Charles H. Trillich is the President of Packworld USA and for the past 25 years has dedicated himself to developing “state of the art”, impulse heat-sealing solutions for the Medical/Pharmaceutical/Healthcare industry. Under his leadership, Packworld has become the leader in resistance controlled impulse heat-sealing solutions and specializes in engineering precision controlled, validatable heat sealing machinery used throughout the industry. Packworld’s entire line of validatable pouch sealing machines come equipped with the advanced TOSS Technology, eliminating the inherent errors and lag in response time found in machines controlled with thermocouples. The TOSS controls and components are used to create precision systems that produce perfect seals - every time.

Heat Sealing Q&A
-
Asked March 9th, 2009
The ability of a sealer to be universal in it its ability to seal different materials depends upon the range of the time, temperature, and pressure adjustments that are available on the machine. In addition, consistently repeatable seals can only be made if the machine has precise temperature controls that automatically adjust to the gradual heat build up in the machine during the course of the day. For seals to be uniform over their full length, it is imperative that the heat and pressure distribution be uniform over the full length of the seal bar.
Tyvek/PE pouches are best sealed by applying heat from only the PE side. The sealing of foil laminates requires additional heat energy during the sealing process because the foil layer is an excellent thermal conductor that will conduct heat away form the seal area very readily. In this case the sealing is best achieved by providing heat from both sides. The additional heat delivered will accelerate the sealing process and compensate for the heat absorbed by the foil. Some impulse sealing machines are designed to provide the option of heating from either one or both sides.
