Abstract: A composite packaging foil for a childproof and/or senior friendly packaging, including a first layer having a first outer surface and a first inner surface, wherein the first layer imparts tear-inhibiting properties to the packaging foil, a second layer having a second outer surface and a second inner surface, wherein the second outer surface of the second layer is sealable against a mating surface, an inner layer arranged between the first inner surface of the first layer and the second inner surface of the second layer. The packaging foil has at least one weakening zone in which the tear-inhibiting properties of the packaging foil are reduced by a plurality of perforations that are present in the first layer. The density of perforations in the weakening zone lies between 50 and 250, preferably between 50 and 150 and particularly preferred between 70 and 130 perforations per cm2.
