These small yet powerful units are probably the most ubiquitous packaging machines, and are used to seal bags for a great variety of industries and applications. They are affordable and easy to use, which makes them a great alternative for light-duty bag sealing applications.

Impulse sealers fire a short burst of electricity through a specially designed heating wire to fuse the inner walls of bags. The length of the seal time will depend on the sealing characteristics of the bag being sealed.

The sealing process is simple: The operator places the bag over the sealing element and lowers the upper jaw thus activating the unit. The seal process quickly ends once the preset seal time is reached. The operator retrieves the sealed bag and repeats the process. Bags are sealed repeatedly and uniformly.
