Gas Transmission Rate Testing For Packaging Material

Product Introduction GBB-C vertical heat seal tester can accurately measure the heat sealing temperature, heat sealing time, heat sealing pressure, and other heat sealing performance parameters of plastic packaging vertical bags, paper-plastic composite vertical bags and metal composite vertical bags(boxes). The heat sealing performance of samples of different materials are different. And the best heat sealing conditions can be accurately obtained through the determination of their heat sealing performance parameters.   Testing Principle Put the sample on the lower tray of the instrument, adjust the appropriate height according to the size of the sample, set a certain sealing temperature, time and pressure as required, and start the instrument with one key. The fixture on the instrument will heat seal the sample according to the setting parameters. Under the manual state, step on the foot switch, and the heat sealing knife is pressed. The heat sealing time is determined by the value set by the time control. In the automatic state, the upper and lower heat sealing knives of the heat sealer will automatically heat seal repeatedly according to the set time.

Spectrophotometer ST50 is a spectrophotometer developed by GBPI series core technology, using built-in photodiode array (double 20 groups) sensors, imported whiteboard, while taking into account the measurement speed and convenience of operation. The repeatability delta E* AB of ST50 spectrophotometer is easily controlled within 0.03, and the Inter-instrument error delta E* AB is controlled within 0.2, to make the measurement more accurate. And the test data can be used for accurate color analysis and transmission in the laboratory. Application  Spectrophotometer ST50 is equipped with one customized measuring aperture, accurate color measurement and stable performance. It is used for accurate color measurement and quality control in plastic electronics, paint ink, textile and garment printing and dyeing, printing, ceramics and other industries, and can be used for fluorescent sample measurement.   Features  1. Large area photodiode array (dual 20 arrays) sensor  A larger area of double 20 array sensor, strong light saturation, weak light sensitivity and a wider spectrum response range, to ensure the instrument measurement speed, accuracy, stability and consistency, independent core technology, and international standards of the same platform, to achieve complete compatibility. 1. Adopt D/8 structure and SCI/SCE mode  Spectrophotometer ST50 uses a widely international use D/8 optical structure, SCI/SCE (Specular Component Included/Specular Component Excluded) synthesis technology, support SCI+SCE at the same time fast measurement, test time about 1.5 seconds.  2. Combination of full spectrum LED light source and UV light source The use of 400-700nm full spectrum LED light source ensures sufficient spectral distribution in the visible light range, avoiding the spectral loss of specific bands, strong light will not be saturated, weak light is more sensitive, and fluorescence samples can be easily measured. 4. Camera positioning can clearly observe the measured area  The ST50 spectrophotometer has built-in camera. Through the real-time scene-taking of the camera, it can accurately determine whether the measured part of the object is the target center, which improves the measurement efficiency and accuracy.

The Coefficient of Friction Tester equipment performs tests to most of the recognised international test standards including IS0 8295 and ASTM 1894-78.
