Multi-layered plastic casing having a porous food contact side, suitable for transferring food additives

Abstract

A coextruded, multi-layered, water vapor-impermeable, tubular, and seamless food casing having at least three layers is provided. The layers include at least one porous layer having a porous food contact side suitable for transferring food additives having a porous food contact side, at least one carrier layer based on at least one aliphatic and/or partially aromatic (co-)polyamide, and at least one water vapor-impermeable layer. At least one adhesive layer including an adhesion-promoting component is arranged between the adjoining layers or an adhesion-promoting component is contained in one or more of the water vapor-impermeable layer(s). At least one porous layer includes an aliphatic (co-)polyamide and a hydrophilic (co-)polymer having a mean molar mass Mw of at least 8000 Da. A method for producing the food casing is provided. The food casing is used as an artificial sausage casing, especially, for cooked or boiled sausage.
