To obtain a composite material having good processability and printability by laminating a specific polyolefin-containing layer, an intermediate layer comprising polyolefin having a specific reactive group and a lower layer containing a specific ethylene/vinyl alcohol copolymer.
The decorative upper layer 1 of a composite material comprises predetermined polyolefin with an MFI value (230°C/2.16 kg) of 3-9 g/10 min containing 0.1-3 pts.wt. of a dye or color pigment, 0.01-5 pts.wt. of a stabilizer and 0-50 pts.wt. of a filler and/or a processing aid or an additive per 100 pts.wt. of polymer and has a thickness of 60-600 μm and the adhesion accelerating intermediate layer 2 adjacent to the upper layer comprises a propylene graft polymer having a reactive group with an MFI value of 3-9 g/100 min or functionalized and contains 10 wt.% of polyethylene with regard to the polymer and has a thickness of 0.3-100 μm. A lower layer 3 comprises an ethylene/vinyl alcohol copolymer with an MFI value of 3-9 g/10 min and containing 25-40 wt.% of ethylene with regard to the copolymer and has a thickness of 0.3-100 μm.
