Heat seal test is to determine the suitable sealing parameters (sealing temperature, dwell time and pressure) for materials.
Complies with ASTM F2029 - Standard Practices for Making Heatseals for Determination of Heatsealability of Flexible Webs as Measured by Seal Strength
C630H Heat Seal Tester can be used to determine the optimal heat sealing parameters including dwell time, sealing pressure and sealing temperature for plastic films, flexible composite films, plastic coated paper and other heat-sealable films.
HST-H3 Heat Seal Tester (Laboratory Heat Sealer) can be used to seal specimen for further determination of seal parameters of basic films, laminated films, coating paper and other heat sealing laminated films according to the requirement of related standards.
CLASSIC 513 Gradient Heat Seal Tester is professionally designed for the determination of heatsealability of plastic films, composite films, coated paper, and other sealing films under certain sealing speed, pressure and 5 different temperatures.
i-Thermotek 2400 Heat Seal & Hot Tack Tester can be used for seal strength test after the seal immediately (hot tack) or waiting it cools to room temperature (heat seal). It can be used for plastic films, composite films and other packaging materials.
