Application of Ultrasonic Lace Machines in Non-woven Bag Production

Non-woven bags are made from non-woven fabric using a non-woven bag making machine, without the addition of any auxiliary materials or solvents. Therefore, they are a green product. They are also tough and durable, aesthetically pleasing, breathable, reusable, washable, and can be screen-printed with advertisements and logos. They are suitable for any company or industry for advertising and promotional purposes.

There are two types of equipment for making non-woven bags: fully automatic non-woven bag machines and ultrasonic lace machines (semi-automatic non-woven bag machines). Fully automatic non-woven bag machines have a high degree of automation and high efficiency, and are mainly used for the production of flat bags, gusseted bags, and bottom-gusseted bags. Therefore, they are widely used in large non-woven bag manufacturers with fixed orders.

Currently, most non-woven bag production is still carried out in small family-run workshops, processing non-woven bags according to customer requirements. In these factories, fully automatic non-woven bag machines are not very practical, and most use semi-automatic production equipment. The working principle of the ultrasonic lace machine is to use high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the workpiece, instantly causing friction between the molecules of the workpiece, reaching the melting point of the plastic, and thus completing the rapid melting of the solid material and completing the welding. The strength of the joint is close to that of a single piece of continuous material. As long as the joint surface of the product is designed to match, complete sealing is absolutely no problem.
