Heat sealers can generally be divided into two categories. The first is an impulse heat sealer with a jaw or clamp that is manually pressed to create the seal. With manual operation, the operator must place the bag or pouch between the jaws, wait a few seconds for the material to seal, and then allow it to cool. Impulse heat sealers can be available in both tabletop and handheld formats. Rotary band sealers operate slightly differently as they focus on the quality and consistency of the seal. A belt essentially 'feeds' the bag from one side to the other through the heating element of the machine. Thus, heat and pressure are applied to create the seal. When deciding, you should consider the material you are sealing and what the quality requirements are for your project. For example, if you need a sterile package, you should definitely consider a rotary heat sealer.
