1. An aerosol generating substrate element comprising:
a cylindrical aerosol generating substrate comprising from about 10% to about 30% glycerine by weight;
a first paper wrapper comprises opposing edges that abut each other to circumscribe the aerosol generating substrate and form a first seam line;
a second paper wrapper comprises opposing edges that abut each other to circumscribe the first paper wrapper and form a second seam line; and
the first seam line is offset from the second seam line and the first paper wrapper and the second paper wrapper do not extend beyond the aerosol generating substrate.
