Abstract

A layered structure that includes at least a first layer and a second layer is provided. The second layer includes at least one barrier layer. A bonding substance is partially disposed between the barrier layer and the first layer to create a bond between the barrier layer and the first layer. The bonding substance contains a first component that has, at 25° C., a shear modulus of not more than 3×105 Pa in accordance with the Dahlquist criterion. The bonding substance may also contain a second component having adhesive characteristics. The first component also has a low viscosity such that a force (F) between the first and second layers which acts on at least one of the layers in a force action area is distributed by a plastic flow onto an area which is larger than the force action area.
