Abstract
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.
