At present, most of the heavy-duty carton structures on the market are the box structure of the sky and earth cover type, because the structure of the sky and earth cover type is more convenient and simple in use or operation. When you need to load the product, you can directly put the enclosure well, and then the product can be directly covered and packed. It takes only a few minutes for a set of packaging to come down. Here I will explain to you. There are two points to be noted

1.偷工減料。

1. Cut corners.

一般在定制重型紙箱時廠家會給你各式各樣的內托，而這些內托有可能是EVA珍珠綿也有可能是蜂窩紙內襯材料，有時候是根據所需包裝產品特性來決定，容易出現問題的關鍵就在于這里的內托，并不是說這個內托怎么樣，而是內托掩蓋住的部分，我們常規所熟知的圍邊天地蓋重型紙箱都是有一個紙板框框圍住，形成一個正方形圍欄一樣的東西，再通過外面一層紙板，形成一個外面的圍邊。

Generally, when you customize heavy-duty cartons, manufacturers will recommend a variety of inner brackets. These inner brackets may be EVA pearl wool or honeycomb paper lining material. Sometimes they are decided according to the characteristics of the packaging products required. The key to problems is the inner bracket here. It's not the inner bracket, but the part covered by the inner bracket, The heavy-duty cartons that we usually know are surrounded by a cardboard frame to form a square fence like thing, and then through a layer of cardboard outside to form an outside fence.

底就是后來往上包的那塊紙板的部分，但是有的工廠為了偷工減料在里面的內框正方形的紙板上動手腳，為了維持圍邊內部框框的高度，會減少他紙板的寬，在和圍邊成型的時候，用些軟體的內材料，墊著，然后把框框放在這些軟體內托上，維持高度再進行圍邊，圍邊完成之后再把這個內材料抽出，這樣做就達到了紙張成本減少的目的

The bottom is the part of the cardboard that was later wrapped up. However, in order to cut corners, some factories use their hands and feet on the square cardboard inside the inner frame. In order to maintain the height of the inner frame around the edge, they will reduce the width of the cardboard. When forming with the edge, they use some soft inner material to pad it, and then put the frame on these soft inner brackets to maintain the height, and then surround the edge, The inner material is pulled out after the edge is finished, so as to achieve the purpose of reducing the paper cost

2.膠水問題

2. Glue problem

還有一種情況就是沒有偷工減料的情況下，他們所用的膠水，質量可能也不大好，這樣就造成一個比較嚴重的問題，重型紙箱的圍套有可能出現裂痕或者是脫落，怕的情況，還是出現圍套框不在同一水平線上，這樣很容易會導致內箱的四個角出現不同程度的撕裂，因為運輸這些過程很有可能導致這些內箱本來就不平整的角度出現問題，所以盡可能驗貨的時候，打開內托看看圍套內部框框是不是緊貼著底層紙板，不然的話你會大失所望哦

Another situation is that without cutting corners, the quality of the glue they use may not be good, which causes a serious problem. The heavy-duty carton may have cracks or fall off. In case of fear, the frame of the heavy-duty carton may not be on the same horizontal line, which may easily lead to different degrees of tearing at the four corners of the inner carton, Because the transportation process is likely to lead to problems in the uneven angle of these inner boxes, when inspecting the goods as far as possible, open the inner bracket to see if the inner frame of the enclosure is close to the bottom cardboard, otherwise you will be greatly disappointed
