Abstract:
1. A method of forming a reclosable seal for a package, the method comprising: heat-sealing a first edge to form the reclosable seal by contacting a first seal segment to a second seal segment and sealing to each other such that a heat seal is formed in a region between a first layer of the first seal segment and a third layer of the second seal segment where the first seal segment is an inner lap seal segment and the second seal segment is an outer lap seal segment; wherein the package has a first layer, a second layer having a pressure sensitive adhesive, and a third layer throughout, where the heat seal strength between the first and third layers is greater than the heat seal strength between the second and third layers, and the heat seal strength between the second and third layers is greater than the heat seal strength between the first and second layers and is effective to permit the first layer to separate from the second layer of one of the first seal segment and the second seal segment upon opening, at the region of the heat seal to expose the pressure sensitive adhesive of the second layer and oriented away from a package interior.
