Abstract
Przedmiotem zgłoszenia jest kompozycja na powlokę barierową, zwłaszcza na papier opakowaniowy do żywności, składa się z 64,5% wag. 78% wodnej zawiesiny węglanu wapnia, 15,7% wag. lateksu, 12,2% wag. skrobi, 3,6% wag. γ-cyklodekstry, 2% wag. glicerolu oraz 2% wag. wody. Zgłoszenie obejmuje też sposób wytwarzania kompozycji na powłokę barierową, zwłaszcza na papier opakowaniowy do żywności, który prowadzi się tak, że w urządzeniu zaopatrzonym w mieszadło umieszcza się 64,5% wag. 78% wodnej zawiesiny węglanu wapnia i dodaje się 15,7% wag. lateksu. Przy ciągłym mieszaniu z prędkością co najwyżej 40 obrotów/minutę mieszaninę podgrzewa się do temperatury 95°C przy ciśnieniu atmosferycznym uzyskując roztwór, który chłodzi się do temperatury 90°C. Przy ciągłym mieszaniu dodaje się 12,2% wag. skrobi i podczas jej kleikowania utrzymuje się mieszanie do czasu utworzenia roztworu koloidalnego. Po czasie co najmniej 5 minut po utworzeniu roztworu koloidalnego, kontynuując mieszanie dodaje się 3,6% wag. γ-cyklodekstryny, a następnie 2,0% wag. glicerolu i 2,0% wag. wody. Po upływie co najmniej 120 minut mieszaninę schładza się do temperatury powlekania papieru. Przedmiotem zgłoszenia jest też papier opakowaniowy do żywności co najmniej dwuwarstwowy, w którym na warstwie papierowej jest warstwa powłoki barierowej z wysuszonej kompozycji na powłokę barierową, a także sposób powlekania papieru opakowaniowego do żywności kompozycją na powłokę barierową, który prowadzi się tak, że kompozycję na powłokę barierową podaje się na maszynę powlekającą wyposażoną w grzany mieszalnik oraz podgrzewane wałki powlekające, którymi nanosi się kompozycję na powłokę barierową na papier. Powleczony papier umieszcza się w tunelu suszącym i suszy się.The subject of the application is a composition for a barrier coating, in particular for food packaging paper, consisting of 64.5% by weight. 78% aqueous calcium carbonate suspension, 15.7% by weight. latex, 12.2% by weight starch, 3.6% wt. γ-cyclodexters, 2% wt. glycerol and 2% by weight water. The application also includes a method for preparing a composition for a barrier coating, especially for food packaging paper, which is carried out in such a way that 64.5% by weight of 78% of an aqueous suspension of calcium carbonate and 15.7% by weight are added. latex. With continuous stirring at a speed of at most 40 rpm, the mixture is heated to 95°C at atmospheric pressure to obtain a solution which is cooled to 90°C. With constant stirring, 12.2% by weight is added. starch and stirring is maintained during its gelatinization until a colloidal solution is formed. At least 5 minutes after the formation of the colloidal solution, 3.6% by weight is added while stirring. γ-cyclodextrins followed by 2.0 wt.%. glycerol and 2.0% by weight water. After at least 120 minutes, the mixture is cooled to the paper coating temperature. The subject of the application is also at least two-layer food packaging paper, in which on the paper layer there is a barrier coating layer of the dried barrier coating composition, as well as a method of coating food packaging paper with a barrier coating composition, which is carried out in such a way that the coating composition the barrier coating is fed to a coating machine equipped with a heated mixer and heated coating rollers, which apply the composition to the barrier coating on the paper. The coated paper is placed in a drying tunnel and dried.
