count of using proprietary blends of polymers characterized by high water vapor transfer rates (WVTR), the packaging eliminates excess moisture (Fig. 5). Excess moisture is conducive for decay and will often necessitate repacking. Different polymers are used for different applications based on sensitivity to moisture and dehydration and the permeability of the film is manipulated to provide optimum gas compositions for the produce and weight to be packed.
