More Information
Summary:Adhesive propylene polymer composition suitable for extrusion coating of paper substrates is disclosed. Two-component adhesion composition suitable for extrusion coating paper substrates which comprises a) from 70 to 98 wt % of high melt strength polypropylene (A) with a branching index g' of 0.9 or less and b) from 2 to 30 wt % of a component (B) selected from the group of (i) maleic anhydride-modified polypropylene (MAPP) (ii) maleic anhydride-modified polypropylene wax (iii) polypropylene homopolymer with high melt flow rate or (iv) ethylene-vinyl acetate-based hot melt adhesive and its use.
