Punched article, in particular for permanently closing holes

A diecut for the permanent closing of holes in metal sheets or in plastics parts, the diecut comprising:

• a carrier composed of an assembly laminate in the specified layer sequence, of
• at least one first layer having a thickness of 1 to 6 mm, wherein the at least one first layer is a needlefelt web comprising mechanically needled, oxidized and thermally stabilized polyacrylonitrile (PAN) fibers and the needlefelt web is a tuft of PAN fibers made into a sheetlike structure comprising barbs,
• at least one second layer formed by a pressure-sensitive adhesive in the form of a laminating adhesive having a unit area coat weight of 5 to 50 g/m2,
• at least one third layer formed by a woven glass fabric or laid glass fabric having a basis weight of 30 to 200 g/m2,
• optionally at least one fourth layer formed by a pressure-sensitive adhesive in the form of a laminating adhesive having a unit area coat weight of 5 to 50 g/m2,
• at least one fifth layer formed by a metallic layer having a thickness of 5 to 40 μm, and
• at least one sixth layer formed by a further, acrylate-based pressure-sensitive adhesive having a basis weight of 300 to 1800 g/m2.
