货物外径和武汉重型纸箱的内径和外径。需要满足以下关系。重型纸箱的外径等于重型包装纸箱内径两个瓦楞纸板的厚度。在设计中，大多数瓦楞纸板都是通过压线弯成U形或L形的。有时它们由两条高压线路组成，分别是模切或压平。这种弯曲变化使瓦楞纸板的展开尺寸成为瓦楞纸箱设计的基本尺寸。设计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.
重型纸箱的加工工艺主要分为两类。
The processing technology of heavy cartons is mainly divided into two categories.
1、全自动重型包装纸箱生产线生产工艺
1. Production technology of automatic heavy packaging carton production line
该重型包装纸箱生产工艺应用得比较广泛，具有生产批量大、纸箱成型体积较大、楞型质量好等优点。该工艺生产出来的重型包装纸箱，通常是通过水性印刷、开槽、粘糊、成型等工序制成纸箱的。以这种工艺生产出的纸箱主要用做运输包装。
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、半自动重型包装纸箱生产线生产工艺
2. Production technology of semi-automatic heavy packaging carton production line
该重型包装纸箱生产工艺是先印刷面纸，再与起好的瓦楞芯纸、纸板进行裱合。该工艺生产出来的重型包装纸箱，常规采用模切压痕、粘钉等工序成箱。该工艺生产出的纸箱成型质量好、表面处理效果好。以折中工艺生产出的纸箱可用做销售包装。
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、常规纸箱印刷方式
2、 Conventional carton printing method
常规纸箱印刷方式主要有柔印、胶印和网印三种。柔性版印刷重型包装纸箱，常规的柔性版印刷重型包装纸箱工艺是直接在重型纸箱上进行印刷，使用的是水基油墨，因此也有人将该工艺为水印。
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点：
Flexographic direct printing has the following characteristics:
1)幅面大，宽幅的柔性版印刷机幅宽可达到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，可重复使用;幽默也较。
2) The price is low, the flexographic printing resistance is very high, and can be reused; Humor is also cheap.
3)可以联动生产，如印刷、开槽、压痕、订(粘)箱、打捆等一机即可完成。
3) Can linkage production, such as printing, slotting, indentation, ordering (gluing) boxes, baling and so on.
4)纸箱强度降比较少。由于柔印是轻压印刷，所以对重型包装纸箱的强度影响很少。
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，常规胶印加网线数为175线/英寸，而柔印纸箱常规加网线数字有35~65线/英寸，属于精度印刷方式，更适合印刷文字线条稿，四色图像印刷质量进年来虽有提高，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)制版有易有难，文字线条稿制版容易，四色图像制版难度较大。
6) Plate making is easy and difficult, text line draft plate making is easy, and four-color image plate making is more difficult.
