Metallized boPET film, 32 layers of ~14 μm thickness each. BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation.

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.
Multiple layers of protection are often used to protect from both mechanical damage and electrostatic damage. A protected device can be packaged inside a metalized PET film bag, inside a pink polyethylene bubble-wrap bag, which is finally packed inside a rigid black polyethylene box lined with pink poly foam.
Metal fiber sintered sheets are used for diesel and gasoline particulate filtration and crankcase ventilation filters. Heat-resistant textile materials are made from metal fibers for automotive glass bending processes. These metal fiber cloths protect the glass during the bending process with highly elevated temperatures and high pressures.
Polyethylene plastic sheet, 4 or 6 thou (0.10 or 0.15 mm), 0.03 US perm (1.7 SI perm). Advanced Polyethylene vapor retarders that pass the ASTM E 1745 standard tests ≤0.3 US perm (17 SI perm). Asphalt-coated kraft paper, often attached to one side of fiberglass batts, 0.40 US perm (22 SI perm). Metallized film
Some windows use laminate polyester film where at least one layer has been metalized using a process called sputtering. Sputtering occurs when a metal, most often aluminum, is vaporized and the polyester film is passed through it. This process can be adjusted to control the amount of metal that ultimately coats the surface of the film.
