<p>The method for making a graphic representation on objects made of a polyolefin polymer, consists of printing a graphic representation on a face of a first film made of a stretched polyolefin polymer, associating the first film with a second film having a lower melting point than that of the first film, in order to obtain a membrane formed by the associated first and second films containing the graphic representation between them, transferring the membrane inside an injection mold and injecting a polyolefin polymer in the mold for forming the object, obtaining at least a partial melting of the second film so that the membrane forms one body with said object.</p> |
