An blow-extrudable film that ensures a reclosing ability after a first opening consists of a support layer on which a connecting layer and an overlying cover layer are arranged. The connecting layer essentially consists of a pressure sensitive hot melt adhesive. Both the support layer and the cover layer are essentially composed of polyethylene.
