Heat Seal Tester for Plastic Films Heat Seal & Hot Tack Tester

HST-H3 heat seal tester is based on the heat sealing method and is professionally applicable to the determination of heat seal temperature, dwell time, and the heat seal pressure of various composite films to guide industrial production. It is a necessary laboratory instrument for food enterprises, pharmaceutical enterprises, daily chemical products enterprises, packaging and raw material production enterprises.

Technical Features

  • Micro computer control, large LCD display, PVC operation panel and menu interface.

  • Self-innovated "constant temperature control" system improved the temperature accuracy.

  • Underneath type of gas cylinders ensure stable pressure during the test process.

  • The aluminum-encapsulated sealing jaws provide even and uniform temperature for different sealing surfaces

  • The upper and lower jaws could control the temperature independently, and the super long thermal cover design can meet the needs of different customers

  • Double start mode of manual and foot switch makes the test safe and convenient.

  • Embedded micro printer can print the test result quickly.

Test Principle

HST-H3 Heat Seal Tester is composed of upper and lower heat sealing jaws. Before the test, preset the heat seal temperature, pressure and dwell time value, place the specimen in between the upper and lower jaws, and then press start button. The whole sealing process can be finished automatically.

Test Standard

The instrument conforms to many national and international standards:QB/T 2358、ASTM F2029、YBB 00122003
