Heat sealer

A heat sealer is a machine used to seal product packaging using heat. Continuous heat sealers (also known as Band type heat sealers) utilize heated moving belts. Impulse heat sealers use a stationary heated element. Good seals are a result of time, temperature and pressure for the correct clean material.

An Impulse sealer is a system, usually found on a "Bottom weld" machine. This type of machine uses two sealing elements, an upper and lower which fuse the material from both sides at the same time. The purpose of "Impulse sealing" is to improve the bounding of the two layers of film. This gives a faster and better seal for thicker or hard to seal material.
