Plastic barrier containers protect food products from oxygen and other environmental agents for a year or more at ambient temperatures This protection relies on the use of a barrier polymer in the multilayer structure To predict the bar rier performance of a container, it is important to use permeability data for the bar rier polymer that is accurate and reflects actual polymer processing and use condi tions. This paper shows that the barrier performance of Saran* vinylidene chloride (VDC) copolymers in rigid containers is much better than has been previously re ported. © 1990, Sage Publications.
