The quality control significance of packaging oxygen barrier performance and the principle and application of oxygen permeability

The quality control significance of packaging oxygen barrier performance refers to the barrier effect
of packaging materials on gas, liquid and other permeates.
Barrier performance testing includes two types of
gas (oxygen, nitrogen, carbon dioxide, etc.
) and water vapor permeability.
Barrier performance is an important factor affecting the quality of products during the shelf life, and is also an important reference for analyzing the shelf life, through which the detection can solve the problems
of oxidative deterioration, moisture and mildew caused by sensitivity to oxygen or water vapor.
Oxygen can cause a series of oxidative deterioration problems of food, such as hara flavor in the content of food, oxidation to acid, etc.
, so the oxygen barrier performance test of packaging is very important
.
ISOBARIC-401 oxygen transmittance tester oxygen permeability device working principle products are based on coulombic oxygen analysis sensor and isobaric test principle, with reference to ASTM D3985 standard design and manufacturing, for high and medium gas barrier materials to provide high precision and high efficiency oxygen transmittance detection test
.
It is suitable for oxygen transmission performance testing
of films, sheets, packaging and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic electronics, etc.
The pre-treated sample is clamped between the test chambers, 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 into the high-purity nitrogen on the other side, and are carried to the sensor by the flowing nitrogen, and the oxygen transmittance rate is calculated by analyzing the oxygen concentration measured by the sensor; For packaging, high-purity nitrogen flows inside the package, with air or oxygen surrounding the outside of
the package.
Application scope of oxygen permeability equipment Basic application: film - oxygen transmittance test
of various plastic films, paper-plastic composite films, co-extrusion films, aluminized films, aluminum foil composite films, glass fiber aluminum foil composite films and other film materials.
