The ultrasonic method is to use non-woven fabrics as materials, without any glue for pasting, and only need to install a roll of non-woven roller film to produce, saving process, wireless stitching, very beautiful and generous. What are the advantages of ultrasonic bag making?
1. The non-woven bag is ultrasonically welded, eliminating the need for needles and threads, and the trouble of frequent replacement of needles and threads. There is no broken joints or even broken needles of traditional sutures, and the non-woven fabrics can be trimmed and sealed neatly and locally. The stitches also play a decorative role. Strong adhesion, can achieve waterproof effect. The embossing is clear and the surface has a three-dimensional relief effect. The working speed is fast, the non-woven bag effect is better, and the quality is guaranteed.
2. The non-woven bag is processed by ultrasonic wave and special steel wheel, and the sealing edge will not crack, will not damage the cloth edge, and there will be no burr or curling phenomenon.
3. There is no need to preheat during manufacture, and it can run continuously.
4. The operation of the machine is simple, and it is not much different from the operation mode of the traditional sewing machine. It can be operated by ordinary sewing and cutting.
5. The production cost of non-woven bags is low, 5 to 6 times faster than traditional machines, and the efficiency is high.
