Abstract: The present invention relates to a multicomponent plastic product comprising at least two different thermoplastic materials, wherein a first thermoplastic material comprises a first thermoplastic polymer, and a second thermoplastic material comprises at least a second thermoplastic polymer and at least one degrading enzyme able to degrade the first thermoplastic polymer. The second thermoplastic material has a transformation temperature lower than the transformation temperature of the first thermoplastic material, and the first and second plastic materials are at least partially adjacent in the multicomponent product.
