THE INVENTION RELATES TO A COMPONENT COMPRISING AN INSERT PART AND PLASTICS JACKETING COMPOSED OF AT LEAST TWO PLASTICS COMPONENTS, WHERE THE INSERT PART IS ENCLOSED BY A FIRST PLASTICS COMPONENT A AND THERE IS A SECOND PLASTICS COMPONENT B ENCLOSING THE FIRST PLASTICS COMPONENT A, WHERE THE FIRST PLASTICS COMPONENT A IS COMPOSED OF: A1: FROM 5 TO 80% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF COMPONENTS A1 AND A2, OF AT LEAST ONE POLYESTER BASED ON ALIPHATIC AND AROMATIC DICARBOXYLIC ACIDS AND ON ALIPHATIC DIHYDROXY COMPOUNDS; A2: FROM 20 TO 95% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF COMPONENTS A1 AND A2, OF AT LEAST ONE HOMO- OR COPOLYESTER SELECTED FROM THE GROUP CONSISTING OF POLYLACTIDE (PLA), POLYCAPROLACTONE, POLYHYDROXYALKANOATES, AND POLYESTER DERIVED FROM ALIPHATIC DICARBOXYLIC ACIDS AND FROM ALIPHATIC DIOLS; A3: FROM 0.05 TO 15% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF COMPONENTS A1 AND A2, A) OF A COPOLYMER WHICH CONTAINS EPOXY GROUPS AND WHICH IS BASED ON STYRENE, ON ACRYLATE, AND/OR ON METHACRYLATE, B) OF A BISPHENOL A EPOXIDE, OR C) OF A FATTY ACID AMIDE OR FATTY ACID ESTER, OR NATURAL OIL CONTAINING EPOXY GROUPS; AND THE SECOND PLASTICS COMPONENT B IS COMPOSED OF B1: FROM 50 TO 100% BY WEIGHT OF AT LEAST ONE SEMICRYSTALLINE, THE THERMOPLASTIC POLYESTER BASED ON AROMATIC DICARBOXYLIC ACIDS AND ON ALIPHATIC OR AROMATIC DIHYDROXY COMPOUNDS AND B2: FROM 0 TO 50% BY WEIGHT OF AT LEAST ONE THERMOPLASTIC STYRENE (CO) POLYMER, IN EACH CASE BASED ON THE POLYMER CONTENT OF THE SECOND PLASTICS COMPONENT B.
