UVA’s ULTRASONIC SEALING SYSTEM FOR LIQUIDS

UVA Packaging has introduced an ultrasonic sealing system
on its Vertical Form, Fill and Sealing machinery for liquid packing .

Benefits of ultrasonic sealing are:

  • Tight seals even by sealing through the liquid
  • Film savings because of smaller 'bag head' 
  • Short seal times even for laminate products
  • Seal quality check for each indivdual bag
  • Low maintenance cost

Ultrasonic sealing is a method for joining thermoplastic material together
by emitting acoustic vibrations, creating a tight, strong seal.
The film is sealed with heat from friction generated by an oscillating tool,
eliminating the need for direct heat contact. Typical heat sealing systems
often require intensive cleaning as the product tends to melt and accumulate
in the sealing zone. The ultrasonic process can seal film structures
that have been contaminated by product, minimising stoppages.

UVA Packaging experienced this technology to be extremely suitable for bagged liquids, 
confectionaries, salads and snacks, however each of the application requires an own approach.
