Heat seal test is to determine the suitable sealing parameters (sealing temperature, dwell time and pressure) for materials. ASTM F2029 is the standard practice for making heat seals for the determination of the heat sealability 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.
HST-H6 Heat Seal Tester 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.
PSST-100 Heat Seal Strength Tester is a professional heat seal strength tester for plastic films, composite films and other materials. This instrument is suitable for on-site quantitative inspection.
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.
