Ultrasonic Sealing Laser Film Laminated Non Woven Bags

Ultrasonic sealing laser film laminated non woven bags utilize high-frequency acoustic waves to fuse the fibers, offering significant advantages over traditional needle-stitching or heat-sealing methods: Traditional stitching can pierce the non-woven fabric fibers, creating micro-tear points; in contrast, ultrasonic welding achieves molecular-level fusion without the use of needles or threads, thereby eliminating the risk of thread slippage or tearing caused by needle holes. Ultrasonic vibration welding can complete a single weld point or edge sealing in just a fraction of a second, making it highly suitable for automated high-speed mass production (with daily output capacity reaching tens of thousands of units). No wires, adhesives, or chemical binders are required, and complex sewing processes are eliminated, significantly reducing long-term material and labor costs.By eliminating the use of organic solvents or adhesives, it prevents the release of hazardous chemical gases during production and use.Ultrasonic energy is concentrated solely on the joint area during the brief welding press phase, eliminating the need for prolonged continuous heating; consequently, overall energy consumption is significantly lower than that of conventional thermal sealing processes.

The printing method of Ultrasonic sealing laser film laminated non woven bags are gravure printing, one color needs a printing plate. We usually 4 CMYK plates and 1~2 spot colors plates to printing the complicated colors. The cylinder printing can full-set printing the spot color, it is equal to dye a Pantone color fabric, so you can obtain bags with the color you want but without dying a fabric because of the MOQ limitation.

We can produce bags according to customer requirements on design, materials and specifications, Don't be hesitate to contact us any time and give us the bag specifications if you need the bags, we will quote you a nice price.
