1. A package comprising:
a multilayer film with a first film layer and a second film layer having an embedded coextruded bonding layer therebetween, the first film layer having a first cut formed therein, the first cut extending from the first film layer at least to the embedded coextruded bonding layer and the second film layer having a heat seal layer and a release and reclose layer for resealability, the multilayer film configured such that the release and reclose layer is disposed adjacent the embedded coextruded bonding layer;
a base film adhered to the first film layer of the multilayer film via an adhesive lamination layer configured such that the multilayer film and the base film form a multi-ply multilayer film with a non-adhering zone between the base film and the multilayer film and the first cut does not extend into the base film or through the heat sealable layer;
an outer cut disposed in the base film and extending therethrough and the outer cut extending to or at least partially through the embedded coextruded bonding layer and a portion of the outer cut coincides with the non-adhering zone to form, in part, a pull tab; and
an inner cut disposed inwardly from the first cut and the outer cut, the inner cut extending from the second film layer and at least to the embedded coextruded bonding layer;
wherein the package has a resealable opening formed with a reseal margin defined, in part, by the first cut and a resealable panel defined, in part, by the outer cut and the resealable opening defined, in part, by the inner cut.
