For rapid determination of heat sealability of flexible packaging. Produces 3 or 5 independently temperature controlled seals, up to 15mm wide x 30mm long.
HSG-3 & 5 Gradient Heat Sealers
Precise control of heat sealing process variables (temperature, pressure, and dwell 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 HSG-1 Gradient provides precision digital controls for this purpose. Fitted with either 3 or 5 sets of sealing bars with individual temperature controls to create a temperature gradient across the film.
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
Precise pressure calibration of standard surface area jaw face
Temperature, pressure and dwell time digital controllers
Jaws constructed in aluminum and silicon with precision ground faces
Range of jaw face surfaces including Matched Crimp and Teflon Coating
Auto cycle feature for greater user convenience with multiple samples
