HST-H3 Heat Seal Tester is professionally applicable to the determination of heat-sealing temperature, dwelling time, and heat-sealing pressure.
Product Features
-
7-inch touch interface is more convenient to operate.
-
Self-innovated "constant temperature control" system improves the accuracy.
-
The synchronous circuit of bottom gas cylinder ensures the balance of pressure.
-
Aluminum-sealing jaws provide even and uniform temperature for sealing surfaces.
-
The upper and lower jaws controlling the temperature independently and the super-long thermal cover can meet different needs.
-
The design of anti-scald and leakage protection is more secure to test.
-
Dual switch modes: manual and pedal.
-
Micro-printer.
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.
Test Standards
This test instrument conforms to many national and international standards:
ASTM F2029, QB/T 2358, YBB 00122003
Applications
Basic Applications |
Films with Smooth Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface should be smooth and width can be designed based on users requirements.
|
Films with Decorative Pattern Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface can be designed based on users requirements.
|
Extended Applications |
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.
