The invention relates to a tear band (1) for packages comprising distinguishing markings. To counter piracy, especially of brand products, the invention aims to provide packaging with a tear mechanism which presents an opening and closing possibility that is specific to the manufacturer and suitable for determining whether the package has been opened or not. To this end the invention provides for a tear band (1) which before it is joined to the packaging film (2) is stretched at least in sections on the left and/or right side, and/or on the upper side and/or on the lower side, which stretching serves as coding. The number and/or radii and/or height of the waves of the tear band (1) present after tearing constitute coded information. According to a different version of the invention a tear band (1) for packaging is provided with one or more perforated holes (5) serving as coding. According to the invention the tear band (1) is also provided with at least one optically active security element for coding information, which element consists of at least one characteristic colour, a diffracting structure and/or a metallized coat.
