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(lèi)。

The processing technology of heavy cartons is mainly divided into two categories.

1、全自動(dòng)重型包裝紙箱生產(chǎn)線生產(chǎn)工藝

1. Production technology of automatic heavy packaging carton production line

該重型包裝紙箱生產(chǎn)工藝應(yīng)用得比較廣泛，具有生產(chǎn)批量大、紙箱成型體積較大、楞型質(zhì)量好等優(yōu)點(diǎn)。該工藝生產(chǎn)出來(lái)的重型包裝紙箱，通常是通過(guò)水性印刷、開(kāi)槽、粘糊、成型等工序制成紙箱的。以這種工藝生產(chǎn)出的紙箱主要用做運(yùn)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(dòng)重型包裝紙箱生產(chǎn)線生產(chǎn)工藝

2. Production technology of semi-automatic heavy packaging carton production line

該重型包裝紙箱生產(chǎn)工藝是先印刷面紙，再與起好的瓦楞芯紙、紙板進(jìn)行裱合。該工藝生產(chǎn)出來(lái)的重型包裝紙箱，常規(guī)采用模切壓痕、粘釘?shù)裙ば虺上洹Ｔ摴に嚿a(chǎn)出的紙箱成型質(zhì)量好、表面處理效果好。以折中工藝生產(chǎn)出的紙箱可用做銷(xiāo)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(guī)紙箱印刷方式

2、 Conventional carton printing method

常規(guī)紙箱印刷方式主要有柔印、膠印和網(wǎng)印三種。柔性版印刷重型包裝紙箱，常規(guī)的柔性版印刷重型包裝紙箱工藝是直接在重型紙箱上進(jìn)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(diǎn)：

Flexographic direct printing has the following characteristics:

1)幅面大，寬幅的柔性版印刷機(jī)幅寬可達(dá)到2.5~2.8m.

1) The width of flexographic printing press with large format can reach 2.5 ~ 2.8m.

2)低，柔性版耐印力很高，可重復(fù)使用;幽默也較低。

2) The price is low, the flexographic printing resistance is very high, and can be reused; Humor is also cheap.

3)可以聯(lián)動(dòng)生產(chǎn)，如印刷、開(kāi)槽、壓痕、訂(粘)箱、打捆等一機(jī)即可完成。

3) Can linkage production, such as printing, slotting, indentation, ordering (gluing) boxes, baling and so on.

4)紙箱強(qiáng)度降低比較少。由于柔印是輕壓印刷，所以對(duì)重型包裝紙箱的強(qiáng)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(guī)膠印加網(wǎng)線數(shù)為175線/英寸，而柔印紙箱常規(guī)加網(wǎng)線數(shù)字有35~65線/英寸，屬于低精度印刷方式，更適合印刷文字線條稿，四色圖像印刷質(zhì)量進(jìn)年來(lái)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.
