Barrier Testing and Comparison in Pouch Package Structures, 2005 PLACE Conference

PressWeb.jpg

Various methods may be used to estimate the oxygen and moisture barrier of flexible pouch packaging. A series of experiments was designed to compare the practical barrier of pouches. Foil was used as the control and compared to metallized oriented polypropylene. These experiments were intended to simulate flexing and handling that would be expected through the conversion and distribution chain. Barrier data was collected at various stages in order to estimate and compare the potential degradation of initial barrier through practical usage. In one set of experiments, Gelbo flex testing was used to simulate handling. In the second set of experiments pouches were filled with desiccant, subjected to a protocol of shipping and dropping, and weight gain measured over time.
