What is heavy carton? Is this carton very heavy? No, the cartons that are relatively wear-resistant, have strong compression resistance of empty cartons and can bear heavy load are called heavy cartons. Most heavy cartons now weigh between a few hundred pounds and a few tons. Yes, you heard me right. So, this heavy carton has not been tested and used. How can we know its carrying capacity? Here is a small formula, which I won't tell ordinary people. Come and have a look. There are two steps to calculate the carrying capacity of heavy cartons. The first step is to know the area of cartons. Then calculate the weight per unit area. We should be very familiar with the calculation of the area of the cartons. I won't talk about it here. It's mainly about the calculation of the load of the cartons.

　　如AB槽:紙面紙基重+B槽基重*瓦楞紙箱率+芯紙基重+A槽基重*瓦楞紙箱率+基重=紙箱承載能力。這是多層瓦楞紙箱的計算方法，如果是單坑瓦楞紙箱，可計算為:紙面基重+瓦楞紙基重*瓦楞率+底紙基重=單坑紙箱基重。而在計算紙箱承載時，瓦楞率是前提，一般A槽=1.51,B槽=1.36,C槽=1.44,E槽=1.31,F槽=1.23。但是每個廠家使用的瓦楞輥的規(guī)格不同，所以瓦楞率也會不同。當然，重載紙箱的承載力計算與實際承載力會有很多次偏差，造成計算誤差的原因，也是由于含水率的偏差造成的。但偏差不會太大，一般在5% - 10%之間。

　　For example, AB slot: paper base weight + B slot base weight * corrugated box rate + core paper base weight + a slot base weight * corrugated box rate + base weight = carton carrying capacity. This is the calculation method of multi-layer corrugated box. If it is a single pit corrugated box, it can be calculated as: paper base weight + corrugated base weight * corrugated rate + bottom paper base weight = single pit box base weight. In the calculation of carton load, the corrugated rate is the premise. Generally, slot a = 1.51, slot B = 1.36, slot C = 1.44, slot e = 1.31, slot f = 1.23. But the specifications of the corrugating roller used by each manufacturer are different, so the corrugating rate will be different. Of course, there will be many deviations between the calculation of the bearing capacity of heavy-duty cartons and the actual bearing capacity, which is also caused by the deviation of moisture content. But the deviation is not too large, generally between 5% - 10%.

　　重型紙箱正是因為它能承受更大的重量，具有更好的耐磨性，可以為各種包裝產(chǎn)品服務(wù)，其是普通的可回收再利用，受到大眾的歡迎。

　　Heavy duty carton is just because it can bear more weight, has better wear resistance, can serve for all kinds of packaging products, its price is common recyclable, and is popular with the public.
