Abstract
The invention relates to a nontacky film-forming polymer composition (cover material), and tacky hot melt adhesives in the form of pellets which are coated with the polymer composition and producible by coextruding the hot melt adhesive and the cover material. The film-forming composition comprises 5 to 40% by weight of at least one Fischer-Tropsch wax having a melting point of >95° C. and 30 to 70% by weight of at least one metallocene-catalyzed polyolefin having a softening point of >95° C. and a melt flow index (MFI) (230° C., 2.16 kg) of ≤1000 and ≥300 g/10 minutes. The invention further relates to suitable uses for such hot melt adhesives, methods for their use, and products containing these adhesives.
