Non-burning outer wrapper for use with smoking products and method of producing same |
(57) 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.
