Integral Package Barrier Property Testing Ensuring Package Quality

Keywords: Complete Container, Entire Finished Package Seal and Overall Barrier Properties and Functionality from Oxygen & Moisture

Traditionally, barrier property testing was limited to films, leaving manufacturers and users of finished packages with limited data on the actual performance of their products. This gap led to potential quality issues. Thankfully, advancements in integral package barrier property testing have addressed this concern.

There are three main testing methods for integral packages:

Equal Pressure Method: This method is suitable for various packages, including bottles, pouches, and blisters. It works by introducing a test gas (like oxygen) on one side of the package and a carrier gas on the other. The sensor measures the amount of transmitted gas to determine the package's barrier property.

žDifferential Pressure Method: This method is ideal for measuring transmission rates of various gases but requires special techniques to maintain package shape under pressure differences.

žWeighing Method: This traditional method for water vapor transmission involves placing a desiccant inside the package and monitoring weight changes over time. However, it has limitations like long testing times and the need to open the package.

žSensor Method: This method offers a faster and more automated alternative to the weighing method. It utilizes a sensor to measure water vapor transmission through the package wall under a controlled humidity environment.

Integral package barrier property testing plays a crucial role in ensuring package quality. By measuring gas and water vapor transmission rates, manufacturers can:

žSelect appropriate materials: Choose packaging materials that effectively protect the product from external elements like oxygen, moisture, or contaminants.

žOptimize package design: Ensure proper sealing and minimize leaks that could compromise product quality.

žPredict shelf life: Estimate how long a product will maintain its quality within the packaging.

žIdentify potential failures: Detect weak spots in the package that could lead to product spoilage or degradation.

In conclusion, integral package barrier property testing offers valuable insights into the performance of finished packages. By employing various testing methods and instruments, manufacturers can ensure the quality and shelf life of their products, ultimately benefiting consumers.
