Abstract:
1. A reclosable pouch having a valve, comprising: opposing sidewalls; first and second opposing layers of a film material disposed across a full width of one of the sidewalls, an overlap region of the second layer overlapping the sidewall, the first layer being attached to the second layer around a portion of the second layer, the second layer being sealed to the sidewall around a periphery of the overlap region, and opposing surfaces of the first and second layers forming a substantially airtight seal therebetween upon direct contact of the layers; and first and second offset apertures extending through the first and second layers, respectively, one of the first and second apertures being in fluid communication with an interior of the pouch and the other of the first and second apertures being in fluid communication with an exterior of the pouch; wherein vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the pouch.
