The main function of the inner coating is to serve as a barrier between the ointment and the external environment, preventing contamination, oxidation, or deterioration of the ointment. By detecting the continuity of the inner coating, it can be ensured that the coating has no defects such as voids, cracks, or peeling, thereby maintaining the barrier performance of the ointment tube. This is crucial for maintaining the stability of the ointment and extending its shelf life.

Introduction to the Continuity Tester for Inner Coating of Aluminum Medicinal Ointment Tube

The continuity tester for the inner coating of aluminum medicinal ointment tubes is a detection device used to check the continuity index of the inner coating of aluminum medicinal ointment tubes. The specific basis is YBB00162002-2015 "Aluminum Medicinal Ointment Tubes". The medicinal compound ointment tube is mainly used to hold all kinds of creams, gel and ointments of ointment. It has the characteristics of corrosion resistance, no leakage, excellent air tightness, safety, hygiene, beautiful appearance, exquisite printing, convenient use and green environmental protection. It is an ideal choice for pharmaceutical enterprises. The testing requirements of the internal coating continuity tester are that it can complete the testing of the internal coating continuity index of aluminum medicinal ointment tubes. It is a laboratory testing equipment for quality inspection departments, manufacturers, and pharmaceutical factories.

Principle of Aluminum Medicinal Ointment Tube Internal Coating Continuity Tester

Fill the hose coated with oil with a test solution containing copper sulfate, immerse a sliding electrode in this solution, and the hose itself is in contact with a base electrode with a V-shaped groove. Then apply a constant 5 ± 0.5V DC current between the sliding electrode and the hose, and the current conducted is proportional to the surface area of the aluminum tube not covered by the coating. If the coating is discontinuous, the copper sulfate electrolyte reacts due to the effect of electrolytic current, and black deposited copper appears at the leakage point of the inner coating, which can clearly indicate the size of the exposed area of the inner coating.

The Importance of Continuous Coating Tester for Aluminum Medicinal Ointment Tube

1. Prevent drug leakage and contamination

If there are continuity defects in the inner coating, the ointment may leak out through these defects, or external pollutants such as moisture and air may seep into the ointment tube, causing contamination of the ointment. By detecting and repairing these defects, drug leakage and contamination can be prevented, ensuring that the ointment used by patients is safe and effective.

2. Meet the requirements of drug packaging regulations

In the field of drug packaging, each country has strict regulations and standards to ensure the quality and safety of drug packaging. Testing the continuity of the coating inside aluminum medicinal ointment tubes is an important requirement in these regulations and standards. Through testing, it can be ensured that the ointment tube meets the requirements of relevant regulations and standards, thereby avoiding legal risks and compliance issues.

3. Improve the overall quality of the ointment tube

The continuity of the inner coating is an important indicator of the overall quality of the ointment tube. By detecting and improving the continuity of the inner coating, the sealing, barrier, and durability of the ointment tube can be enhanced, thereby increasing its market competitiveness.

In summary, testing the continuity of the inner coating of aluminum medicinal ointment tubes is an important measure to ensure the quality of the ointment tubes, meet regulatory requirements, enhance market competitiveness, and ensure patient medication safety.
