Principle
The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1 Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination. GBPI Film Shrinkage tester conforms to the multiple national and international standards: ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of shrinkage stress and contraction stress DIN 53369 - Testing of plastic films determination of the shrinking stress Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on. Principle This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23 to cool down. The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film. Standards ISO 14616, ASTM D2732, DIN 53369
Water Vapor Permeability Tester is manufactured based on the gravimetric method, and is applicable to test the water vapor transmission rate of plastic films, composite films, sheets and other materials used in packaging, medical and constructive industry. Features Standard periodic weighing method and auto-zeroing function guarantee the accuracy and uniformity of the testing data. Touch interface is more convenient to operate. The test data is reliable due to the automatic process and the weighing system controlled by the gas cylinder. Innovative circulating dehumidification system with built-in vacuum pump can effectively prevent the formation of humidity gradient and ensure the accuracy. High-precise and automatic control system of temperature can be used under different conditions. The data can be stored and outputted in multi-format (including report in excel and cloud sharing). The rapid calibration mode with standard weight-counter is provided. GMP management of user's three-level authority complies with international standard. The instrument processes statistical analysis of single and group data. Equipped with ISP control online and upgrade function. Specialized communicating software can display in real-time, analyze and store data. Principle Under a certain temperature, the constant difference of humidity is generated between two sides of the test specimen. The water vapor permeates through the specimen and gets into the dry side. By measuring the weighing changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.
