The TS-HS1 Heat Seal Tester is a precision instrument engineered to accurately measure the heat seal temperature range, seal strength, optimum sealing speed, and sealing pressure of plastic film, flexible packaging composite film, coated paper, aluminum foil, and other packaging substrates. Built for reliability and repeatability, it has become an essential quality control tool across the plastic film, food, and pharmaceutical manufacturing sectors, and is equally valued by testing institutions and academic laboratories for scientific research and teaching applications.
Key Features
- Independent temperature control for the upper and lower heat seal jaws, allowing each to be set separately for precise process tuning.
- Pneumatically driven using compressed air for consistent, repeatable sealing pressure.
- Dual operating modes — automatic and manual — with a foot switch provided for convenient manual operation.
