Abstract:
The invention relates to a biaxially drawn multilayer tubular film consisting of at least five layers, in which the external and two other layers contain aliphatic (co)-polyamide in a quantity equal to or greater than 50% by weight and are differently assembled. The inventive tubular film is produced by coextrusion and, thereby is seamless. Said tubular film can be used in the form of food product packagings, in particular as synthetic sausage casing.
