Abstract
A laminate is provided made of two film materials with different tear resistance values, particularly made of polyester and polyethylene. The part of the laminate made from a film material with a high tear resistance is structured in multiple layers and has at least two layers made from this high tear resistance material connected with one another by an adhesive layer with a low shear resistance. This structure results in a laminate having improved tear resistance.
