More Information
Summary:A non-burning wrapper for use with smoking products comprises a base paper having a first side and a second side; said base paper being impregnated on both sides with calcium chloride and a reactive size for paper and carrying on one side atop of said impregnation a coating layer comprising calcium carbonate, potassium silicate and sodium carboxymethylcellulose. The non-burning wrapper is formed by treating a base paper with a solution consisting essentially of water, calcium chloride and a reactive size for paper; drying the thus treated paper; coating one side of the thus treated base paper with a solution consisting essentially of water, calcium carbonate, potassium silicate and sodium carboxymethycellulose; and drying the thus treated and coated paper to form a non-burning wrapper for use with smoking products.
