Aluminum foil has high sealing and oxidation resistance, and its air permeability is low, which can ensure that the gas inside the package does not leak, so as to ensure the integrity of the package and prevent the internal gas from being affected by the external environment. Therefore, it is very important to test the air permeability of aluminum foil of cigarette packs.
Cigarette pack aluminum foil gas transmittance tester is commonly used to test the air permeability of cigarette pack aluminum foil testing equipment, the following from the test principle, application scope and other aspects of the detailed introduction.
Test principle of cigarette pack aluminum foil gas transmittance tester:
Using the differential pressure test principle, the pre-treated specimen is placed between the upper and lower test chambers and clamped. The low-pressure chamber (lower chamber) is first vacuumed, and then the entire system is evacuatedWhen the specified vacuum degree is reached, the lower chamber of the test is closed, and the high-pressure chamber (upper chamber) is filled with a certain pressure of test gas, and a constant pressure difference (adjustable) is formed on both sides of the sampleIn this way, the gas will penetrate from the high-pressure side to the low-pressure side under the action of the differential pressure gradient, and the internal pressure of the low-pressure side will be monitored and processed to obtain the various barrier parameters of the tested sample.
Importance of the application of the cigarette pack aluminum foil gas transmittance tester:
1.Improve quality consistency. Detecting the air permeability of cigarette pack aluminum foil is an important index for evaluating cigarette pack aluminum foil. By using this one, the quality of cigarette pack aluminum foil can be better ensured and its quality stability can be improved.
2.R&D process improvement. By using the pen, you can have a deeper understanding of the product characteristics of cigarette pack aluminum foil, explore the best manufacturing process and formula, and provide strong support for the further improvement and development of the product.
3.Comply with the requirements of the standard. By using this equipment, it can help enterprises ensure that their products meet the requirements specified in the standard, thereby improving production efficiency.
4.Increase productivity. By using this equipment, the labor cost in the production process can be better reduced, so as to improve the production efficiency.
Cigarette pack aluminum foil gas transmittance tester is an important equipment to evaluate the quality of cigarette pack aluminum foil, through the use of this equipment, can better ensure the quality of cigarette pack aluminum foil products, improve production efficiency.
