Cellulose casing for sausages, comprising at least three concentric layers
of regenerated cellulose, of which the two layers in contact with the
outside, that is, those with the greatest and smallest diameter
respectively are made of colorless, transparent viscose, and in which the
internal layer or layers are made of regenerated cellulose to which is
added other substances such as pigments, fumes, flavor extracts, spices
or plastic proteins.The object of the invention is a manufacturing method
for the cellulose casing obtained by extrusion of at least three
concentric layers of regenerated cellulose. Also object of the invention
is the circular viscose extrusion head used in manufacturing the
