Container Processing and Shape Design II

Using a twisting machine, bending machine, punching machine and other machinery according to the shape of the box, the knife line is cut off, bent or bent into various angles.

The height of the cross cutting line is 23.8 mm and the thickness is 0.7 mm. The die cutting lines embedded in the die plate must be of the same height. The height and thickness of the crease line depends on the thickness of the paper. The crease line height is the height of the die cut line minus the thickness of the paper.

After the knife line is inserted, apply foam rubber on both sides so that the cardboard can be ejected from the die plate, as shown in Figure 8-32.

7 Making Die-Cut Yin Jian Yin Jian is to obtain a good seam, paste the insulating paper on the steel plate, put it into the machine, put the carbon paper, and then cover a layer of cardboard, start the machine to press to get the indentation, in the pressure A crease groove is made in the mark.

(2) Die-cutting and creasing machine

A die-cutting machine is generally a flat-pressure type, capable of automatic paper feeding, automatic die cutting, and automatic paper feeding, and generally has a speed of 1,800-3,600 pieces/hour. External die-cutting electronic control device with speed up to 8500 sheets/

, and can automatically clear the waste edge.
In addition to die cutting, die-cutting and creasing machines can also be used for cold-pressing and embossing, hot-pressed flat bump aluminum and hot-pressed bumps.

5. Make box

The box-making machine is folded into a box for use in the next process.

Corrugated cartons are generally printed with a flexographic printing plate, and they are pressed, brushed, or set with iron wire to form the shape of a box. Generally, the box is folded and rotated. When used, it is opened into a box shape.

Flexible packaging

With increasing flexible packaging, single flexible packaging materials have poor protection for interior contents. Therefore, composite materials are now used to make bags and seal the contents.

The production process is: printing → compound → cutting → bag making.

Substrate materials generally have plastic film, paper or aluminum foil.

Most of the printing uses gravure printing, but also use flexographic printing.

The composite extruder is bonded to hot-melt polyethylene or various types of laminators are used to bond the film and film together. The specific compounding method and materials used are determined according to the requirements of the contents.

Cutting, according to the direction of rewinding, connected in a row to cut off.

Bags are made in various forms, as shown in Figure 8-33. There are a variety of methods for the adhesion of bags, such as adhesives, hot stamping, pulse sealing, high-frequency sealing, super-wave sealing, and the like.
