Test Principle
The heat seal tester consists of upper and lower heat-sealing jaws. Before the test, preset the values for heat-sealing temperature, pressure, and dwell time. Then, place the specimen between the upper and lower jaws and press the start button. The entire sealing process is completed 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
The instrument can seal various materials, including plastic film, plastic composite film, paper-plastic composite film, co-extruded film, aluminum film, aluminum foil, and aluminum-foil composite film. The heat-sealing surfaces can be designed according to users' requirements, with smooth surfaces and customizable widths.
|
Films with Decorative Pattern Surface
The instrument can seal various materials, including plastic film, plastic composite film, paper-plastic composite film, co-extruded film, aluminum film, aluminum foil, and aluminum-foil composite film. The heat-sealing surfaces can be designed according to users' requirements, with decorative pattern surfaces and customizable widths.
|
Extended Applications |
Covers of Jelly Cups
The device consists of an upper and a lower jaw. The upper jaw is round, while the lower jaw is designed as a sample mold, precisely fitting the size of the jelly cup. To complete the heat seal, the jelly cup is placed in the lower jaw mold, and the upper jaw is pressed down (customization required).
|
Plastic Flexible Tubes
For flexible plastic tubes, the bottom of the tube is placed between the upper and lower jaws, which are then sealed to form a package.
