A pouch with a valve includes first and second pouch sidewalls sealed to one another to define an opening. A resealable closure mechanism is attached to inner surfaces of the first and second sidewalls proximate the opening to define a pouch interior opposite the opening. A channel extends from the interior to the opening between a section of the first closure element and the first sidewall. A pleated thermoplastic member is sealingly disposed in the channel and has an aperture disposed through the member. A fluid path may provide direct fluid communication between the interior and an exterior of the pouch, wherein the fluid path passes through an edge of the pouch defined by at least one of the first or second pouch sidewalls. A valve is sealingly disposed in the fluid path, wherein the valve comprises a pleated thermoplastic member attached to at least one of the first or second pouch sidewalls and having an aperture disposed through the pleated thermoplastic member to provide fluid communication between the interior and the exterior of the pouch.

We claim: 1. A pouch, comprising:first and second pouch sidewalls sealed to one another to define an opening;a resealable closure mechanism attached to inner surfaces of the first and second sidewalls proximate the opening to define a pouch interior opposite the opening;a channel extending from the interior to the opening through the closure mechanism when the closure mechanism is sealed; anda check valve disposed across the channel between the closure mechanism and the opening, wherein the check valve comprises a first protruding surface on the first sidewall that sealingly engages with a second protruding surface on the second sidewall such that when the closure mechanism is sealed the check valve allows air to be evacuated from the interior through the channel and prevents air from entering the interior through the channel and the protruding surfaces comprise intermeshing complementary first and second corrugated cross sections of the first and second sidewalls.
