A tube-shaped food wrapper is disclosed, particularly a sausage wrapper, comprising at least two layers. The inner layer facing the food is provided with a matrix made of an organic, thermoplastic polymer material and a powdered organic filler which is embedded therein and contains a food additive that can be transferred to the filling material. The organic filler preferably consists of a carrageenan powder while the food additive preferably consists of a liquid smoke. At least one additional layer has barrier properties, i.e. is provided with a reduced permeability to water vapor and/or atmospheric oxygen. Layers based on polyolefin or polyamide are particularly suitable for the addtional layer(s).
