  • Films containing foamable inks or coatings and process for separating similar density materials
    Patent number: 9555419
    Abstract: The present invention is directed to films that are deposited with foamable inks or coatings. One purpose is to facilitate their separation for recycling purposes. The films are particularly useful as packaging labels. The inks/coatings are designed so that foaming is activated when the film is in the hot-wash stage of a typical recycle process. This provides added buoyancy to the film allowing it to float to the surface and be removed, thereby significantly improving the efficiency of the recycle process. A feature of the invention is that, prior to this hot wash, the inks/coatings remain substantially unfoamed and thereby do not negatively affect the aesthetics of labeled package. The foamable inks/coatings can be used with any type of film.
