Oxygen, for example, causes adverse reactions in many foods such as potato chips. By measuring the rate at which O2permeates through the package material, one can begin to determine the shelf-life or amount of time the unopened package will still provide ‘good’ chips.

    Permeation measurements are crucial to targeting a package’s sweet spot. This sweet spot is defined as the intersection between effective marketing, product protection and cost. When all three areas combine, a functional, cost-effective package that meets its shelf life requirements is developed.However, the product protection segment is often overlooked and can have a significant impact on the other segments, especially the cost. Learn More...
