System and method of implementing ultrasonic sealing in packages

Abstract

The present invention is an ultrasonic sealing method for sealing together multiple layers, of materials of different composite and may be dissimilar in nature the method comprising the steps of, a) feeding at least two work-pieces between an ultrasonic horn and an anvil, wherein said at least two work-pieces comprise a shipping envelope mailer with or without a cushion layer as a variable layered material b) sealing said two work-pieces, wherein said sealing comprises, (i) the outer layers may or may not be pre coated with a polymer and (ii) generating vibratory energy by a transducer and applying it to the horn which causes the horn to vibrate, wherein the frictional forces caused between the vibrating horn, and the anvil produces heat which is used to seal the two work-pieces together.
