Laboratory heat sealer
Device for the production of high quality heat seals and/or precise measurement of heat sealability of flexible packaging.
Download the leaflet Product description
Produces seals up to 300mm long x 5 to 25mm wide.
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 provides precision digital controls for this purpose.
Benefits
-
Choose heat sealing bar configuration, either single (upper) or dual (upper & lower, meets ASTM F2029)
-
User can easily change sealing bar for various surface areas or surface finishes
-
Accurate and repeatable seals due to precision ground sealing faces and jaw guidance system
-
Versatile applications for flexible materials, blister packs and pots
-
Low Maintenance – 12 months between calibrations
