Many packaged products are sensitive to moisture. Therefore, control of water vapor into or out of the package is critical to the contained product’s quality. The permeability of packaging materials has a direct effect on a packages performance in terms of the contained products shelf-life. This permeation by moisture is measured by WVTR (water vapor transmission rate) or MVTR (moisture vapor transmission rate). The primary purpose of packaging is to get the packaged product to the customer in one piece and suitable for consumption. Packaging plays many roles, containing and protecting products during distribution, storage, and use, while also promoting, educating, and selling.
