A reclosable film package for storage of solid or liquid food products using a straight-tear film package having a zipper. The straight-tear films allow for tearing of the film along straight lines without perforating or laser scoring of the film allowing optimal integrity of the package and product

1. A reclosable film package comprising:a) first and second overlapping straight-tear films capable of propagating a tear along a locus of points in one of two substantially straight perpendicular lines in response to an applied force sufficient to propagate a tear in the films, the films being sealed together at top, bottom, left and right edges defining an enclosure, the enclosure having sealed bottom, left and right margins extending for a distance away from the bottom, left and right edges toward a center of the films; each film comprising in order from an outside portion of the enclosure to an inside portion of the enclosure: i. a nylon or polyester layer; ii. optionally, an adhesive layer; and iii. a sealant layer; b) a reclosable zipper substantially parallel with and positioned below the top edge of the films and extending between left and right end points located at the left and right margins; said zipper comprising a first track on the first straight-tear film and a second track on the second straight-tear film, which first and second tracks are adapted to releasably engage each other; c) a slider moveably attached to said tracks for engaging and disengaging the tracks between the end points; d) left and right nodules positioned at the left and right end points; and e) a tear propagation line extending from the left nodule to the right nodule substantially parallel along the zipper, and a tear propagation line extending from each of the left and right nodules substantially parallel along the left and right margins to the top edge of the films, defining a removable tear strip between the left and right margins and above the zipper.
