The TS-HS5A Heat Seal Tester is a precision laboratory instrument engineered to evaluate the temperature, pressure, and dwell time required to produce a reliable heat seal on flexible films and packaging laminates. By reproducing real-world sealing conditions under tightly controlled parameters, the instrument allows manufacturers and testing laboratories to determine the optimal sealing window for a given material before it moves into full-scale production.
Because seal integrity has a direct bearing on shelf life, tamper evidence, and product safety, the TS-HS5A has become a standard piece of equipment across a wide range of industries. It is routinely used by quality inspection organizations, drug control and regulatory institutions, packaging and film converters, food processing companies, pharmaceutical manufacturers, and producers in the personal care sector to confirm that packaging materials meet the sealing performance demanded by their end use.
Key Features
- Five-point heat sealing capability, allowing up to six independent temperature settings to be configured simultaneously across the lower bar and five upper bars — ideal for multi-zone seal profiling.
- Independent temperature control and setting for both the upper and lower heat seal bars, enabling asymmetric sealing trials that mirror real production conditions.
- Digital P.I.D. temperature control delivers tighter, more consistent temperature regulation than conventional controllers, and the temperature sensor is designed for straightforward calibration.
