Apart from traditional sewing method for making recycle bag, the alternative method is ultrasonic thermal bonding. This type of recycle bag mostly made from 75g non-woven fabric & it is sealed by the thermal heat generated from the ultrasonic machine, so it is also known as thermal bonding recycle bag. As there is no sewing thread for the bag, so there should be no broken thread and it saves time for mass production. You can find ultrasonic recycle bag can provide you a more competitive price.
