Ultrasonic sealing offers a wide range of options for the use of thermoplastic coated packaging materials such as capsules, bags, beverage cartons, beverage cups, and housings. High-speed production and close welding are ensured even with fillers remaining in the welding area. With ultrasonic technology, it is easy to realieze optimation and validation of food packaging process.
Capsules & tea bags
The sealing of the top cover film, rings and the encapsulation of the filter material are important applications in which ultrasonic welding used. The molds that do not require heating but still ensure durability and protection of the product.
Spouts, valves & zippers
Ultrasonic welding can quickly and safely seal the degas valves or screw caps (nozzle) and all kinds of film. Because ultrasonic energy only makes vibration of the molecules of sealing layer, so that film shrinkage can be avoided without affecting the barrier properties.
With ultrasonics it is possible to safely push product residues out of the seal area, which ensures absolutely tight sealing.This significantly reduces the number of leaking packaging and shelf life of the products in the supermarkets is increased.
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.
Cups, blister packs, trays
On PET applications in particular, ultrasonics quickly reaches the high melting point and therefore results in an increase in production output. Sealing and separating blister packs is easily possible
