Polythene/Impulse Heat Sealers Sri Lanka designed for the continuous sealing of thermoplastic films such as polyethylene. These sealers operate on the impulse sealing method, controlled by a plug-in transistorized circuit board. They work by delivering an instantaneous high current impulse to a heater ribbon on the device surface.
These small yet powerful units are probably the most ubiquitous packaging machines, and used for??sealing 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.
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 sealed uniformly.
