貨物外徑和武漢重型紙箱的內徑和外徑。需要滿足以下關系。重型紙箱的外徑等于重型包裝紙箱內徑兩個瓦楞紙板的厚度。在設計中，大多數瓦楞紙板都是通過壓線彎成U形或L形的。有時它們由兩條高壓線路組成，分別是模切或壓平。這種彎曲變化使瓦楞紙板的展開尺寸成為瓦楞紙箱設計的基本尺寸。設計的基本概念和基本附加尺寸。
The outer diameter of the goods and the inner diameter and outer diameter of Wuhan Heavy carton. The following relationships need to be met. The outer diameter of the heavy carton is equal to the inner diameter of the heavy packing carton and the thickness of two corrugated boards. In the design, most corrugated boards are bent into U-shape or L-shape by pressing lines. Sometimes they are composed of two high and low voltage lines, which are die-cut or flattened. This bending change makes the unfolding size of corrugated board become the basic size of corrugated box design. Basic concepts and basic additional dimensions of design.
重型紙箱的加工工藝主要分為兩類。
The processing technology of heavy cartons is mainly divided into two categories.
1、全自動重型包裝紙箱生產線生產工藝
1. Production technology of automatic heavy packaging carton production line
該重型包裝紙箱生產工藝應用得比較廣泛，具有生產批量大、紙箱成型體積較大、楞型質量好等優點。該工藝生產出來的重型包裝紙箱，通常是通過水性印刷、開槽、粘糊、成型等工序制成紙箱的。以這種工藝生產出的紙箱主要用做運輸包裝。
The heavy packing carton production process is widely used, and has the advantages of large production batch, large carton forming volume, good corrugated quality and so on. The heavy packaging cartons produced by this process are usually made into cartons through water-based printing, slotting, pasting, molding and other processes. The cartons produced by this process are mainly used for transportation packaging.
2、半自動重型包裝紙箱生產線生產工藝
2. Production technology of semi-automatic heavy packaging carton production line
該重型包裝紙箱生產工藝是先印刷面紙，再與起好的瓦楞芯紙、紙板進行裱合。該工藝生產出來的重型包裝紙箱，常規采用模切壓痕、粘釘等工序成箱。該工藝生產出的紙箱成型質量好、表面處理效果好。以折中工藝生產出的紙箱可用做銷售包裝。
The production process of the heavy packaging carton is to print face paper first, and then mount it with corrugated core paper and paperboard. The heavy packing cartons produced by this process are usually packed into boxes through die-cutting, indentation, nail sticking and other processes. The carton produced by this process has good forming quality and good surface treatment effect. The cartons produced by the compromise process can be used as sales packaging.
二、常規紙箱印刷方式
2、 Conventional carton printing method
常規紙箱印刷方式主要有柔印、膠印和網印三種。柔性版印刷重型包裝紙箱，常規的柔性版印刷重型包裝紙箱工藝是直接在重型紙箱上進行印刷，使用的是水基油墨，因此也有人將該工藝為水印。
Conventional carton printing methods mainly include flexo printing, offset printing and screen printing. Flexographic printing heavy-duty packaging carton. The conventional flexographic printing heavy-duty packaging carton process is to print directly on the heavy-duty carton, using water-based ink. Therefore, some people also use this process as a watermark.
柔性版直接印刷具有如下特點：
Flexographic direct printing has the following characteristics:
1)幅面大，寬幅的柔性版印刷機幅寬可達到2.5~2.8m.
1) The width of flexographic printing press with large format can reach 2.5 ~ 2.8m
2)，柔性版耐印力很高，可重復使用;幽默也較。
2) The price is low, the flexographic printing resistance is very high, and can be reused; Humor is also cheap.
3)可以聯動生產，如印刷、開槽、壓痕、訂(粘)箱、打捆等一機即可完成。
3) Can linkage production, such as printing, slotting, indentation, ordering (gluing) boxes, baling and so on.
4)紙箱強度降比較少。由于柔印是輕壓印刷，所以對重型包裝紙箱的強度影響很少。
4) The strength of cartons is reduced less. As flexo printing is light pressure printing, it has little effect on the strength of heavy packaging cartons.
5)印刷精度不高，常規膠印加網線數為175線/英寸，而柔印紙箱常規加網線數字有35~65線/英寸，屬于精度印刷方式，更適合印刷文字線條稿，四色圖像印刷質量進年來雖有提高，但仍有局限。
5) The printing accuracy is not high. The number of conventional offset screen lines is 175 lines / inch, while the number of conventional screen lines of flexographic cartons is 35 ~ 65 lines / inch. It belongs to a low-precision printing method, which is more suitable for printing text line manuscripts. Although the printing quality of four-color images has been improved in recent years, it is still limited.
6)制版有易有難，文字線條稿制版容易，四色圖像制版難度較大。
6) Plate making is easy and difficult, text line draft plate making is easy, and four-color image plate making is more difficult.
