A film-forming hydrocolloid composition comprising kappa carrageenan, iota carrageenan, a bulking agent, plasticizer and water is described. The ratio of bulking agent to total carrageenan is from about 1:1 to 20:1. Kappa carrageenan is present in an amount of less than or equal to 50% by weight of total carrageenan present. To form the composition, all dry materials are mixed and added to a heated mixture of all liquid materials. The final mixture is heated until a composition free of particulate materials is formed. The formed composition can be cast or extruded into ribbons, films, sheets, tubes or the like, for encapsulating wet or dry materials including medicinal dosage forms, nutritional supplements, cosmetics, bath oils and gels, and paint balls.

L'invention concerne une composition hydrocolloïde filmogène contenant du kappa carraghénane, du iota carraghénane, un agent gonflant, un plastifiant et de l'eau. Le rapport entre l'agent gonflant et la quantité totale de carraghénane est compris sensiblement entre 1:1 et 20:1. Le kappa carraghénane est présent dans une quantité inférieure ou égale à 50 % en poids de la quantité totale de carraghénane présent. Cette composition est formée par mélange de toutes les substances sèches et par ajout du mélange obtenu à un mélange de toutes les substances liquides, ce deuxième mélange étant chauffé. Le mélange final est chauffé jusqu'à obtention d'une composition exempte de matières particulaires. La composition formée peut être coulée ou extrudée sous forme de rubans, films, feuilles, tubes ou similaires destinés à être utilisés pour encapsuler des matières humides ou sèches, notamment des formes posologiques, des suppléments nutritionnels, des produits cosmétiques, des huiles et gels de bain et des balles de peinture.
