Abstract:
1. Method for producing at least one raised area on a plastic container, comprising: obtaining an IML label produced from a film of between 30 and 50 μm thick; printing an area on at least one face of the filmwith an ink or varnish; arranging the film in a cavity of a mould so that the printed area is not in contact with the mould; in the cavity equipped with the film, injecting plastics material and simultaneously injecting an expansion agent as a supercritical fluid such that a mixture of the plastics material and the fluid is transformed into a solution with a complete single phase, and varying temperature and pressure to obtain a micro-cellular internal structure in which said printed area does not adhere to melted plastics material, the expansion agent being trapped between the label and the plastics material, creating a raised effect in the printed area.
