What are the characteristics of nonwoven bag making machines?

Non-woven bag making machines are mainly used in the textile industry to produce various non-woven bags, including tote bags and packaging bags, in different shapes and styles. Non-woven bags made by these machines have a high degree of standardization and neat seams.

I. The Principle of Non-woven Bag Making Machines: The non-woven bag making machine uses a feeder to continuously deliver powder (colloid or liquid) into the hopper above the packaging machine. The feeding speed is controlled by photoelectric positioning equipment. Rolls of sealing paper (or other packaging materials) are guided by guide rollers to the collar forming device, where they are bent and then overlapped into a cylindrical shape by the longitudinal sealer. The material is automatically metered and filled into the bag. The transverse sealer, while heat-sealing and cutting, intermittently pulls the bag cylinder downwards, ultimately forming a flat bag with overlapping longitudinal seams and three-sided sealing, completing the sealing of one bag.

II. Features of Non-woven Bag Making Machines: 1. Utilizes ultrasonic welding, eliminating the need for needles and thread, saving the hassle of frequent needle and thread changes, and avoiding the broken thread joints of traditional sewing. It can also neatly cut and seal textiles in certain areas. The sewing process also serves a decorative purpose, with strong adhesion, waterproofing, clear embossing, and a more three-dimensional, embossed appearance. The high-speed operation and superior product quality ensure a premium look and quality. 2. Uses ultrasonic welding with specially designed steel wheels, ensuring the sealed edges do not crack or damage the fabric edges, and eliminating burrs and curling. 3. No preheating is required during production, and continuous operation is possible. 4. Simple operation, not much different from traditional sewing machines, generally operable by seamstresses. 5. Low cost, 5 to 6 times faster than traditional machines, and highly efficient.

Unlike traditional sewing, non-woven bag making machines offer faster production speeds and lower error rates. Non-woven bags made using non-woven bag making machines have neater seams. The cost of manual sewing is higher than that of nonwoven bag making machines. In summary, nonwoven bag making machines have significant advantages in both price and manufacturing process.
