Abstract (en)
[origin: WO2022263063A1] The present invention relates to the use of a laminate comprising a) at least one metal foil, the metal foil having a thickness of 3 to 250 μm, and b) a sheet-like substrate, comprising a nonwoven having a ratio of ultimate tensile strength, determined according to ISO 9073-3: 1989(E), lengthwise to crosswise, of 1:2 bis 2:1, where the laminate has an ultimate tensile strength, determined lengthwise and/or crosswise, according to ISO 9073-3: 1989(E), in the range from 50 to 800 N/5cm and an elongation, determined lengthwise and/or crosswise, according to ISO 9073-3: 1989(E), of less than 30%, for shielding electromagnetic rays.
