A heat sealer (sometimes referred to as a bag sealer machine) has a heating element that heats up and melts a thin layer of plastic on both sides of a seam, creating a strong bond.
The heating element in an impulse heat sealer is not heated up continuously. Instead, heat is generated when the device is switched on and the sealing arm is engaged – completing the electrical circuit.
When materials are placed on the sealing area, the operator simply uses the handle to clamp the sealing arms (jaws) and apply pressure to form the seal.
The electric current heats the element for a specific time, which can be adjusted and controlled using the seal timer dial and LED sealing indicator.
If heat is not applied long enough, the seal will be incomplete and weak, but too much heat will produce smoke and cause the plastic to burn.
Depending on which heat sealer you choose, it may have an integrated safety cutter knife that allows you to remove any excess material before lifting the bag off the sealing area. For more information about our heat sealers
