The front and rear panels extend above the middle panel and a second adhesive strip between the front and rear panels extends between terminal ends at the first bag side edges. A release liner is provided over the adhesive strips and retaining the bags open for placing product therein. By removing the release liner, the first bag is closed with the adhesive strip between the front and rear panels and the second bag is closed with the adhesive strip between the middle and rear panels.
