New printing carton way technology analysis

1. When the plastic gravure compound carton process adopts single-faced corrugated production line,

After the printing is completed, it is still necessary to cover the bright film, and if the production volume is large, it may not be

Paper is printed on the sheet, and gravure is used to complete the gravure printing on the plastic film.

On the white background, the printed plastic film is first compounded with the face paper, and then the conventional carton is

Forming process to complete the box. The characteristics of this process are:

(1) The cost of carton production is low. When the production volume is large, this process can be large

Greatly reduce the printing cost of facial paper and the material cost of facial paper. Because the paper does not need to be printed

Brushes, which can be used non-coated white paper, so that the cost of paper is greatly reduced.

(2) beautifully printed. Because it is a plastic gravure, the printing effect can be

Offset printing is comparable. The use of this process requires special attention in the printing process

In the meantime, fully consider the dimensional change and deformation of the plastic film; otherwise, carton paper

It will be misaligned with the lower cardboard.

2. Coated paper gravure composite carton process when the production volume is relatively large, do not need to cover

The film can be used when it requires good printing effect and low cost. The process

The first is to use a paper gravure printer to print thinner coated paper, and then apply this finely printed copper.

Plates are compounded with ordinary slagboard or linerboard, and the whole is used as cartonboard, and then

Pairing and normal carton forming. The characteristics of this process are:

(1) The cost of carton production is low. The main reason for the cost reduction is to change the whiteboard paper

The combination of low-weight coated paper and low-cost linerboard reduces material costs.

(2) beautifully printed. Paper gravure printing is very beautiful.

(3) Gravure plate making is more complicated and costly, and it is not suitable for printing.

Carton products.

(4) Operation and control methods for printing process, such as face-to-face paper compounding and box making

It is necessary to carefully explore, accumulate, and implement it rationally, otherwise it will easily lead to a rise in scrap rates.

high.

3. Direct offset printing corrugated box process Corrugated box direct offset printing process currently in the country

The outside is more mature, it is the corrugated board directly on a special offset press

print. Suitable for processing thin corrugated boxes.

The process can not only ensure the good moldability of the carton, but also can complete the exquisite face paper printing

Brush, but the price of the printing press used is relatively expensive, and the current demand standard with our country

Not quite suitable for the carton industry in the near future, but in the coming years,

This process may become a new direction for the development of high-end carton printing in China.

4. Flexo preprinted and gravure preprinted corrugated box processes

Faster development this year, both of these processes are first printed on web

Face paper, and then complete the production of corrugated board in the automatic corrugated board production line.

Carton printing quality and molding quality are relatively high, but the investment is relatively large and it is not suitable

In small batch production.

In the domestic carton industry, three conventional corrugated carton printing methods are applied

More generally, it has become the mainstream method of corrugated box printing. The new printing system

Box mode, because the hot spots of equipment, materials, processes, operations and other technologies have not been completed

Full control, investment is relatively large, promotion is still relatively large. But the carton company

In order to improve the quality, reduce the total cost of the carton, get the maximum profit, increase in

With the competitive advantage in the market, it is imperative to adopt a new type of printing box technology.

From the general development of the carton printing process, the flexographic printing of corrugated paper directly

The process of plate making and printing in box technology needs to be improved as a whole. Plastic gravure printing and carton gravure printing

, web offset printing process to be promoted and improved, direct offset and pre-printed corrugated boxes

The production process should also draw our attention.
