A patented, rapid, accurate, and reliable method for measuring CO2 permeation and sorption in packaging materials.
Coventional methods for measuring CO2 permeability in packages essentially measure changes occurring in the package CO2 content during a simulated shelf-life test. Such tests are inherently slow because it takes a long time to see a measurable change in CO2 content. Also inherent in such methods is the challenge of having to measure very small changes (often less than 10%) in package CO2 levels accurately over extended time periods. Further, since these tests take so long to complete they are also of little use in predicting shelf life of a packaged batch of product.
