The present disclosure relates to a flexible film package having an adhesive based reclosable fastener. A flexible film substrate forms a plurality of package walls joined to one another to form an interior cavity for receiving a product. The plurality of walls have at least first and second opposing flexible walls and the second opposing flexible wall extends beyond the first opposing flexible wall. A first low tack pressure sensitive adhesive (LTPSA) layer is disposed on an exterior surface of the first opposing flexible wall. A second LTPSA layer disposed on an interior surface of the second opposing flexible wall on a portion that extends beyond the first opposing flexible wall. The LTPSA layers are configured to be adjacent to one another when the package is closed along a fold line. A package mouth is oriented between the first and second LTPSA layers, initially sealed, to permit access to the interior cavity.
