Claims36
A cellulosic tubular food casing containing an olefinic oxide polymer uniformly dispersed through the tube wall in admixture with the cellulose and in sufficient quantity so that the olefinic oxide polymer-to-cellulose weight ratio is at least about 1:200, and wherein said olefinic oxide polymer has an average molecular weight of at least about 70,000.
A nonreinforced tubular cellulosic food casing in shirred form and without a polyhydric alcohol softening agent but containing poly(ethylene oxide) of greater than about 70,000 molecular weight and being uniformly dispersed through the tube wall in admixture with the cellulose and in sufficient quantity so that the poly(ethylene oxide)-to-cellulosic weight ratio is between about 0.5:95 and 5:95.
