Abstract: According to the standard of GB/T 2918, this article attempts to give a detailed explanation on the influence of test environment on physical property of flexile package. Test environment in this article refers to the lab environment for physical property testing of flexible package such as film, not including special environment used for some unusual testing and material or the simulating of specified climate condition. Generally speaking, it mainly refers to the following three indexes: ambient temperature, humidity and flow rate of lab air cycling. Among that, temperature and humidity have significant influence on testing result of physical property of flexible polymer material. Products & Services
Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.
Property testers are used to determine various physical properties of samples, including distillation, vapor pressure, and cloud, flash, freezing, melting, or pour point.
Environmental test equipment services for environmental test chambers, reactors, baths, incubators, laboratory ovens and furnaces, and vibrational shakers. Services may include repair, calibration, upgrading, rebuilding, installation, training and replacement.
Thermal management design and analysis services perform tests and redesigns around thermal dissipation issues.
Hardness testers measure a material's resistance to indentation. This calculation is determined by measuring the permanent depth or projected area of the indentation.
