Abstract
A composite container for storing perishable products may include a composite body and a composite bottom. The composite bottom may include a bottom fiber layer, a bottom oxygen barrier layer, and a bottom sealant layer, such that the composite bottom has an upper surface and a lower surface. A hermetic seal may be formed between a sealing portion of the composite bottom and an interior surface of the composite body. When an internal pressure is applied to the interior surface of the composite body and the upper surface of the platen portion of the composite bottom, an external pressure is applied to the exterior surface of the composite body and the lower surface of the composite bottom, and the internal pressure is about 20 kPa greater than the external pressure, the platen portion of the composite bottom may not extend beyond the bottom edge of the composite body.
