CLASSIC 513 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 optimal heatsealability parameters can be obtained accurately and efficiently through this instrument.

Product Features

• P.I.D. temperature control technology ensures preset temperature to be reached rapidly without any fluctuation.
• 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 environment.
• The instrument is controlled by micro-computer with LCD, PVC operation panel, and menu-interface, which is convenient for customers.
• The instrument could test 5 groups of 2 specimens at different temperatures 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 process.
• The heating tube joints can be easily installed or removed for rapid replacement.
• Independent temperature control of upper and lower sealing jaws allows multiple combinations of test conditions.
• Equipped with micro-printer for convenient data saving, exporting and printing.

Test Standard

This test instrument conforms to the following standards: ASTM F2029^Note2, QB/T 2358, YBB 00122003
Note2: The 10 sealing jaws are all heated sealing jaws as required by ASTM F2029. If necessary, the lower sealing jaws can be replaced with unheated sealing jaws.
