Container Gas Permeability Tester

Product catalog summary

Overview: The GHS-03 Gradient Heat Seal Tester is designed to evaluate the heatsealability of various films and materials under specific conditions of speed, pressure, and temperature. It is particularly useful for testing plastic films, composite films, and coated papers.

Professional Technology:

Utilizes digital P.I.D temperature control for rapid and stable temperature achievement.
Offers a wide range of control over temperature, pressure, and time to accommodate different testing conditions.
Features manual or pedal switch control and an anti-scald design for safe operation.
Controlled by a micro-computer with an LCD and PVC operation panel for user convenience.
Capable of testing five groups of specimens at different temperatures simultaneously.
Equipped with individually controlled upper sealing jaws and easily replaceable heating tube joints.
Includes a micro-printer for data saving, exporting, and printing.

Test Standards: Conforms to ASTM F2029, QB/T 2358, YBB 00122003 standards.

Applications:

Basic Applications: Suitable for films with smooth surfaces, including various plastic and composite films, and aluminum foils.
Films with Decorative Patterns: Applicable to films with patterns, including geomembranes and aluminum foil composites.
Extended Applications: Can be customized for jelly cup covers and plastic flexible tubes.

Catalog excerpts

I PARAM® GHS-03 Gradient Heat Seal Tester GHS-03 Gradient Heat Seal Tester is professionally designed for the determination of heatsealability of plastic films, composite films, coated paper, and other sealing films under certain sealing speed, pressure and 5 different temperatures. The heatsealability of heat sealing materials would be greatly affected by the factors of melting point, thermal stability, fluidity and thickness. The properestheatsealability parameters could be obtained accurately and efficiently through this instrument. Professional Technology • Digital RID temperature control technology ensures preset temperature to be reached rapidly without any • Wide range control of temperature, pressure and time could meet various test conditions. • Manual or pedal switch control, as well as anti-scald design provides convenient and safe operating • The instrument is controlled by micro-computer with LCD, PVC operation panel, and menu-interface, which • The instrument could test 5 groups of specimens at different temperature simultaneously, and accurately and efficiently obtain heatsealability parameters of the tested specimens. • 5 upper sealing jaws are individually controlled by 5 gas cylinders which ensure the stability of heat sealing • The heating tube joints can be easily installed or removed for rapid replacement. • Independent temperature control of upper and lower sealing jaws gives multiple combinations of test • Equipped with micro-printer for convenient data saving, exporting and printing. Test Standard This test instrument conforms to the following standards: ASTM F2029, QB/T 2358, YBB 00122003 The instrument is professionally applicable to the determination of heatsealability of: 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 user requirements. Instrument could simultaneously perform sealing operations at 5 different temperatures.

Surface aluminum foil composite films and many others. Heat sealing surface can be designed based on user requirements. Instrument could simultaneously perform sealing operations at 5 different temperatures. 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 overs of Jelly Cups mould whose size exactly fits jelly cup. Put the jelly cup in the mould of lower jaw, and sealing operation can be finished by upper jaw pushing. (Customization required) Plastic Flexible The end of plastic flexible tubes is placed in between...
