Abstract

A description is given of a tubular food casing having a fiber layer on the inside and having two or more polymer layers. The polymer layers include a first continuous polymer layer (A), with which the inner fiber layer or nonwoven-web layer is coated on the side of the tubular casing facing away from the inside, and completely covers the layer, and at least one polymer layer (B), and a monoaxially or biaxially oriented film based on polyamide and/or copolyamide. At least two of the polymer layers are joined to one another directly by a layer of adhesive. The inner fiber layer may absorb colour, smoke, aroma and/or flavour substance(s), such as liquid smoke or caramel, store these substances and transfer them to a food located within the casino. The casing is suitable as artificial sausage casing, especially for cooked-filling and scalded-emulsion sausage.
