The present invention relates to a multilayer, tube-type food film, in particular sausage casing, wherein the food film is manufactured on a multilayer coextrusion film blow molding system by means of coextruded plastics supplied to a blowing head and stretched biaxially in the triple bubble process. The food film comprises at least six layers. The at least six layers of the food film are arranged from the outside to the inside, as follows: an outermost layer including a polyamide as a layer component, an innermost layer including a polyamide as a layer component, and an intermediately arranged succession of at least four intermediate layers being arranged from the outside to the inside, as follows: one layer includes an adhesion promoter as a layer component, another layer includes a polyolefin as a layer component, another layer includes a polyolefin as a layer component, and another layer includes an adhesion promoter as a layer component. The present invention further relates to a multilayer, planar food casing that is produced of a multilayer, tube-type food film cut open for this purpose.
