The present invention relates to a multilayer, tube-shaped food film, particularly a sausage casing, wherein the food film is produced on a multilayer coextrusion blow film system by means of coextruded plastics fed to a blow head, and is stretched biaxially in a triple-bubble process. The food film comprises at least six layers. The at least six layers of the food film are thereby disposed as follows, from outside to inside: an outermost layer having a polyamide as a layer component, an innermost layer having a polyamide as a layer component, and a sequence of at least intermediate layers disposed therebetween, disposed as follows from outside to inside: a layer comprises a bonding agent as a layer component, a further layer comprises a polyolefin as a layer component, a further layer comprises a polyolefin as a layer component, and a further layer comprises a bonding agent as a layer component. The present invention further relates to a multilayer, flat food film produced from a multilayer, tube-shaped food film cut open for this purpose. |
