Abstract: A gastight valve strip for a reclosable container includes first and second film layers adapted to be disposed over an aperture through a sidewall of a reclosable container. The second film layer opposes the first and includes an attachment surface adapted to be sealed to the sidewall of the container. The attachment surface has a patterned portion that defines a region of flow channels. Opposing surfaces of the first and second film layers form a substantially gastight seal therebetween upon contact of the first and second film layers to each other. A first film layer aperture extends through the first film layer, and is in fluid communication with an exterior side of the valve strip. A second film layer aperture extends through the second film layer, is offset and spaced apart from the first film layer aperture, and is in fluid communication with the container aperture through the patterned portion.

Abstract: A gastight valve strip for a reclosable container. The valve strip includes opposing first and second film layers adapted to be disposed over a container aperture through a sidewall of the reclosable container. The first film layer is attached to the second film layer by a first thermal seal disposed around the periphery of the first film layer. An attachment surface of the second film layer is adapted to be sealed to the sidewall of the reclosable container. Opposing surfaces of the first and second film layers form a substantially gastight seal therebetween upon contact of the film layers. Offset first film layer and second film layer apertures extend through the first and second film layers, respectively, the first film layer aperture being in fluid communication with an exterior side of the valve strip and the second film layer aperture being configured to be in fluid communication with the container aperture.

Abstract: A reclosable pouch includes first and second film layers disposed on a first pouch sidewall. The first film layer is attached to the second film layer by first and second intermittent spot seals disposed at least across respective first and second edges of the first film layer. The second film layer is sealed to the sidewall by third and fourth intermittent spot seals disposed at least across respective third and fourth edges of the second film layer. Offset first and second apertures extend through the first and second film layers, respectively, wherein one of the first and second apertures communicates with a pouch interior and the other of the first and second apertures communicates with a pouch exterior. A fifth intermittent spot seal is disposed between the first and second film layers, the fifth intermittent spot seal surrounding a region including the first and second apertures.
