Product Introduction

The TSB-A Heat Seal Tester is a high-precision laboratory instrument engineered to evaluate the heat sealing performance of flexible packaging materials under controlled conditions. It accurately determines the optimal heat seal temperature, sealing pressure, dwell time, and seal strength required to produce reliable, consistent, and durable seals. By simulating real production sealing conditions, the instrument enables manufacturers to optimize packaging processes, reduce material waste, and ensure superior product protection throughout storage and transportation.

Designed for versatility, the TSB-A Heat Seal Tester is compatible with a wide range of heat-sealable materials, including plastic films, multilayer flexible packaging laminates, coated paper, aluminum foil, and composite packaging materials. Its precise temperature control and uniform pressure distribution allow users to identify the ideal sealing parameters for different material combinations, ensuring repeatable and accurate test results. The instrument is an essential tool for material development, process validation, and routine quality inspection.

Key Features

  • Independent Upper & Lower Jaw Temperature Control enables separate temperature settings for each sealing jaw, ensuring precise and consistent heat sealing across different material combinations.
  • Pneumatic Sealing System delivers stable, uniform sealing pressure using compressed air for highly repeatable and accurate test results.
  • Automatic & Manual Operating Modes support programmable automatic testing or convenient foot-switch operation for flexible laboratory workflows.
  • Simple Temperature Calibration allows quick and accurate calibration to maintain reliable temperature control and long-term testing accuracy.
