CONTAINER, VACUUM PACKAGE, AND PACKAGING PROCESS Abstract of the Disclosure The invention disclosed is directed to an improved sealable container which comprises a wall including a wall region having opposed first and second flexible wall portions, a check valve integral with the wall and including an openable port disposed in the wall region, and at least one elongate section of sealed engagement of the first wall portion with the second wall portion. The port and spaced sealed section define a fluid flow path extending from the container exterior adjacent the port to an interior zone of the container, the path being substantially sealable against fluid flow, and the wall being characterized with low permeability respecting water vapor, air, and air components. The con- tainer is highly suitable for maintaining subatmospheric pressure within packages, also disclosed, which may be formed of the container with a product therein. A process for vacuum packaging is further disclosed.
