摘要： A package comprises a flexible film (22) defining an interior contents cavity and having a first pair of edge portions forming a first seal (38), a second pair of edge portions forming a second seal (36), and a longitudinal seal (40) extending from the first seal (38) to the second seal (36). A score (24) is formed in the flexible film (22) and defining, at least in part, an opening to the interior contents cavity. A closure layer (26) covers the score (24) and a portion of the flexible film around the score, the closure layer (26) extending over more than half of a width of the flexible film. A pressure sensitive adhesive lies between the closure layer (26) and the flexible film (22). The package is opened along the score (24) by partial removal of the closure layer (26) from the flexible film (22) and the extension of the closure layer over more than half the width of the flexible film resists further removal of the closure layer from the flexible film.

摘要： A resealable closure (11) for a container in which package integrity is indicated by a structure (40) which connects the closure (11) to a remaining portion of the container which must be broken in order to gain access to the contents of the container for a first time. The package integrity feature, in one form, includes a structure (40) associated with the closure, wherein upon opening the closure for a first time, the structure stretches, increasing a length of the structure until the structure eventually breaks, leaving one or both residual ends of the broken structure rippled or curved upward from the remainder of the container. In one alternative form, the structure is associated with a pull tab of the sealing panel, which comprises the closure, whereby either the structure must be broken first, prior to pulling back the sealing panel, or while pulling back the sealing panel for a first time, the structure breaks, prior to gaining access to the contents therein. Advantageously, the package integrity feature is integrally formed with the closure and a remaining portion of the container. Integrity of the package is indicated by visually observing an intact breakable structure.
