摘要： A flexible laminate for a package is described that includes an integrated one-way valve that allows gas generated within the package (e.g., carbon dioxide outgas) to be released to the external environment, while at the same time preventing environmental elements from entering the package. The valve is defined by the layers that form the flexible laminate, as opposed to being a separate structure that is attached to the flexible laminate. In particular, first and second cut lines are defined in a valve area of the first and second film layers of the flexible laminate structure in an offset manner. Oil is pattern-applied to one or both film layers in the valve area, and an opposing surface of one or both of the film layers further includes a surface treatment that decreases the amount of surface energy between the film layers to allow the valve to open at the desired pressure.

摘要： The present invention relates to a resealable container comprising: a polyethylene terephthalate-based container body comprising a bottom side and at least one upwardly extending sidewall, wherein the sidewall terminates in an open end of the container; a flexible film sealed to the container body, over the open end of the container, wherein the flexible film comprises: a polyethylene-based first film layer; a pressure sensitive adhesive layer adjacent a lower surface of the first film layer; a polyolefin plastomer skin layer adjacent a lower surface of the pressure sensitive adhesive layer, wherein the first layer, pressure sensitive adhesive layer, and skin layer are coextruded; and a heat seal layer printed onto a lower surface of the skin layer and heat sealed to the container body.
