Elle se caractérise en ce que ladite feuille présente dans son épaisseur des pores ou fines perforations répartis sur toute sa surface, ladite feuille ayant une "voluminosité" ou "main" exprimée en centimètres cube par gramme, supérieure à 2,5, la rendant apte à autoriser le passage de l'air sous l'effet d'une aspiration produite en dessous de sa face inférieure.
