Abstract of the Disclosure A vacuum package is made of flexible laminate capable of being stored at roll stock. The laminate comprises laminated inner and outer layer providing desired mechanical properties, secured together at patterned areas to facilitate the pasage of gas between the layers, and is provided with a hand peelable sealing strip at an area which, when the laminate is formed into a bag and the mouth sealed, extends around the periphery of the mouth of the package. When the laminate is formed into a bag, the application of vacuum to the interior of the bag results in the inner layer conforming to the contours of the contents, while ambient air between the layers enables the outer layer to maintain a desirable and aesthetically pleasing smooth surface texture.
