The PACKAGING division offers fast and airtight ultrasonic packaging sealing solutions with a focus on high throughput and sustainability. Different materials and new packaging designs require continuous development of new economic solutions for the packaging industry. We develop and deliver the complete solution for the packaging machine and incorporate ultrasonic sealing – fast – safe – airtight. In addition, we offer solutions for food cutting by the use of ultrasonic knives.

Packaging for coffee

Capsules, tea bags

Sealing of lid films, welding of seal rings and embedding of filters are the most important applications for which ultrasonic welding provides a solution. The weld tools hold the film in place by means of vacuum. Shelf life and product protection are ensured due to the tools being cold.

Sealing of lid films, welding of seal rings, embedding of filters

Spouts, valves, zippers

With ultrasonics, fast and safe welding of injection molded degassing valves or spouts on films of any type is possible. Film shrinkage is prevented and the barrier properties are not jeopardized since ultrasonics only excites the molecules in the actual sealing layer. Moreover, ultrasonics allows for safe integration of zippers for re-sealable pouches and welding of the zipper ends (zipper-crushing).

Drink packaging

Ultrasonic welding is very well suited for coated carton packaging material. Despite wetting with filled products, tight seals are ensured with or without aluminum barrier. Integration of spouts is easily possible. High output due to short sealing times. Repeatable parameters ensure consistently high sealing quality.
