Abstract
A reclosable package includes a pair of opposing walls, a reclosable seal and a barrier partition. The pair of opposing wall panels are joined along a pair of opposing sides and a bottom bridges the opposing sides to create a receptacle space having a mouth end opposite the bottom. The reclosable seal extends along the mouth end and includes first and second opposing reclosable elements. The first and second reclosable elements are releasably engageable to each other. The barrier partition comprises at least a first layer that is substantially impermeable to at least one of oxygen, nitrogen and carbon dioxide. The barrier partition extends substantially across the pair of opposing wall panels in the receptacle space.
