Comprehensive Testing Scheme of Solid Preparation Composite Sheets

Solid preparation composite sheets, primarily composed of materials like PVC, PE, and PVDC, are indispensable in the pharmaceutical industry for blister packaging. These sheets directly interact with medications, making their quality paramount. To ensure product integrity and efficacy, rigorous testing is essential.

A critical aspect of quality control is evaluating the sheet's barrier properties. This involves measuring water vapor transmission rate (WVTR) and oxygen transmission rate (OTR). These tests determine the sheet's ability to protect drugs from moisture and oxygen, preventing degradation, discoloration, and other quality issues.

C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.

Mechanical properties are equally important. Tensile strength and elongation at break indicate the sheet's resistance to tearing and stretching during handling and packaging. These properties are crucial for preventing product damage.

Heat sealing strength is another critical factor. The integrity of the seal formed between sheets is vital for product containment.

Finally, impact resistance is essential to ensure the sheet can withstand accidental drops or bumps during transportation and handling.

By adhering to established standards and conducting comprehensive testing, manufacturers can ensure the quality and reliability of solid preparation composite sheets. This, in turn, guarantees the safety and efficacy of the packaged medications. Investing in robust quality control measures is not just a compliance requirement but a fundamental aspect of protecting public health.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
