Abstract: Easy open flow wrappers are provided that include a flexible wrapper body formed from a flexible wrapper body film, the flexible wrapper body having a front panel and a back panel sealed together along one longitudinal seam and two lateral end seams containing a product therein. At least one line of weakness (24) substantially extends around a portion of the flexible wrapper body to define a removable portion (28) of the flexible wrapper body, such that application of a separation force upon the removable portion separates the removable portion from the flexible wrapper body at the at least one line of weakness and forms an opening in the flexible wrapper body. A flexible film member (26) is disposed over and extending beyond the at least one line of weakness, in which the flexible film member is configured to prevent pre-separation of the removable portion from the flexible wrapper body.

Abstract: An easy open package is provided including a package body formed from a flexible film having a pair of transverse end seals (114, 116) and a longitudinal seal (112) generally therebetween. The longitudinal seal (112) includes a sealed region between a first longitudinal edge portion of the flexible film sealed to a second longitudinal edge portion of the flexible film. A tear strip (118) and pull tab (122) formed in the package body are configured such that initiation of a tear by pulling the pull tab (122) in one direction causes controlled tearing of the flexible film along the line of weakness (120) defining the tear strip (118). Flexible films and methods for fabrication of the flexible films and packages also are provided.
