A heat sealer is a machine used to seal products, packaging, and other thermoplastic materials using heat.
Types of heat sealers
- Continuous heat sealers- (also known as Band type heat sealers) utilize heated moving belts.
- Impulse heat sealers- use a stationary element which is heated with each sealing cycle .An impulse sealer is a system often 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 bonding of the two layers of film. This gives a faster and better seal for thicker or hard to seal material.
- Hot bar sealers- use one (or two) heated bars which contact the material to form a bond.
- Induction sealing is a non-contact type of sealing used for inner seals in bottle caps.
- Ultrasonic welding uses high-frequency ultrasonic acoustic vibrations to workpieces being held together under pressure to create a weld.
A type of heat sealer is also used to piece together plastic side panels for light-weight agricultural buildings such as greenhouses and sheds. This version is guided along the floor by four wheels.
Good seals are a result of time, temperature and pressure for the correct clean material.
