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!

Moisture Resistance Testing of Thermal Conductive Silica Gel Pads

Thermal conductive silica gel pads, crucial components in electronic devices, require effective moisture resistance to ensure optimal performance and longevity. This article delves into a comprehensive testing method for evaluating the water vapor transmission rate (WVTR) of these pads. Electronic components are sensitive to moisture, which can lead to corrosion, short circuits, and reduced reliability. Thermal conductive silica gel pads, often used to facilitate heat dissipation between electronic chips and radiators, play a vital role in preventing moisture ingress. Their moisture resistance properties directly impact the protection of sensitive internal components. The electrolytic sensor method, a widely recognized standard, is employed to measure the WVTR of thermal conductive silica gel pads. This technique involves creating a controlled environment with a high humidity chamber on one side and a low humidity chamber on the other. A sample of the thermal conductive silica gel pad ...

Quality Requirements of Lithium Ion Battery Separators

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Introducing Vacuum Decay Testing Method for Pharmaceutical Packaging Integrity

Maintaining the integrity of pharmaceutical packaging is fundamentally essential for safeguarding product efficacy and patient safety, and vacuum decay testing stands as a highly reliable non-destructive method for verifying this integrity. This technique, particularly effective for blister packs, vials, and pre-filled syringes, identifies leaks without compromising product sterility or efficacy. Vacuum decay testing leverages the principle that a sealed package, when subjected to a vacuum, will exhibit predictable pressure changes if it's leak-free. Conversely, a leaking package will show a different pressure profile. Specific Vacuum Decay Techniques: Differential Pressure Transducers: These precise sensors measure the difference in pressure between the vacuum chamber and a reference chamber. This allows for detection of very small leaks. Absolute Pressure Sensors: These sensors measure the absolute pressure within the vacuum chamber, providing data to determine the rate of pres...
