Heat Seal Tester - QT-HST-E

ASTM F 2029

Qualitest QT-HST-E is heat seal testing equipment specially designed to simulate heat sealing condition and affecting parameters for determination of heat sealing ability of plastic films, composite films, coated paper, and other sealing films under specified sealing conditions.

The heat sealing ability of materials is a function of temperature, pressure and duration of temperature and pressure applied for creating a seal and greatly affected by the factors of melting point, thermal stability, fluidity and thickness. The optimal heat seal ability parameters can be obtained accurately and efficiently.

Applications

It is widely used in food industries, pharmaceutical industries and packaging industries to test their packaging material and define packaging procedure for packaging operation and quality control of product packaging and products.

It can test wide range of materials including plastic films, plastic composite films, paper-plastic composite films, aluminized films, aluminum foil, aluminum composite films, high barrier films, rigid films, stretch films, and many other materials like PET, OPP, CPP, LDPE, BOPP, etc.

It can also be used to evaluate heat sealing properties of engineering plastics, rubber, water proofing materials, and thermal insulation materials like. PP, PVC, PVDC, and nylon Packages: plastics, rubber, paper, paper-plastic composite etc.

Features

• Electronic control of sealing variants (Temperature and Pressure) and its measurement with respect to time;
• Precise control of Temperature, pressure and sealing time;
• Independent heating control of upper and lower sealing elements with separate indication of both temperatures;
• High quality pneumatic cylinders ensure stable pressure on samples during the test;
• Multi-layer sample can also be tested precisely;
• Easy operation and maintenance;
• Wide time setting range with adoptable time controller;
• Durable components;
• Built in printer to print reports;
• LCD touch screen;
• Advanced embedded electronic system ensures that the pre-set temperature is reached without fluctuations or delays;

Operation

• Place the layers of material to be sealed between heating elements;
• Set the compressed air pressure for applying load;
• Set Temperature of heating element and test duration using LCD touch screen;
• Automatic completion of test and display of test results;
• Test results can be printed using embedded printer.
