OTR Testing of Aluminum Plastic Composite Bags

The oxygen barrier properties of packaging materials are crucial to maintaining the quality and shelf life of packaged products, especially when dealing with perishable goods like food. This article discusses the testing of oxygen transmission rates (OTR) in aluminum plastic composite film packaging bags used for food packaging.



The coulometric method was employed to measure the OTR of the packaging bags. This method involves creating a concentration difference between high-purity oxygen on one side of the sample and high-purity nitrogen on the other. As oxygen permeates through the material, it is detected by a coulometric sensor, allowing for a precise measurement of OTR.



Labthink C230H Oxygen Transmission Rate Test System was used for the testing. This instrument is designed to accurately measure the OTR of various materials, including plastic films, sheeting, paper, and packages. It features a high-precision coulometric sensor, temperature and humidity control, and a user-friendly interface.

The OTR of the aluminum plastic composite film packaging bags was found to be 0.2346 cm³/pkg·24h. This value indicates the rate at which oxygen penetrates the packaging.

The oxygen barrier properties of packaging materials are essential for ensuring the quality and safety of food products. The coulometric method, as employed in this study, provides a reliable and accurate means of measuring OTR. Labthink C230H Oxygen Transmission Rate Test System is a valuable tool for researchers and quality control professionals in the food packaging industry. By understanding the OTR of packaging materials, manufacturers can select appropriate materials and optimize packaging designs to preserve product quality.

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...
