Abstract: The present invention relates to a coated article comprising at least a substrate layer (SL), a first coating layer (CL1) and a second coating layer (CL2), wherein CL2 comprises a polypropylene composition comprising (A) a polypropylene homopolymer having a melt flow rate MFR2 (230° C./2.16 kg) measured according to ISO 1133 in the range from 10 to 40 g/10 min; a melting temperature Tm as determined by DSC according to ISO 11357 in the range from 149 to 162° C.; and a molecular weight distribution MWD in the range from 2.4 to 4.5 as determined by GPC; and/or (B) an ethylene propylene random copolymer having a melt flow rate MFR2 (230° C./2.16 kg) measured according to ISO 1133 in the range from 4 to 40 g/10 min; a melting temperature Tm as determined by DSC according to ISO 11357 in the range from 115 to 145° C.; and a number of 2,1 and 3,1 regio defects in the range from 0.01 to 1.2 mol-% as measured by 13C NMR; and wherein SL and CL1 are polypropylene-based layers. Furthermore, the present invention refers to a process for manufacturing the coated article and to its use. Another aspect of the present invention relates to a process for recycling the coated article to obtain a recycled polypropylene and to the use of said recycled polypropylene.

Abstract: The present invention is directed to a multilayer structure. More specifically, the present invention is directed to a polypropylene multilayer extrusion laminate structure which provides sufficient thermal resistance and mechanical properties, and which multilayer structure can be recycled. The present invention is further directed to a process for producing the multilayer structure by an extrusion lamination process.
