<p>A thermoplastic multi-layer foil structure comprises a styrenic polymer layer and an olefinic polymer layer bonded by an intermediary polymer layer comprising at least one layer constituted by a bonding agent. In this multi-layer structure, at least one layer containing scrap produced from said multi-layer foil structure is included in the latter, said scrap-containing layer including a mixture of said scrap with a convenient proportion of a graft copolymer of a styrenic monomer on a polyolefinic substrate.</p> |
