A multi-layered packaging film includes (a) an outer print layer, (b) an inner product-side layer, and (c) a lamination layer interposed between the outer print layer and the inner product-side layer.

Multi-layered packaging films

An ultrasonic welding system that includes an ultrasonic transducer configured to convert electricity to generate ultrasonic waves, wherein the waves propagate along a first direction from the transducer; and a sonotrode that includes a single-component body having nodal and anti-nodal regions, and configured to propagate ultrasonic waves received at a nodal region along a first direction; a plurality of redirecting features formed in the body and configured to cause received ultrasonic waves propagating along the first direction to propagate along a second direction, perpendicular to the first direction, upon encountering one or more of the redirecting features; wherein the body is further configured to stretch and compress along the second direction based on corresponding peaks and valleys of the waves propagating along the second direction; and at least one ultrasonic welding surface at an anti-nodal region of the body configured to oscillate based on the stretching and compressing, wherein opposing ends of the sonotrode comprise the nodal region, at least one of the opposing ends configured to receive the ultrasonic waves.

Transverse sonotrode design for ultrasonic welding

A method and apparatus for sealing films. In one embodiment the sealing device comprises a horn and an anvil. The film has a standard portion and an increased portion. Increased energy is applied to the film in the increased portion compared to the energy applied to the standard portion. Such a method allows for sealing of varying number of layers.
