Abstract: An easy opening film package for wrapping cubic or rectangular shaped articles is prepared from a film having a printed portion containing ink and a compatible thermoplastic resin on one surface of the film. The film is wrapped around the article and heat sealed in the area of overlap of the film ends. The printed portion extends to the ends of the film and across the film over a width substantially coextensive with the width of the face of the article on which the seal is to be located.
