  What is ultrasonic package sealing?   Ultrasonic package sealing occurs when high frequency (ultrasonic) mechanical energy is transferred into two or more layers of thermoplastic materials. A strong, reliable molecular bond is formed between the layers. Nearly all packaging materials and laminates, with a thermoplastic sealing layer or coating, are suitable for the ultrasonic sealing (...

  Processing Techniques-Ultrasonic Packaging     Ultrasonic Bonding Ultrasonic bonding assembles two or more layers of materials by passing them between a vibrating horn and a rotary drum (often referred to as ananvil). The rotary drum is usually made from hardened steel and has a pattern of raised areas machined into it.  The high frequency mechanical motion of the vibrating h...

  Fabric & film processing is the bonding, slitting, or sealing of fabrics and films containing thermoplastic material(s). Typical thermoplastic materials found in fabrics and films include acrylics, nylon, polyester, polyethylene, polypropylene, polyvinylchloride, and urethane. Products from the textile, apparel, nonwovens, packaging, medical and automotive industries all benefit from th...

  Ultrasonic food processing involves a vibrating knife (guillotine) producing a nearly frictionless surface to which food products do not stick nor deform. The surface cleanly cuts or slits products including fillers such as nuts, raisins, dried fruit or chocolate morsels without displacement or ploughing. Ultrasonic cutting is used by many of the world’s largest and most prestigious food pr...

  What are the advantages of ultrasonic food processing?   1. Cleaner, repeatable and more consistent slits and cuts 2. Substantially reduced down time for clean up 3. Outstanding cut aesthetics for multi-layered and delicate products (cakes, sandwiches, baked goods, layered chees and pate products). 4. Wider cutting temperature range 5. Cuts cleanly through various densities and consist...
