If you use an impulse heat sealer, you may not have even considered the importance of the congealing, or cooling step. Sealer Sales, one of the leading manufacturers of heat sealers, recently reminded us of the importance of congealing a seal. What exactly does this mean? Congeal means to cool under pressure.

If you are using a hand or foot sealer, then your model is officially classified as a manual sealer. This basically means that you should add the congeal step (also sometimes referred to as a dwell step) to your sealing process. This will make certain a secure and proper seal.

So, how do you do this? You can simply hold the sealing jaw down for a couple of seconds after the timer light has gone off to set the seal. This added step guarantees a proper seal. This will also help your sealer cool down before the next seal begins. The benefit to you with this added step is extended longevity of the heat-sealing elements.

With auto sealers, the manufacturer recommends the congeal (cooling) setting to be lengthened to at least two times greater than the heat setting time. This will give the seal ample opportunity to set and cool under pressure. It will also allow the heating element to properly cool down as well. Again, allowing the sealer to cool down this way will add longevity to all of the heat-sealing parts.

Be sure to contact ABC Office with any of your heat sealer questions. We also sell replacement parts for most heat sealer models.
