Printed markings are applied to the sealing strip (5) at even distances. The distance (D) between neighbouring markings is the same as the repeat length of the strip. This in turn corresponds to the circumference of the largest package (P) to be wrapped, plus overlap. A strip-like coating, esp. of adhesive, is applied to the strip at a constant set distance in front of each marking, and at right angles to the longitudinal direction of the strip. This is for the closing the strip loops. |
