Composite structures comprising one or more substrates and an adhesive blend comprising blends of a non-elastomeric graft copolymer of a non-polar ethylene homopolymer or copolymer backbone grafted with at least one grafting monomer comprising one or more of polymerizable ethylenically unsaturated carboxylic acids or the anhydrides of such acids blended with an elastomer-free blending resin that is a mixture of one or more linear low density polyethylenes and one or more polypropylenes.
