A pouch style containment and dispensing package for flowable products is provided. The package comprises at least three layers of thin materials selected from a group of materials including heat sealable plastic films, metal foils, oxygen barrier films, plastic moisture barrier films, adhesives, coextrudable plastics and high strength plastics. The package includes an aperture or aperture forming means and a flap portion that is folded over and sealed to cover the aperture or aperture forming means, so that when the flap portion is folded back and away, an aperture is exposed or created. The layers may be selected so that a contact face of the flap member is sealed at a lower temperature than a sealing temperature for forming edge seals on the inner product contacting wall layers. Also, one layer may comprise a high strength layer that will not lose a significant amount of strength at temperatures substantially higher than the edge sealing temperature. Also, the invention provides a pouch style package having a pre-formed bulge in at least one wall to increase its product containment capability.
