Abstract The present invention relates to a coextrusion binder comprising:5 to 30 parts of a polymer (A), itself comprising a blend of a polyethylene (A1) of relative density between 0.935 and 0.980 and of a polymer (A2) chosen from elastomers, very low-density polyethylenes and ethylene copolymers, the (A1)+(A2) blend being cografted with an unsaturated carboxylic acid;95 to 70 parts of a polyethylene (B) of relative density between 0.930 and 0.950. This binder is particularly useful for petrol tanks.
