Aluminium ffoyle est genus Aluminii materialis volubilis. aluminium foil is mainly for thickness. In industria, aluminium producta crassitudine minus quam 0.2mm vocari solent aluminium foil. Simul, secundum crassitudine, aluminium ffoyle in duplici nulla ffoyle dividi potest, una nulla ffoyle ac densissima ffoyle, sic scis quomodo discerneres inter imam nullius claui et duplicem nulla claua?

This is easy to distinguish, just look at the thickness, single zero foil: foil with a thickness of 0.01mm and less than 0.1mm, double zero foil: the so-called double zero foil means that there are two zeros after the decimal point when the thickness is measured in mm foil, usually aluminum foil less than .0075 mm in thickness.
