Patent ID: 7837818

Claim:
A method of manufacturing a wrapper for packaging one or more articles, the wrapper including a sleeve of heat-shrink plastics material for shrinking onto the article(s) for packaging, the sleeve being made from a film, wherein the wall of the sleeve is embossed at least in part with a predetermined pattern so that the pattern appears in relief on the outside face and/or the inside face of the sleeve and remains after the sleeve has been shrunk onto the article(s) to be packaged, the method comprising steps of: embossing the film while flat with the pattern; subsequently folding the embossed film so that the pattern appears in relief on a convex outside face and/or on a concave inside face of the film; and uniting end zones of the film to form the sleeve, wherein the film is coated, in a location of the pattern that is to be embossed or that has already been embossed, on the face of the film that corresponds to the recessed side of the embossing and/or on the opposite face, with a technical agent that retains the relief during shrinkage of the wall of the film.
