Laminate with an area having improved tear resistance

A laminate (10) has at least two plastic films (28, 30) bonded together by means of an adhesive layer (32), with at least one area (B) having reduced adhesion strength to improve the tear resistance, in which area (B) at least one varnish layer (36) is arranged between a first plastic film (28) and...

More Information
Summary:A laminate (10) has at least two plastic films (28, 30) bonded together by means of an adhesive layer (32), with at least one area (B) having reduced adhesion strength to improve the tear resistance, in which area (B) at least one varnish layer (36) is arranged between a first plastic film (28) and an adjacent adhesive layer (32), thereby reducing the adhesion. The at least one varnish layer (36) is formed by a pattern having a plurality of surface elements (37a) locally reducing the adhesion strength between the first plastic layer (28) and the adhesive layer (32), or by a continuous pattern interrupted by a plurality of surface elements (37a) locally reducing the adhesive strength between the first plastic film (28) and the adhesive layer (32).
