Patch usually contains oxygen sensitive ingredients. If the oxygen permeability of the packaging material is too high, these ingredients may react with oxygen, leading to drug deterioration, reduced efficacy, and even the production of harmful substances. Therefore, by testing the oxygen permeability of packaging materials, it can be ensured that drugs maintain their original quality and efficacy during storage and use.

Principle of Oxygen Transmittance Tester for Adhesive Packaging Materials

The processed sample is clamped onto the testing chamber, with oxygen or air flowing on one side of the membrane and high-purity nitrogen flowing on the other side of the membrane. Oxygen molecules diffuse through the membrane into the high-purity nitrogen on the other side and are carried by the flowing nitrogen to the sensor. By analyzing the oxygen concentration measured by the sensor, oxygen permeability test data is obtained after reaching permeation equilibrium.

Application of Oxygen Transmittance Tester for Adhesive Packaging Materials

1. Extend the shelf life of drugs

Oxygen is one of the main factors causing drug oxidation, and oxidation accelerates the deterioration process of drugs. By reducing the oxygen permeability of packaging materials, the contact between oxygen and drugs can be reduced, thereby extending the shelf life of drugs. This is particularly important for patches that require long-term storage or transportation.

2. Compliant with regulatory requirements

In the process of drug production and sales, drug regulatory agencies in various countries usually impose strict requirements on the performance of packaging materials, including restrictions on oxygen permeability. Therefore, testing the oxygen permeability of patch packaging materials is also to meet the requirements of relevant regulations, ensure the legality and market competitiveness of drugs.

3. Enhance user experience

Patch is usually used for skin treatment, and its quality and safety directly affect the patient's experience and treatment effect. By ensuring that the oxygen permeability of packaging materials is within a reasonable range, discomfort and side effects caused by drug deterioration can be reduced, and patient satisfaction and trust can be improved.

In summary, testing the oxygen permeability of patch packaging materials is of great significance for ensuring drug quality, extending shelf life, complying with regulatory requirements, improving user experience, and guiding packaging design. Therefore, in the production and sales process of patches, high attention should be paid to the oxygen permeability testing of packaging materials.
