Cups, bowls, trays and blisters

The opening behaviour of packagings plays an increasingly important role in the customer’s product acceptance. This is also for consumer goods. Especially elder people have great demands to packagings and are the central clientele for them.

SONIQTWIST® is the new ultrasonic sealing technology for containers and tins. The technique we have developed and patented is based on an entirely new way of using ultrasonics to seal and bond cup-lid combinations. The technology has proved itself exceptionally well, especially in peelable packaging systems. Exceptional process advantages include the low partial stresses and consistant peeling, even on contaminated areas of the seal. SONIQTWIST® is equally suited for use with either lids or lidding films.

Ultrasonic Welding Sytem TSP8000

The torsional Ultrasonic Welding System TSP8000 consists of an
extremely high-rigid pneumatic press, a torsional ultrasonic
head, an ultrasonic generator and a microprocessor unit for
control of the welding process. The welding quality can be
monitored continuously during production through preselection
of corresponding tolerance windows for the different
parameters like welding time, welding energy, welding power,
welding force and welding distance.

Advantages

• Realization of firm or peelable connections in fractions of a second
• If product residues from the filling process remain in the sealing zone, they are completely displaced from the joint area by the ultrasonic vibration
• Monitoring of the welding parameters significantly contributes to a consistent seal quality

Application range

• Thermoformed cups with lid
  (meat, milk and cheese products, convenience food, salads etc.) 
• Injection-mould containers
  (Ice cream, milk and cheese products, spreads, pet food etc.)
• Containers made of aluminium with lid
  (pet food, spreads, fish products, pastry etc.)
