Barrier testing is only valuable when you can trust the results — and the validation behind them.
Understand how modern permeation testing — including oxygen transmission rate (OTR), water vapour transmission rate (WVTR/WTR), and low-barrier film analysis — can help you improve accuracy, validate sustainable materials, and make confident decisions across films, structures, and finished packaging.
Whether you work in R&D, quality control, or packaging development, this guide shows how to move from uncertainty to verifiable confidence in barrier testing.
What you’ll discover in this guide:
- How modern permeation testing (OTR, WVTR/WTR) improves accuracy and decision-making
- How to support sustainable materials and validate barrier performance
- Why calibration and validation are critical for reliable results
- How to move from material testing to full package validation
- Ways to improve efficiency and reduce testing variation
- How data supports shelf-life and compliance decisions
- Overview of testing solutions for films, materials, and finished packaging
- Options for both routine QA and high-throughput production environments
