Homogenized Tobacco Leaf (HTL) is a paper-like material produced from finely ground tobacco. The inner and outer envelopes of machine-made cigars (termed binder and wrapper, respectively) often consist of HTL, as it displays greater mechanical resistance and uniformity than whole tobacco leaves.
On the following report we measured the particle size of tobacco powders destined for HTL manufacturing of cigar binder and cigar wrapper using a PSA. Tobacco particles proved fragile and measurement parameters had to be adjusted tightly to limit mechanical stress. Measurements were performed both in dry and in liquid mode and showed excellent repeatability. The tobacco powder destined for wrapper manufacturing displayed slightly smaller particle sizes and a more homogeneous distribution than the binder, indicating that the resulting wrapper HTL could be of thinner and smoother quality than the binder HTL.
