Abstract
A composition for coating a cellulosic packaging material that includes water, starch at a concentration of about 10% to about 17% by weight, gelatin at a concentration of about 10% to about 12% by weight, glycerol at a concentration of about 5% to about 11% by weight, one or more protein ingredients at a concentration of about 5% to about 10% by weight, and one or more porophors at a concentration of about 3% to about 5.5% by weight. The present invention also relates to a method of preparing the composition for coating cellulosic packaging material.
Claims12
A composition for a coating for a cellulosic packaging material comprising water, starch at a concentration of about 2% to about 25% by weight, gelatin material at a concentration of about 8% to about 15% by weight, glycerol at a concentration of about 4% to about 15% by weight, one or more protein ingredients to make the coating at a concentration of about 5% to about 10% by weight in addition to the gelatin material, wherein the protein ingredients are selected from the group consisting of egg albumin, foamable albumin, sodium caseinate, casein, milk protein, soy protein, zein, gluten, and mixtures thereof, one or more porophors at a concentration of about 2% to about 10% by weight, wherein the one or more porophors are selected from the group consisting of bicarbonates of alkali metals, bicarbonates of ammonium, mixtures of said bicarbonates, and azodicarbonamide, all combined in a foamed coating on top of a paper or cardboard packaging material.
