4, three-side sealing equipment standard:

Printing equipment: gravure printing (commonly known as copper plate) printing, full computer-controlled printing machine, can print 1-8 colors.

Composite equipment: a fully computer-controlled composite device with multiple layers of composite.

The tension of the three-side bag sealing machine has to unwind tension, longitudinal sealing tension, transverse sealing tension, and bottom material tension.

The unwinding tension is a process parameter that controls the tightness of the fabric of the bag-shaped film. It is often necessary to use a small tension to produce a roll film that can walk stably. When setting, adjust according to the tightness and flatness of the material

The longitudinal seal control portion is composed of a material from the radiation absorbing roller to the traction roller behind the longitudinal seal. Through two 45° angle steering plates, photoelectric correction detection head, front and rear adjustment roller sets and heat sealing, cooling knife. When the tension is too large, the aged material will walk more smoothly, but the friction between the material and the equipment will increase. Easy to scratch. It will also affect the stability of the tailor's cutting, punching, and rear position of the heat-sealed position.

After introducing the knowledge of many three-sided sealed bags, I believe you must have a better understanding of the three-sided sealed bag.
