| 摘要 |
<p>The invention relates to a process for producing a container (26), made of a thermoplastic material, the process comprising a final step (E2) of forming the container (26) by blow moulding or stretch-blow moulding during which at least one portion (14) of the body (18) of the preform (10) undergoes a more rapid stretching than the rest of the body (18), characterized in that it comprises: - an initial step (E0) of manufacturing the preform (10) during which the body (18) is made using a first thermoplastic material, each portion (14) to be stretched more rapidly comprising a second layer (32) of a second thermoplastic material that has a higher coefficient for absorption of the heating radiation than that of the first material; - an intermediate step (E1) of heating via uniform exposure of the body (18) of the preform to the electromagnetic heating radiation.</p> |
