A primary function of the leafâs waxy cuticle is to reduce water loss through the leaves, which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall.
The first plant designed for rolling aluminum foil was opened in 1910. Aluminum foil replaced tin foil, when the Dr. Lauber, Neher & Cie., Emmishofen aluminum foil rolling plant in Kreuzlingen, Switzerland, was opened by J.G. Neher & Sons.
To make matters worse, the aluminum. foil is crinkled so that the reflecting surface is not uniform, and on the dull side. the reflectance is not even specular, i.e. there is a range of angles of reflection for a. specified angle of incidence, and that range depends upon the angle of reflectance.
