The differential pressure method is a widely used technique to measure gas permeability. It involves creating a pressure difference across the material and measuring the rate at which gas diffuses through it. This method is particularly suitable for materials with relatively high oxygen permeability, such as those used in heat patch inner packaging.
Labthink C106H Gas Permeability Test System is a specialized instrument designed for measuring gas permeability. It operates based on the differential pressure principle and is compliant with international standards like GB, ISO, and ASTM. This system offers precision and reliability in determining the oxygen transmission rate of various materials, including heat patch inner packaging.
In this study, a sample of non-woven fabric used as the inner packaging for a heat patch was subjected to oxygen permeability testing using the C106H system. The test results revealed an oxygen transmission rate of 7.634 × 10⁷ cm³/(m²·24h·0.1MPa). This information provides valuable insights into the material's ability to allow oxygen to pass through while maintaining the desired heat patch performance.
Oxygen permeability is a critical factor in ensuring the optimal performance of heat patches. By understanding the oxygen transmission rate of the inner packaging material, manufacturers can fine-tune the design and composition of their products to achieve the desired temperature and duration of heat delivery. The C106H Gas Permeability Test System offers a reliable and efficient method for assessing this important property, enabling the development of high-quality heat patches that meet consumer needs.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
