And there are two most common manufacturing processes for non-woven bags, that is, sewing and ultrasonic bonding. Also the laminated non woven bags have these 2 ways to make.
The main difference between them is that the sewing is manual sewing, while the ultrasonic bonding is machine heat pressing. So, how should you choose these two processes when customizing non-woven bags? Should it be sewn or ironed?
In fact, sewing and ironing have their own advantages and disadvantages. The sewn bags are relatively firm after stitching, but the shipment is slow. The characteristics of this type of non-woven bag are that the cost is lower than that of the sewn non-woven bag, and the delivery speed is fast.
Some ultrasonic hot-pressed non-woven bags can be produced automatically by a non-woven bag making machine, and only one or two labors are needed to produce tens of thousands of non-woven bags a day, although there are also some non-woven bags that require manual hot pressing bags, but its production speed is far greater than the sewing output.
The disadvantage of the hot-pressed non-woven bag is that the tensile strength is not very good. The principle is to heat the two layers of cloth together at high temperature, so the firmness is not very strong and cannot bear a large weight. However, the ultrasonic hot-pressed non-woven bag has various patterns of pattern molds, and you can choose the lace pattern you like.
Choosing a non-woven environmental protection bag needs to be considered from your needs. It is recommended that you choose a manual sewn non-woven bag if you consider the quality. If you are looking for a good-looking and cheap price, then choosing an ultrasonic non-woven bag is also a good choice.
