Abstract: The invention relates to a blister top foil for sealing with respect to an existing blister bottom foil, wherein the blister top foil comprises at least the following layers, seen from the outside to the inside of the finished pack: possibly a layer of printing undercoat lacquer (c), a layer of printing primer (d), a layer of adhesive (e), a layer of plastic film (f), a layer of possibly peelable adhesive (g), a layer of aluminum (h) and a layer of heat sealing lacquer (i). The invention is characterized in that the printing primer layer (d) is an aluminum layer.

Abstract: The invention relates to a pack in the form of a stick or cushion, consisting of one or two sheets (7, 7?), which has at least one aluminum layer facing the contents and one layer, which faces away from the contents, is areally connected to the aluminum layer and is made of polyethylene terephthalate (PET layer) or other materials, having a tear-open aid in one of the outer surfaces, which comprises a weakening line in the PET layer. The invention is characterized in that the tear-open aid has at least two weakening lines (4, 5), the point of intersection of which in the outer surface lies at a distance from the nearest edge of the pack, and in that the angle between the weakening lines at the point of intersection is between 60° and 90° .
