Another advantage of ultrasonic sealing is that no adhesives or solvents are required, which means that certain types of recirculation can be performed and some cleaning steps can be eliminated. Ultrasonic technology is very environmentally friendly and consumes less energy due to the short welding or stamping process. Therefore, very thin packaging materials can be used, which has many economic and ecological benefits for the production of packaging.

Ultrasound can be used to weld different materials alone or in combination, for example, we are familiar with PP, PVC, PE, PET, composite materials or films, non-woven materials. The welding of these materials is long-term and high-quality, because ultrasonic waves Achieving visually beautiful and quality durable welding results. Because the tools in ultrasonic welding technology generate high temperatures instantly, it is very suitable for packaging heat-sensitive items. The advantage of "cold" welding is that it does not cause any damage to the packaging material when the machine is started and stopped.

1. Shell and top cover
The sealing of the top cover film and the welding of the sealing ring as well as the packaging sealing of the screening program are some of the more important applications solved by using ultrasonic welding machines. The welding mold can ensure its durability and protect the quality of the product by positioning the film without heating.
2. Film packaging
Residual product in the weld area can be safely separated by ultrasonic waves, thus ensuring an absolute seal, which significantly reduces the number of packaging leaks and enhances the durability of the product. Leon ultrasonic welding machine fully demonstrates this advantage in longitudinal continuous welding and transverse intermittent welding of hose bags, zipper bags and stand-up bags.

3. Packaging of PET materials
When PET materials in the packaging industry are welded using ultrasonics, they can quickly reach a high melting point and increase production. The sealing and separation functions of the blister can also be realized, and the functions of unsealing and authentic anti-counterfeiting can also be easily realized.

4. Beverage soft packaging
Soft drink packaging can be seen everywhere in daily life. The ultrasonic welding machine is especially suitable for coated cardboard packaging materials, which can ensure the sealing of the weld, and whether it has an aluminum film will not affect the welding. The sealing time is relatively short, the output is also high, and repeatable welding parameters can ensure the consistency of sealing quality.
