Title
(EN) METHODS AND COMPOSITIONS FOR MAGNETIZABLE PLASTICS
(FR) PROCÉDÉS ET COMPOSITIONS POUR MATIÈRES PLASTIQUES MAGNÉTISABLES
Abstract
(EN) Provided herein are methods and compositions comprising a non-toxic ferromagnetic ink composition. Also provided herein are plastic objects containing a surface coating of a food-safe ferromagnetic ink composition. The coating imparts functionality to a plastic object such that the object is capable of being mechanically separated from waste stream using a commercial magnetic separator. The food-safe ink composition, which can be printed using high-speed flexographic, intaglio, offset printing or pad printing, combined with heat transfer printing or hot foil stamping consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties. The surface of the plastic object described can consist of geometric designs which increase printable surface area without significant changes in dimensions of the said object.
(FR) L'invention concerne des procédés et des compositions comprenant une composition d'encre ferromagnétique non toxique. L'invention concerne également des objets en plastique contenant un revêtement de surface d'une composition d'encre ferromagnétique alimentaire. Le revêtement confère une fonctionnalité à un objet en plastique de telle sorte que l'objet peut être mécaniquement séparé du flux de déchets à l'aide d'un séparateur magnétique commercial. La composition d'encre alimentaire, qui peut être imprimée à l'aide d'impression flexographique à grande vitesse, en creux, en impression offset ou en tampographie, combinée à l'impression par transfert de chaleur ou à l'estampage à chaud, est constituée d'un pigment pouvant être ingéré magnétiquement sensible capable de rendre le modèle imprimé avec des propriétés magnétiquement actives. La surface de l'objet en plastique décrit peut être constituée de dessins géométriques qui augmentent la surface imprimable sans modification significative des dimensions dudit objet.
