Non woven bag is one of the most economical, convenient and environmentally friendly bags, which compared with the canvas bag, oxford bag.

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.

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 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.
