A foil made of two plastic films and an adhesive layer laminating the two films together, wherein the first plastic film has a first side and a second side and comprises punctures therebetween. The foil is of a dual peel-seal type such that the first plastic film realizes a first peel-able seal within the foil at its first side in the form of an adhesion peel seal in an open state and/or in the form of a cohesion peel seal in a sealed state, and wherein the adhesive layer leaves open the punctures such that gas can penetrate through the punctures in-between the two films towards the first peel-able seal.

In a reclosable bag () a zipper (Z) is provided on the inner surfaces () of the plastic film and the two parts of the zipper (Z) are fixed on the opposite inner surfaces () of the bag (), wherein the zipper (Z) is connected to the inner surface () of the plastic film in such a manner that between the welded regions () between the zipper (Z) and the inner surface () of the plastic film, recesses () are left free in the longitudinal direction of the zipper (Z) to form a seal-free longitudinal channel and in the transverse direction of the zipper (Z) to produce free air or steam passage openings at defined distances between the zipper (Z) and the inner surface (), through which openings a passage of steam is possible, wherein ends of the openings facing the interior () of the bag () are larger than ends of the openings facing the exterior () of the bag ().

In a method of manufacture for a packaging film, a pour-hole film strip is supplied to a film web and with its film strip sealing layer is attached to that side of the film web which, when the packaging film is used as prescribed, forms a film inner side of the packaging so that a tensile force can be transmitted via a pull tab in the packaging film to a separating region in the film strip sealing layer and said separating region and an adjoining region of an adhesive layer form a reclosure cooperating with the pull tab.
