Abstract

The present invention provides a recyclable multi-layered coextruded bi-axially oriented thermoplastic food casing characterized by a high polyolefin content, two skin layers essentially of the same polyolefin type, a non-skin layer with a component, having a density greater than 1,00 g / cm³, an overall density of less than 1,00 g / cm³ and a ratio of stiffness in transversal direction to stiffness in machine direction of more than 1, where the high stiffness is obtained without radiation / crosslinking. The casing yields wrinkle-free sausages.
