There are many non-woven bags made of ultrasonic heat-sealing technology on the market. Heat-sealing non-woven bags have advantages and disadvantages. Since the vast majority of heat-sealing non-woven bags are produced by a one-time forming machine, the production speed is many times faster than that of manual sewing, and a one-time forming machine exceeds the output of fifty people. According to the existing technology, the daily output of a production line reaches more than 50,000, which is incomparable by labor.

    When customers choose which process, it is best to determine the use of non-woven bags and the scope of advertising and promotion, and then decide which process to use, the best for them is the best.

    Although hot pressing has a great advantage in terms of output and cost, it still cannot replace sewing non-woven bags. One-time thermoforming technology is not up to the technology that can be produced on any bag. Some bags must be sewn manually, just like a three-dimensional edging bag that cannot be produced by a one-time molding machine. The one-time forming heat-sealing process can only produce flat non-woven bags. Although there is a process that can be used to make three-dimensional bags, it is not mature enough from a practical point of view and cannot be promoted. Another point is that sewn non-woven bags far surpass heat-sealing in terms of load-bearing and tensile performance. Normally heat-sealing non-woven bags are only suitable for light-bearing packaging bags.
