Antimicrobial film based on biopolymers, in particular cellulose and/or protein, or uncoated or coated textile material, and also an antimicrobial sponge or an antimicrobial sponge cloth based on regenerated or precipitated cellulose are provided. The film, the sponge or the sponge cloth is impregnated or coated with at least one &#x3b1;-amino acid ester, the &#x3b1;-amino group of which is acylated with a fatty acid, or the corresponding hydrochloride, and the &#x3b1;-amino acid ester is bound covalently, optionally also ionically, to the film, the sponge or the sponge cloth. The acylated &#x3b1;-amino acid ester is preferably N-lauroyl-L-arginine ethyl ester monohydrochloride (LAECl), N-lauroyl-L-arginine methyl ester monohydrochloride (LAMCl) or N-lauroyl-L-lysine ethyl ester hydrochloride (LLECl). The film is preferably in the form of a flexible tube and is provided as casing for foods, especially sausage products.

The invention relates to a wet-fast nonwoven, preferably a fiber paper, which comprises fibers from a cellulose-containing material and fibers from a thermoplastic material welded firmly together at their points of intersection. The fibers from the cellulose-containing material are preferably hemp fibers while the fibers from the thermoplastic material are preferably fibers from polypropylene, polyester or polyamide. The fibers are interlinked under the action of pressure and/or heat, especially using a pair of heated calender rolls. The nonwoven or the fiber paper is especially used to reinforce food casings based on regenerated cellulose, especially in artificial cellulose hydrate-based sausage skins.
