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), that is less than 10 −8 = 0.00000001 of the power gets through.

Metallised films have a reflective silvery surface similar to aluminium foil and are highly flammable. The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil.
1. Tomatoes. The high acidity in tomatoes can react strongly with aluminum, causing tiny bits of metal to leach into the food. While this can impart that gross metallic taste, the bigger issue is ...
