Product catalog summary

Integral Package Barrier Property Testing: Ensuring Package Quality

Introduction: Traditionally, barrier property testing focused on films, leaving a gap in data for finished packages, potentially leading to quality issues. Recent advancements in integral package barrier property testing have addressed these concerns.

Testing Methods:

Equal Pressure Method: Suitable for various packages like bottles and pouches, this method uses a test gas and a carrier gas to measure transmitted gas and determine barrier properties.
Differential Pressure Method: Ideal for measuring gas transmission rates, though it requires techniques to maintain package shape under pressure differences.
Weighing Method: A traditional method for water vapor transmission using a desiccant, but it has limitations such as long testing times.
Sensor Method: A faster, automated alternative to the weighing method, using sensors to measure water vapor transmission under controlled humidity.

Importance of Testing: Integral package barrier property testing is crucial for:

Selecting appropriate materials to protect products from external elements.
Optimizing package design to ensure proper sealing and minimize leaks.
Predicting shelf life to estimate product quality maintenance.
Identifying potential failures to detect weak spots in packaging.

Conclusion: Integral package barrier property testing provides valuable insights into the performance of finished packages, helping manufacturers ensure product quality and shelf life, ultimately benefiting consumers. Labthink encourages collaboration with packaging industry companies for quality control.

Integral Package Barrier Property Testing Ensuring Package Quality-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Integral Package Barrier Property Testing Ensuring Package Quality 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.  Differential Pressure Method: This method is ideal for measuring transmission rates of various gases but requires special techniques to maintain package shape under pressure differences. Weighing 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. Sensor 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.
