Industry applications



Food


Ultrasonic sealing provides production possibilities for packaging materials using thermoplastic coatings, such as capsules, bags, beverage cartons, beverage cups and covers, etc .: Even if fillers remain in the weld area, high-speed production is still ensured and manufactured Out a tight weld.

With the help of ultrasonic technology, process optimization and product verification in food packaging can be easily achieved.





Application category








Shell, tea bag

The sealing of the top cover film, the welding of the seal ring and the sealing of the filter packaging are the most important applications that are solved using ultrasound.

The welding mold positions the film by vacuum. A mold that does not require heating guarantees its durability and protects the product.


Nozzle, valve, zipper

Ultrasonics can quickly and safely weld degassing valves or screw caps (spouts) and all kinds of films.

Because ultrasound only vibrates the molecules of the sealing layer,

This prevents film shrinkage and does not affect barrier properties.

In addition, the zipper can be safely integrated into a re-openable bag by ultrasonic waves, and the zipper end is pressed (zipper pressed).


Film packaging

Ultrasonic energy safely separates residual products in the weld zone,

This guarantees an absolute seal. This can significantly reduce the number of packaging leaks and enhance product durability.

This advantage is fully demonstrated in the longitudinal continuous welding and horizontal intermittent welding of zipper bags and hose bags.




Beverage packaging

Ultrasonic welding is particularly suitable for coated cardboard packaging materials.

Although the product is wet, it can still ensure the tightness of the weld.

It does not matter whether it has an aluminum film or not. The nozzle can be integrated normally.

Short sealing time and high yield. Repeatable welding parameters ensure consistent seal quality.







Cover, blister, tray

Especially in PET applications, ultrasound can quickly reach high melting points and increase yield.

The blister can be sealed and separated, and the unsealing and genuine anti-counterfeiting functions can also be easily realized.
