Abstract (en)
The paper or cardboard (1) has an undercoat (2) in a coating mass composed of water, amorphous silicon oxide, aluminium oxide, PVA and a copolymer of styrene,butadiene and acrylonitrile. Alternatively it is composed of water, silicic acid or precipitated silicic acid, PVA and a copolymer of styrene, butadiene and acrylonitrile. The covering layer (3) is a coated mass of water with a copolymer of styrene and butadiene modified with carnauba and paraffin wax, an ethylene/methacrylic acid dispersion and polyvinyl acetate. It can use carboxylated styrene-butadiene or styrene-acrylate copolymer dispersion.
Abstract (de)
Die Erfindung betrifft ein Papier oder Karton 1 mit einer aus Vorstrich 2 und Deckstrich 3 bestehenden Beschichtung zur Schaffung einer Aroma- und Dampfsperre. Der Vorstrich 2 in der Streichmasse besteht aus den Komponenten Wasser, amorphes Siliciumdioxid, Aluminiumoxid, Polyvinylalkohol und einem Copolymer von Styrol-Butadien und Acrylnitril oder aus den Komponenten Wasser, Kieselsäure, Polyvinylalkolhol oder einem Copolymer von Styrol-Butadien und Acrylnitril. Im Zusammenwirken mit einem entsprechenden Deckstrich 3 wird mit einer geringen Schichtdicke eine optimale Barrierewirkung erzielt, wobei darüber hinaus sehr gute Recyclingfähigkeiten gegeben sind. <IMAGE>
