ABSTRACT:
A sealable container (20) includes an inner wall (24) formed of a semipermeable sheet material and shaped into an inner bag (30), an outer wall (26) formed of a gas impermeable sheet material and shaped as an outer bag (32), with a gas space (28) therebetween. A product, e.g. ground coffee (22), is heat sealed under vacuum in the inner bag (30) and gas is introduced into the gas space (28) via openings (56) in the outer bag (32). The container is then heat sealed again to isolate the openings (56) from the gas space (28), to prevent ambient air from gaining ingress to the product. The finished package has a smooth exterior appearance.
