At present, the most environmentally friendly bags are non-woven bags, and the most used ones are ultrasonic non-woven welding machines.
Working principle: the high frequency oscillation is used to transmit the sound wave from the welding head to the welding surface of the workpiece, and the workpiece molecules are frictionally generated to reach the melting point of the plastic, thereby completing the rapid dissolution of the solid material and completing the welding. The strength of the joint is close to a whole piece of continuous material. As long as the joint surface of the product is designed to match, there is absolutely no problem in completely sealing.
Compared with the traditional pin-type wire stitching, it has the following advantages:
1, the use of ultrasonic welding, the use of needle thread, eliminating the need for frequent needle change, without the traditional line stitching of the broken joints, but also the textile can be neatly cut and sealed. The stitching also plays the role of decoration, strong adhesion, waterproof effect, clear embossing, more three-dimensional relief effect on the surface, fast working speed, good product effect and high-grade appearance; quality is guaranteed.
2, using ultrasonic and special steel wheel processing, the edge of the seal does not crack, does not hurt the edge of the cloth, and there is no flashing, curling phenomenon.
3, no preheating during manufacturing, and continuous operation.
4, easy to operate, and the traditional sewing machine operation method is not much different, ordinary sewing workers can operate
5, low cost, 5 to 6 times faster than traditional machines, high efficiency
