For packaging with thermoplastic sealing layers, such as capsules, pouches, drink cartons, cups and trays, ultrasonic sealing provides a large number of options: above all, high cycle rates and tight seals despite potential product residues in the seal area.

Ultrasonic technology fulfills all criteria of process optimization and validation crucial to food packaging companies.





Application groups




Capsules, tea bags

Sealing of lid films, welding of seal rings and embedding

offilters are the most important applications for which

ultrasonicwelding provides a solution. The weld tools

hold the film inplace by means of vacuum. Shelf life

and product protection

are ensured due to the tools being cold.



Spouts, valves, zippers

With ultrasonics, fast and safe welding of injectionmolded

degassing valves or spouts on films of anytype is possible.

Film shrinkage is prevented andthe barrier properties are

not jeopardized sinceultrasonics only excites the molecules

in the actualsealing layer. Moreover, ultrasonics allows for

safeintegration of zippers for re-sealable pouches

andwelding of the zipper ends (zipper-crushing)





Film packaging

With ultrasonics it is possible to safely push productresidues
out of the seal area, which ensures absolutelytight sealing.
This significantly reduces the number ofleaking packaging
and shelf life of the products in thesupermarkets is increased.
Ultrasonics provides thisadvantage for stand-up pouches,
chained bags andbags, both at longitudinal and transverse
joints,in intermittent and continuous applica






Drink packaging

Ultrasonic welding is very well suited for coated cartonpackaging

 material. Despite wetting with filled products,tight seals are ensured

with or without aluminum barrier.Integration of spouts is easily

possible. High output dueto short sealing times. Repeatable

parameters ensure consistentlyhigh sealing quality.
