CURVED TUBULAR PACKAGING CASINGS, ESPECIALLY SAUSAGE CASINGS

摘要

This casing made of unreinforced cellulose has a cross-section with differing wall thicknesses. The section having the minimum wall thickness is opposite the section having maximum wall thickness and is in the section having the larger, outer radius of curvature. The thickness of the section having the maximum wall thickness is in the range of 50 to 160 micrometres, that of the minimum wall thickness is in the range of 10 to 50 micrometres. The maximum of the wall thickness is greater than the minimum of the wall thickness by 50 to 800%. On account of the relationships of its wall thicknesses, the casing shows improved physical properties which are particularly of importance for its use as a synthetic casing for sausages.
