摘要： An injection moulding process for making a completely recyclable, multilayered article which contains: i) a rigid layer formed of a thermoplastic polymer and ii) a foamed skin layer formed of a thermoplastic polymer compatible with the material of the rigid layer, by injection moulding of the rigid layer into a mould composed of two sides, lifting one side of the mould, or change one side of the mould to obtain a small gap of between 3 to 4 mm between the rigid layer and the side of the mould lifted or changed and injecting the foamed skin layer into the gap formed in step b).
