1. A flexible laminate for shielding against electromagnetic radiation, comprising:
a) at least one metal foil; and
b) a sheet-like substrate comprising a fiber material, film material, or foam material,
wherein the laminate comprises a plurality of objects formed by incisions into a base area of the laminate,
wherein each object of the plurality of objects comprises two or more incisions having a common initial point, and
wherein the two or more incisions, or each of two adjacent incisions of the two or more incisions, define an angle of 45° to 160°, and
wherein each incision of the two or more incisions completely perforates the at least one metal foil and completely perforates the sheet-like substrate.
