Abstract: A packaging material made of a support layer of aluminum and a lacquer layer applied onto the support layer with excellent opening behavior. The lacquer of the lacquer layer consists of a solvent, a binder, and a plasticizer. A polymer binder with a molecular weight of at least 80,000 Dalton, preferably at least 100,000 Dalton, is used, and by virtue of the mixing ratio between the solvent, the binder, and the plasticizer, a bond strength between the lacquer layer and the support layer ranging from 0.07 N/50 mm to 0.30 N/50 mm and an elongation at break of the lacquer layer of at least 150% are set.
