Water Vapor Transmission Rate Test Of Plastic Films-soojin

Marketing Plastic films have been widely applied in various industries such as food, agriculture, packaging, biochemistry, etc. The water vapor transmission rate is the most important factor which could influence the quality of the package of plasctic films and hence influence the product quality. So it has become a focus of the manufacturers of plastic films for the water vapor transmission rate test. Labthink Instruments Co.,Ltd has developed most advanced and precise instruments which could be used for the test of water vapor transmission rate to ensure the water permeability of plastic films meet the requirements. Labthink supplies differnet models which may be suitable for different customers. Labthink W3/330 Water Vapor Transmission Rate Test System is applicable in water vapor transmission rate testing for plastic films, laminated films, sheets, solar energy back sheets, high barrier materials, foils, OLED, water-proof membranes and bottles, pouches, jars, boxes made of plastic, rubber, paper, glass and metal, as well as medical devices, etc. With water vapor transmission testing, controlling and adjustment of packaging materials can be achieved; application demands can also be satisfied. The testing principle of water vapor transmission rate tester is as follows: Mount the preconditioned specimen between the testing cells and clamp tightly. Nitrogen with constant humidity flows in one side of specimen; dry nitrogen flows in another side of the specimen. Owing to the humidity difference, water vapor passes through the specimen from higher humidity side and enters the lower humidity side, and is carried to the sensor by the dry nitrogen. The electrical signals are generated; water vapor transmission rate and other parameters can be obtained by analyzing the electrical signals. For packages, dry nitrogen flows in the packages, high humidity nitrogen flows around the outer side of the package. For more information, please visit Labthink website and send us inquiries.
