ABSTRACT:
The invention concerns a coextrusion binder comprising a mixture of at least one ethylene homo- or copolymer (A1) of density ranging between 0.940 and 0.980 g/cm3with at least one propylene homo- or copolymer (B), said mixture being grafted by at least one functional monomer and optionally diluted in at least one non-grafted ethylene homo- or copolymer (A2) of density ranging between 0.940 and 0.980 g/cm3; the grafting rate of said coextrusion binder being less than 0.5% wt. % based on the total weight of said binder; the density of said tie ranging between 0.940 and 0.980 g/cm3. The invention also concerns a structure comprising said type of binder as well as its use.
