Abstract:
Improved packages and methods for constructing packages are provided that reduce or prevent leakage into or out of the package. In particular, the package includes a base member and a lidding member with a reinforced perimeter portion that blocks channels that may form at the interface between the base member and the lidding member from extending to the edge of the base member, such that, e.g., liquids have no path to the package exterior. The perimeter portion may be a thicker region of a first film of the lidding member (e.g., a polyethylene emulsion), or the perimeter portion may be formed using permanent adhesive. Frangible layers and/or cut lines may be defined in the material of the base member or the lidding member to allow a controlled break to occur when the lidding member is peeled away from the base member to provide access to the package contents.
