ULTRASONIC SEALING OF FOOD PRODUCT PACKAGING

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. This technology is used for sealing plastics as well as laminating nonwoven materials found in certain types of food packaging.

Ultrasonic sealing of food packaging fulfills all criteria of process optimization and validation crucial to companies in this sector. Herrmann Ultrasonics is ready to provide you with full expertise to implement and integrate this equipment into your operations. Click here to get in touch with us today.

Arrow

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 in heat sealing machines for food packaging hold the film in place by means of vacuum. Shelf life and product protection are ensured due to the tools being cold.

Spouts, valves, zippers

With ultrasonic packaging equipment, 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, ultrasonic plastic packaging sealers allow for safe integration of zippers for re-sealable pouches and welding of the zipper ends (zipper-crushing).

Film packaging

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 plastic bag welders provide this advantage for stand-up pouches, chained bags and bags, both at longitudinal and transverse joints, in intermittent and continuous applications.

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.

Cups, blister packs, trays

On PET applications in particular, ultrasonic sealing packaging machines quickly reach the high melting point and therefore result in an increase in production output. Sealing and separating blister packs is easily possible, also integration of tear out sections and tamper-evident seals.
