The packaging composite film has an outside and an inside. It also includes a cover layer facing the outside, an inner layer, which faces the inside and has a lower puncture and tear resistance than the cover layer, and a liquid-soluble intermediate layer arranged between the cover layer and the inner layer. To transport liquid from the outside to the liquid-soluble intermediate layer, liquid-transporting openings are provided, which completely penetrate the cover layer and extend in the direction of the inside at least to the intermediate layer, without including the inner layer. A childproof packaging, which is nevertheless easy to open and therefore senior-friendly, can be realized by means of the packaging composite film. |
