Abstract:
1. A bag comprising: a tube body having a first end, a second end positioned substantially opposite the first end, a front wall positioned between the first end and the second end, and a back wall positioned to face opposite the front wall between the first end and the second end, the front wall having at least one outermost layer of porous material; a back flap extension member connected to and extending outwardly from the second end of the back wall, the back flap extension member being adapted to fold over, overlie, and adhere to selected second end portions of an outer surface of the front wall when in a closed position to thereby securely close the second end; a primer material positioned on and overlying selected portions of an outer surface of the front wall to thereby define a first bond region between the front wall and the primer material, the primer material also defining a liquid surface treatment on the outer surface of the front wall to penetrate into the outermost layer of porous material to promote further bonding; and an adhesive material positioned on and overlying the back flap extension member to thereby define a second bond region between the primer material and the adhesive material when the back flap extension member is folded over the selected second end portions of the outer surface of the front wall and the adhesive material contacts the primer material.
