ABSTRACT:
A wrapper particularly useful for smoking articles of the type containing a burn fuel element and ceramic jacket. The wrapper includes an inner layer for surrounding the burn fuel element and jacket and an outer layer with the combination imparting controlled throttling properties. The inner layer may be a conventional cigarette wrapper material of cellulosic construction and having biased burned properties. The outer layer surrounds the inner sheet and preferably comprises cellulose fibers, titanium dioxide, attapulgite clay, high temperature resistant microfibers, and a burn enhancer. The outer wrapper also maintains permeability and pressure drop properties at temperatures in excess of 400.degree. C. while the inner wrapper burns out resulting in generally infinite permeability after burning. The combination in use possesses sufficient mechanical strength to support the assembly of components in specialty smoking articles and as burned properties that produce an ash appearance similar to conventional cigarette ash and has a high degree of ash integrity.
