ABSTRACT:
The present invention relates to hotmelt adhesive compositions which comprise at least one thermoplastic polyolefin (P) which is solid at 25° C., and also at least one amide (A) of the formula (I) or (II).These hotmelt adhesive compositions are suitable more particularly for the adhesive bonding of polyolefin films. More particularly it is possible to form assemblies of a substrate (S) and polyolefins bonded with a hotmelt adhesive.
