Claim:
1. A method for producing successive packaging units where each packaging unit includes a single-dose packaging for transdermal therapeutic systems or forms of administration in foil form, in the form of a tear-open sealed-edge pouch including a product receiving region enclosing a packaged product, the tear-open sealed edge pouch also including a non-peelable completely surrounding and continuous sealing area or sealing seam, the tear-open sealed-edge pouch also comprising first and second packaging material elements, which are arranged with the first packaging material element lying on top of the second packaging material element and respectively forming the upper side and underside of the tear-open sealed-edge pouch which contains the product, at least one layer of the packaging material elements including a metal layer and at least one of the first and second packaging material elements being a foil laminate having an at least three-layered structure including an outer layer, a middle layer and an inner layer, and the outer layer of the at least three-layered foil laminate having a minimum resistance to tearing of 30 Newtons, the outer layer having at least one line of weakness, not touching the peripheral edge of the packaging, congruently on the upper side and underside of this outer layer and the at least one line of weakness having a reduced resistance to tearing for the opening of the packaging, the at least one line of weakness colinear with a bending line, the product receiving region has a protuberance reaching into the sealing area, the at least one line of weakness runs both through the sealing area and through the product receiving region in the protuberance, the protuberance not running the entire length of one side of the product receiving region, comprising the steps of: providing the first packaging material element or sheet having an at least three-layered foil laminate structure with the outer, tear-resistant layer of the multi-layered foil laminate structure; providing the second packaging material element or sheet; positioning the packaged product on one of the two packaging material sheets; laying the two packaging material sheets one on top of the other and joining them in such a way as to form for any packaged product the tear-open sealed-edge pouch for receiving the packaged product that is enclosed on all sides and at the peripheral edge or edges of which the two packaging material elements are unreleasably joined to one another; providing the at least one line of weakness by removing either uniformly or intermittently the outer, tear-resistant layer of the multi-layered foil laminate, the at least one line of weakness running both through the sealing area and through the product receiving region in the protuberance, the protuberance not running the entire length of one side of the product receiving region; individually separating successive packaging units by a cut or a perforation along a line which runs transversely in relation to the sheet direction of the packaging material sheets in the region of the sealing area.
