Abstract: A packaging wrapper consisting of a film intended to be closed by two twists on either side of an article to be packaged, characterized in that the film comprises, on the internal side in relation to the article to be packaged, a sealing coating placed along two transverse strips on either side of the article to be packaged and extending parallel to an axis passing through the two twists. The film may additionally comprise two lengthwise strips of sealing coating extending on either side of the strips of sealing coating extending on either side of the article to be packaged, perpendicularly to the said transverse strips in the regions of formation of the twists. These sealing coatings may be either cold-sealing coatings or heat-sealing coatings.
