Reconstituted leaf (RL) sheet: a paper-like product constructed from recycled tobacco fines, tobacco stems and "class tobacco", which consists of tobacco particles less than 30 mesh in sizing (about 0.six mm) that happen to be gathered at any stage of tobacco processing:[eighty two] RL is created by extracting the soluble chemical compounds during the tobacco byproducts, processing the leftover tobacco fibers within the extraction into a paper, and afterwards reapplying the extracted elements in concentrated type onto the paper within a trend comparable to what is finished in paper sizing.
