerous goods that are prone to spontaneous combustion in case of water).
Second, its compression resistance and airtightness are very good. We know that in the process of transportation, we cannot avoid lifting. The box can not stand the test and is prone to leakage and pollution. Therefore, the high hardness and sealing performance of the box are very important in the process of transportation. A large UN box will not deform when an adult stands on it after sealing, which shows its hardness.
Third, it is very light. You can choose the appropriate size according to the weight and size of the goods. It will not increase the weight or volume of the goods. For example, it is common to pack the goods in wooden cases, but the disadvantage is that it will increase the weight by more than ten kilograms. Or the foam box packaging may also cause the volume to be too large. Generate more transportation costs.
