　　Packaging nitrogen permeability testerIt is a professional testing equipment based on the principle of differential pressure testing, used to evaluate the nitrogen barrier performance of packaging materials. The working process is as follows: the sample is placed between the upper and lower testing chambers and clamped. The low-pressure chamber (lower chamber) is first vacuum treated, and then the entire system is vacuumed. After reaching the specified vacuum degree, the testing lower chamber is closed, and a certain pressure of nitrogen gas is filled into the high-pressure chamber (upper chamber) to form a constant pressure difference on both sides of the sample. Nitrogen gas permeates from the high-pressure side to the low-pressure side under the pressure gradient. By monitoring and processing the pressure inside the low-pressure side, parameters such as the nitrogen gas permeability of the sample are obtained.
This instrument has multiple technical features, such as the use of imported high-precision vacuum sensors and high-quality vacuum pumps, which can achieve accurate testing of ultra-high barrier materials; The device has powerful functions and can not only test the permeability of nitrogen, but also the permeability of other gases such as oxygen and carbon dioxide; Capable of independent testing chamber design, with multiple options including three chamber and six chamber, providing efficient sample testing; Equipped with professional operating software, it can intuitively display detailed test data, support computer control and automatic testing, and is easy and fast to operate; The instrument structure design is reasonable, and the material selection is excellent, which can ensure the stability and reliability of long-term use.
The importance of packaging nitrogen permeability tester:
Ensuring product quality and safety: In the food industry, nitrogen, as a protective gas, can extend the shelf life of products. By detecting the nitrogen permeation rate of packaging materials, the sealing performance of packaging materials can be evaluated, ensuring that food is not affected by external gases during storage and transportation, and maintaining its original quality and taste. In the pharmaceutical field, for some drugs that are extremely sensitive to oxygen and moisture, such as antibiotics, vitamin tablets, biologics, etc., nitrogen is often filled into the packaging as a protective gas. This instrument can accurately measure the nitrogen barrier performance of composite films, ensuring that packaging materials can effectively prevent nitrogen leakage, maintain the nitrogen concentration inside the packaging, and protect drugs from oxidative damage.
Meeting industry standards and regulatory requirements: Its test results can serve as an important basis for evaluating the quality of packaging materials, helping enterprises meet relevant regulations, standards, and regulatory requirements at home and abroad. For example, China's drug packaging material standards (such as YBB series standards) clearly stipulate the gas permeability testing methods and index requirements for packaging materials such as infusion bags.
Guidance on material selection and improvement: Test results can provide valuable data support for enterprises, helping them understand the performance differences between different materials and guide material selection and improvement. For example, companies can adjust the formula and process parameters of composite film materials based on test results to reduce nitrogen permeation rate and improve packaging performance.
Promoting the application of new technologies: As a pioneering material barrier performance testing device, its application will continuously drive the application and development of new technologies in related fields.
