<p>The chocolate wrapper consists of a sheet of paper support with an aluminium coating on outer side. On the front of the wrapper are two cross seams, and near the braking line of the chocolate is positioned a longitudinal seam. The cross seams and the longitudinal seam are forming sealed or glued seams. In at least the longitudinal seam (11), the glue (4) is present on at least one of the two edge strips (8, 9) of the wrapping (10) and on only one part of the surface forming the closing seam. The glue is deposited in the form of a number of small wave shaped strips (7) which cross each other. In the direction across the sealing or gluing seam are two strips (7) between which is enclosed a non sealing or non gluing surface (6).</p> |
