Talk to an expertProduct Introduction
The sealing quality of plastic packaging film is one of the strongest indicators of overall product quality — it has a direct bearing on how well goods are protected, how long they stay fresh, and whether the packaging is safe for consumers. The TS-HS1A Heat Seal Tester was designed to help manufacturers pin down the ideal sealing temperature, sealing speed, and sealing pressure for a broad range of materials, from plastic films and flexible laminated packaging to coated paper, aluminum foil, and other heat-sealable composites.
Built for consistent, dependable results, this instrument has become a go-to tool in research labs, classrooms, and production facilities alike. It is used by film converters, food and pharmaceutical companies, independent testing labs, and schools that need trustworthy, repeatable heat-seal data to support product development and regulatory compliance.

Applications
Flexible Packaging Film Converters
Flexible-packaging flora and film converters evaluate seal strength, seal integrity, and feasibility of processing home windows even as developing new products.
Food & Beverage Manufacturers
Food and beverage manufacturers check whether their packaging is sufficiently sealed to protect against contamination, leakage and spoilage.
Pharmaceutical & Medical Device Packaging
Pharmaceutical and medical-device packaging manufacturers verifying that seals adhere to strict sterility and regulatory requirements.
