Abstract: A bottom gusset bag includes a gusset connecting a front and rear panel. The side regions of the front and rear panels are sealed to each other in a pair of side seams in a manner such that when the bag is unfilled it is flattened and when the bag is filled it is substantially a six-sided cubic shape with the bottom of the filled bag formed of the bottom gusset being substantially flat. The bottom gusset bag further includes a side handle that includes a strip of material exterior of the gusset with the ends of the handle joined to each pair of side seams. The handle extends along an exterior surface of the bag from a first side seam along an exterior surface of the rear or front panel to a second side seam.

Abstract: A bottom gusset bag includes a bottom gusset connecting a front and rear panel. The side regions of the front and rear panels are sealed to each other in a pair of side seams in a manner such that when the bag is unfilled it is flattened and when the bag is filled it is substantially a six-sided cubic shape with the bottom of the filled bag formed of the bottom gusset being substantially flat. The bottom gusset bag further includes a handle that includes a strip of material interior of the bottom gusset with the ends of the handle joined to each pair of side seams. Further, the bottom gusset bag can include weakened portions in the bottom gusset on opposing sides of the handle that, when broken, expose holes for a hand or fingers to enter the bottom gusset and wrap around the internal handle for carrying the bottom gusset bag with the bottom facing upwards.

Abstract: A method is provided for protectively packaging sterilizable materials. A product to be packaged is placed within a semi-rigid, foldable packaging tray to form a package insert. The package insert is then placed within a heat-sealable container, such as a polymeric film envelope. Vacuum force is applied to evacuate the vacuum sealable container and to seal the packaging insert within the vacuum sealable container. The vacuum sealed container may then be placed within an outer, flexible packaging container and heat sealed therein. The entire package is generally sterilized after heat sealing within the outer, flexible package.
