When selecting a sealer, it is important to have a sense of the material which will be sealed. Try and have the material thickness and width available as this will make your selection process much easier. This will ensure the sealer you purchase is capable of sealing your material.

What is the difference between an impulse and direct heat sealer?

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.**
