1. A laminate comprising first and second spunbonded nonwoven layers wherein at least one spunbonded nonwoven layer comprises or consists essentially of crimped continuous filaments that are bicomponent filaments of core-sheath configuration and having a first component based on polypropylene and a second component based on polypropylene, a specific density ρ in g/cm3 of the spunbonded nonwoven laminate depending on the surface density of the spunbonded nonwoven laminate lying below a density limit ρG defined by the following equation:
ρG=9 cm−1×surface density g/cm2+0.0393 g/cm3.
