Abstract: The present invention relates to a method for obtaining artificial casing for filling foodstuffs and artificial casing obtained by means of said method, which comprises extruding gel through an output slot having a closed, polygonal and non-circular geometric configuration, obtaining a tubular film with a circular cross-section due to the effect of pressure exerted by a fluid that is injected into said hollow tubular film, such that the artificial casing obtained has a high dilation capacity in its cross-section, while at the same time maintaining the same longitudinal traction values as a casing obtained using a circular slot of the same caliber.
