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.

Note1: There are five upper sealing jaws and five lower sealing jaws for heat seal test. The temperature of all the sealing jaws can be controlled independently. All of the sealing jaws are heated sealing jaws. The unheated sealing jaws can be selected as lower sealing jaws.
This test instrument conforms to the following standards: ASTM F2029Note2, 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.
The instrument is professionally applicable to the determination of heatsealability of:
|Basic Applications|| |
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.

|Extended Applications|| |
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 jelly cup. Put the jelly cup in the mould of lower jaw, and sealing operation can be finished by upper jaw pushing. (Customization required)
The end of plastic flexible tubes is placed in between upper and lower jaws and then sealed to form a package.
