Before the tear-off strip (1) is connected to the packaging film, it is stretched in sections on the left and/or right, on the upper (7) and/or lower side (6). This stretching serves as coding. Number and/or radii and/or height of the waves created before connection and after tearing-open, show coding of information. The tear-off strip may also have a number of punched perforations (5), which may represent company logos or trademarks. The strip may also have metallised sections, and within these sections, numbers or letters are non-metallised. |
