Impulse sealer
There are four sealing methods depending on your purpose and usage. Sealers
refer to machines in general that seal the opening or loose ends of plastic-

called heat sealers.
Heat-sealing technologies for general use include the following:
1
Impulse sealer,
2
Constant heat sealer
3
Ultrasonic sealer,
4
High-frequency sealer
Van der Stahl Scientific's
products are mainly the impulse sealer in the above
categories. An impulse sealer heat-seals objects by sending high current on
impulse to a heater ribbon, equipped on the surface of the heat-sealing blade,
to generate heat that enables thermal-sealing through thermal conductivity.
The section to be sealed is placed between the heat-sealing blades, pressed,
and thermal-fused when current and heat are delivered on impulse* through
the heater ribbon. After the current stops, a cooling process is necessary
during which the pressure is maintained.
*
The name “impulse sealer” is derived from the fact that the current and heat
are delivered on impulse, or instantaneously.
