SL-2 Digital Heat Sealer
  • Lako Tool is proud to introduce the SL-2 Digital Heat Sealer. The SL-2 Digital Heat Seal Tester is a precision heat sealer designed to duplicate heated crimp seals for the flexible packaging industry.

    The digitally controlled heat sealer allows independent upper and lower seal jaw temperature. The controlled temperature is assured to -± 1.1°C (± 2°F) across the entire width of the film sample. The dwell timer is switch controlled to insure actual dwell time on the seal specimen.

    The SL-2 Digital Heat Sealer insures sealing consistency for each sample and allows the operator to duplicate and analyze sealing applications in flexible packaging.

    • Digitally controlled temperature and dwell time
    • Independent upper and lower sealing temperatures
    • Measures actual dwell time on the sealing sample
    • One pair of Quick-Change Seal Jaw Inserts 5 to 12in long (12.7 to 30.4 cm) with desired seal pattern (The quick- change seal jaw inserts allow the operator to change the sealing pattern in a matter of minutes without having to change heaters or wiring)
    • Footswitch
    • Safety guards and switches for safe operation
    • Case with hardware


    • Additional quick-change seal jaw inserts with any seal pattern 5 to 12 in long (12.7 to 30.4 cm)
    • Manual sample loading tray accepts film 2 to 12 in wide (5 to 30.4 cm)
    • Phenolic seal jaw tray
  • Conforms to ASTM F2029 Standard Practices for Making Heatseals for Determination of Heatsealability of Flexible Webs as Measured by Seal Strength.
