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.

摘要翻译： 描述了用于包装的柔性层压板，其包括集成的单向阀，其允许在包装内产生的气体（例如，二氧化碳废气）被释放到外部环境，同时防止环境元件进入包装 。 该阀由形成柔性层压体的层限定，而不是作为连接到柔性层压体的单独结构。 特别地，第一和第二切割线以偏移方式限定在柔性层压结构的第一和第二膜层的阀区域中。 油被图案施加到阀区域中的一个或两个膜层，并且一个或两个膜层的相对表面还包括减少膜层之间的表面能量的表面处理，以允许阀打开 在所需的压力下。
