Abstract

Abstract The term ''''food casing,'''' as employed throughout this application and in the appended claims, is intended to include, but not be restrictive of, those tubular food casings fabricated from such materials as collagen, cellulose, regenerated cellulose, cellulose having fibers embedded therein, polyvinyl chloride, polypropylene, polyethylene, polyvinylidene chloride, and the like. These food casings are also known by those skilled in the art as ''''sausage casings'''' and are generally employed as containers or molds into which is stuffed or encased a food item, such as raw meat emulsions, meat chunks, discrete meat cuts and the like. These encased food items can then be frozen or, if desired, processed, as by cooking and curing, and items such as salami and bologna sausages, spiced meat loaves, ham loaves, hams, and the like can be obtained.
