How much do you know about the basic process of a carton production?

In daily life, the application of cartons is very extensive. Daily packaging, transportation, storage, etc. will be applied to cartons. What processes do the cartons go through? The following editor of Shenzhen Intercon Pack Co.,Ltd. will introduce you in detail

1: The required raw materials and production equipment

Raw paper and corrugated paper, carton production machines, rubber plates, printing machines, nailing machines, etc.

2: Production steps

1) Purchase base paper and corrugated paper.

Some factories have strong production capacity and can directly purchase wood to produce base paper on their own. The general carton factory purchases cardboard directly to make the carton, and the secondary carton factory processes the cardboard by itself, saving costs.

2) Make cardboard as required.

The base paper is also divided into good and bad, and the grammage is different. Corrugated paper is also divided into three types: A, B, and C. Corrugated paper refers to the wave-like paper in the middle of the kraft paper. The corrugated paper has high and low. At the same time, the carton has three layers and five layers. Three layers means one layer of corrugated paper, and five layers means two layers of corrugated paper.

3) After the customer places an order, the area and price must be calculated.

Take the ordinary carton as an example. As long as you know the length, width and height of the carton, you can calculate the area. When calculating the total length, you need to calculate the glued part (about 2-3 cm), which depends on the company's internal requirements.

4) Attached drawing paper, first make a rubber template according to the drawing.

Carton boxes generally have printing requirements, so they must be attached with drawings, and the color and customer requirements must be indicated on the drawings. Then the rubber plate will be made by the staff in the printing room as required. Generally, ink printing is relatively simple, and the fonts and colors are not as complicated as offset printing, and they are very simple.

5) Prepare the ink and debug the machine, you can start printing on the machine.

Put the template on the machine and confirm the length and width dimensions. First, take out a few sheets to see the effect. One is to see if the size is correct, and the other is to see if the printing effect is satisfactory.

6) Carton forming. That is, the workers glue the cartons or nail the cartons.

Allowing an extra 2-3 cm before is the key to carton forming. If it is glued, you can't hit more or less when you glue it. If it hits too much, it will stick to the surface of other cartons. If it's glued, it won't stick.

7) Packing.

After the carton is formed, depending on the size of the carton, tie it with packing straps in a bundle of 5 or 10 and set it aside. Now there are automatic or semi-automatic packing machines for packing, which is simple and convenient.

Matters needing attention when printing

When printing, be sure to check the drawings. Printing is a very error-prone link.
