Abstract:
1. A cold seal adhesive material, the adhesive comprising: latex emulsion comprising between 15 to 65 percent of the adhesive by weight; and ammoniated water, wherein the adhesive viscosity is between 10 and 450 centipoise at 25 degrees Celsius, the density is between 8.0 and 9.0 pounds per gallon at 25 degrees Celsius, and the basicity is between 9.5 and 12 pH, wherein the adhesive is adapted to be applied as a film on a substrate by a modified flexographic printing press process at a rate of at least 1,750 square feet per minute of the substrate without agglomeration of the adhesive, wherein the film has a film weight between 0.01 and 0.04 grams per square inch of the substrate, and wherein further, when applied and dried on the substrate, the adhesive must be compressed with a sealing pressure between 50 and 1,000 pounds per square inch to produce a cohesive bond between two or more adhesive regions.
