HSE-3 Laboratory Heat Sealer

For production of high-quality heat seals and/or precise measurement of heat sealability of flexible packaging. Produces seals up to 300mm long x 5 to 25mm wide.

The HSE-3 Laboratory Heat Sealer is used for both R&D and quality control as well as for sealing of small amounts of packages in production. Different to the smaller laboratory heat sealer HS-2 this type is equipped with longer sealing jaws of up to 350 mm and provides optionally a blister pack attachment. The sealing head can be splitted from control unit to allow sealing of filled bags.

Precise control of heat sealing process variables (temperature, pressure, and time), enables an optimal balance of material specification, packaging machine speed and seal integrity. Accuracy and repeatability in laboratory heat seal testing is vital, and the HSE-3 Laboratory Heat Sealer provides precision digital controls for this purpose.
