A modular stand-alone ultrasonic bag sealing system has an ultrasonic sealer assembly that utilizes a sonotrode and an anvil that are actuated together to form a bag seal in a bag configured therebetween. The system also has an integral control system that is physically configured on the housing of the system and runs a control software. The control software is configured to control the ultrasonic sealer assembly to close and open to seal bags. The controller may have a plurality of signal inputs for receiving input signals from a bag feeder assembly or from an auxiliary machine. The system may also have an integral bag feeder assembly that has an index roller for feeding a bag to the ultrasonic sealer assembly. The system is configured for quick integration into a process line and has versatility of communication through the control software and signal inputs and outputs.

A punch assembly is provided in a form, fill, and seal machine that provides a package that includes a sealed end portion and contains an article. The punch assembly includes a housing, and a heat sink provided in and retained by the housing, where the heat sink includes a punch tip that is to provide an opening in the sealed end portion of the package. The punch assembly also includes a coil heater contacting the heat sink to provide heat to the heat sink and the punch tip, where one or more air gaps are provided between the housing and the heat sink to prevent heat transfer from the heat sink to a seal jaw assembly of the form, fill, and seal machine.

Crimped seals that are formed in overlapping portions of a packaging material are tested for quality. Initially, the packaging material is installed on first and second clamps. A portion of the packaging material is then extended between first and second crimpers. The first and second crimpers are moved into engagement with the portion of the packaging material to form a crimped seal. During this engagement, the amount of force that is exerted on the portion of the packaging material by the first and second crimpers to form the crimped seal is measured. Then, the first and second clamps are moved to pull apart the crimped seal. The amount of force that is exerted by the first and second clamps to pull apart the crimped seal is also measured. An apparatus for testing the quality of such crimped seals is also provided.
