Abstract

A hotmelt composition comprises at least three co-polymers defined by their chemistry and molecular weight. The hotmelt composition may be without tackifiers. The hotmelt can be used in absorbent articles such as diapers comprising two substrates at least partially attached by the hotmelt composition. The hotmelt provides especially good nonwoven-nonwoven bond and nonwoven-film bond.
