We often get this question: What is the difference between impulse sealing and direct heat sealing and how do I choose??
Impulse sealers – require no warm up time and seal by applying a pulse of energy to the sealing area, followed immediately by cooling. Impulse sealers only use power when the jaw is lowered. **So if you are just sealing your every day poly bags, an impulse sealer will do the trick.**
Direct heat sealers (constant heat) – maintain constant heat in both jaws. Direct heat sealers use power as long as the machine is turned on. As a result, direct heat sealers possess better heat penetration in order to seal thicker materials. **If you are sealing thicker materials such as kraft paper or anything with gussets, go with a direct heat sealer.**
