Barrier Film Water Vapor Transmission Rate Testing Service

Film Heat Shrinkage Tester tests various heat shrinkage properties for the film according to the principle of air heating (air bath). Suitable for heat shrinkable films which produced with polyethylene, ethylene copolymers and their mixtures, such as beverage labels, bottled bundle packaging, sausage shrinkage packaging, outer film of daily chemical products, outer film of cigarette boxes, etc. It is a device that can accurately and quantitatively measure the thermal shrinkage force, cold shrinkage force, shrinkage rate, shrinkage time and other properties of plastic films during thermal shrinkage. The test results have a variety of data, which can evaluate the heat shrinkage performance of the film from different aspects, contribute to the research and development of heat shrinkable films of different materials, ensure the stability of heat shrinkable films performance of various materials, and meet the requirements of various heat shrinkable films in various industries. GBPI checks the key thermal shrinkage properties of film products for you. The traditional oven or oil bath equipment only detects the heat shrinkage rate of the heat shrinkable film, and the test results are relatively limited. Our Film Heat Shrinkage Tester GBK-D1 can evaluate the thermal shrinkage performance of films from various data. It is easy to operate, environmentally friendly, with high data accuracy and more comprehensive test results to meet your requirements.

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.
