Abstract

A paper for fiber reinforcement in a base layer of a cellulose-based packaging film, in particular a tubular artificial sausage casing, or for tea-bags, wherein the paper includes alginic acid and/or an alginate which is substantially insoluble in water. A process for producing the paper which includes adding a water-soluble alginate to an aqueous suspension of cellulose fibers and precipitating the water-soluble alginate so as to form a substantially water-insoluble alginic acid or alginate.
