The most environment-friendly bags are non-woven bags, while many non-woven bags on the market are made with needle-thread stitching process. Due to the low production threshold of sewing machines, many people can process non-woven bags, resulting in different quality of bags. Now we use the high frequency oscillation of ultrasonic junction technique, the welding head are transmitted by sound waves non-woven welding face, instantly making non-woven friction, achieve plastic melting point, thus finish quickly dissolved solid material, to complete the welding. The joint strength is close to that of a whole piece of continuous fabric, and there is absolutely no problem with complete sealing.
Compared with traditional sewed non woven bag , it has the following advantages:
1, the use of ultrasonic bag without sew, save the trouble of frequent needle and thread change, there is no traditional thread broken joint situation, but also on the textiles for neat local shear and seal. Suture also plays the role of decoration, strong bonding force, can achieve waterproof effect, embossing clear, the surface is more three-dimensional relief effect, work fast, the product effect is better and more high-grade beautiful; Quality is guaranteed.
2, the use of ultrasonic and special steel wheel processing, sealing edge no cracking, no damage to the bag edge, and no burr, curling phenomenon.
3, simple operation, low cost, high efficiency. It is faster than the traditional machine from 5 to 6 times,.
