Laboratory Package Heat Seal Tester

Heat Seal Tester is professionally applicable to the determination of heat- sealing temperature, dwelling time and the heat-sealing pressure which are references to the production of aseptic bag, food, pharmaceutical, daily chemicals, package and raw material.

Features

Micro-computer control tests. Touch interface is easier to operate.

Self-innovated "constant temperature control" system improves the accuracy of temperature.

The synchronous circuit of single bottom cylinder ensures the balance of pressure.

Aluminum-sealing jaws provide even and uniform temperature for different sealing surfaces 

The upper and lower jaws controlling the temperature independently and the super-long thermal cover can meet different needs.

Dual switch modes of manual and foot make the safety and convenience.

Micro-printer embedded can get the results quickly.

The design of anti-scald and leakage protection is more secure to test.

Principle

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

Standards

QB/T 2358, ASTM F2029, YBB 00122003.

Applications

Films with Smooth Surface                  

Films with Decorative Pattern Surface

Covers of Jelly Cups                 The instrument is composed of the upper and lower jaws. The upper one is round-shape while the lower one is designed as a specimen mould whose size exactly fits the jelly cup. Put the jelly cup in the mould of lower jaw, and heat seal can be finished by upper jaw pushing (Customization required).

Plastic Flexible Tubes                 The bottom of plastic flexible tubes are placed in between upper and lower jaws and then sealed to form a package.
