Testing Challenges of High Barrier Materials

Product catalog summary

Introduction
High barrier materials are increasingly used in packaging due to their superior performance. Testing these materials poses specific challenges, necessitating careful selection of testing instruments.

Challenges of Testing High Barrier Materials

Low Gas Transmission Rate: Requires instruments with excellent sealing and highly sensitive sensors.
Long Equilibrium Time: Instruments must have stable system zero and minimal environmental interference to achieve stable readings.

Key Instrument Selection Criteria

Sealing Performance: Instruments must have excellent seals and proper specimen clamping to prevent leakage.
Sensor Precision: Essential for accurate measurement of low gas transmission rates.
System Zero Stability: Consistency is crucial to minimize errors.
Environmental Controls: Instruments should monitor and control temperature, humidity, and vibration.

Specific Considerations for Different Testing Methods

Differential-pressure Method: Instruments should have a low testing limit, high vacuum degree, and environmental control capabilities.
Equal-pressure Method: Focus on low testing limit, environmental controls, and gas source handling.
Weighing Method: Automated instruments with low testing limit and vibration monitoring are preferred.
Sensor Method: Electrolytic sensors are more stable than infrared sensors; environmental controls are important for infrared sensors.

Conclusion
Accurate testing of high barrier materials requires careful instrument selection and proper testing procedures. Addressing factors like gas source, specimen sealing, and environmental conditions is crucial. Labthink offers various testers and encourages collaboration with the packaging industry for quality control.

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Choosing the Right Instrument for High Barrier Material Testing High barrier materials are becoming increasingly popular in packaging due to their excellent performance. However, testing these materials presents unique challenges. This article explores the key considerations for selecting instruments to test high barrier materials. Challenges of Testing High Barrier Materials • • Low gas transmission rate: This necessitates instruments with exceptional sealing performance and highly sensitive sensors. Long time to reach equilibrium: Reaching stable readings can take hours, requiring instruments with stable system zero and minimal environmental interference. Key Instrument Selection Criteria • • • Sealing performance: Leakage is a major concern, so instruments need excellent seals and proper specimen clamping techniques. Sensor precision: Highly precise sensors are crucial for accurate measurements of low gas transmission rates. System zero stability: Consistent system zero minimizes errors, especially for high barrier materials. Environmental controls: Temperature, humidity, and vibration can significantly impact results. Choose instruments that can monitor and control these f
