Paper-plastic composite film is a kind of packaging material composed of paper and plastic film, which has the advantages of excellent mechanical properties, moisture resistance, transparency, barrier properties and aesthetics. It is more and more widely used in the field of packaging and has become an important packaging material. It can be used not only for the outer packaging of the product, but also for the inner packaging and cushioning materials, etc.
The oxygen permeability of paper-plastic composite film is an important parameter to evaluate the quality of paper-plastic composite film, so it is very important to detect its oxygen permeability parameters.
Detection principle of oxygen permeability tester for isobaric oxygen permeability tester of paper-plastic composite film:
The treated sample is clamped on the test chamber, oxygen or air flows on one side of the film, high-purity nitrogen flows on the other side of the film, oxygen molecules diffuse through the film to the high-purity nitrogen on the other side, and the flowing nitrogen is carried to the sensor, and the oxygen concentration measured by the sensor is analyzed, and the oxygen permeability test data is issued after reaching the osmotic equilibrium.
The importance of the application of the paper-plastic composite film isobaric oxygen transmittance tester:
It can ensure that the products packaged can maintain good quality and safety. Paper-plastic composite film is commonly used in the packaging of food, medicine and other products, which require a certain oxygen content during production and storage to maintain their quality and nutritional value.
Therefore, testing the oxygen permeability of paper-plastic composite film can ensure that the packaged products can be stored and transported in a suitable oxygen content environment to maintain their good quality and efficacy. At the same time, it can also avoid product deterioration and other problems caused by insufficient oxygen permeability of packaging materials, so as to protect the rights and interests of consumers and health and safety.
Summary. By using the isobaric oxygen permeability tester of paper-plastic composite film, the product quality of paper-plastic composite film can be effectively ensured, which plays a very important role in the production of enterprises.
