The shielding effectiveness of aluminium foil depends upon the type of incident field (electric, magnetic, or plane wave), the thickness of the foil, and the frequency (which determines the skin depth). Shielding effectiveness is usually broken down into a reflection loss (the energy bounces off the shield rather than penetrates it) and an absorption loss (the energy is dissipated within the shield).
Although aluminium is non-magnetic, it is a good conductor, so even a thin sheet reflects almost all of an incident electric wave. At frequencies more than 100 MHz, the transmitted electric field is attenuated by more than 80 decibels (dB) (less than 10−8 = 0.00000001 of the power gets through)  -- however actual energy absorption is minimal: the remaining high-frequency rf energy is almost perfectly reflected from uniform flat aluminium surface, and thus, reflected signal may continue to propagate internally, and if holes or passages of suitable geometry exist in the shield, signal propagation may continue out through those, the aluminium being good material for implementation of a microwave-frequency waveguide.
1、suspend the roll in seaworthy wooden cases,with polyfoam to protect the edges of the roll from mechanical damage.
