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. [1]
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.

This process involves heating the metal until it vaporizes then depositing it at a high pressure onto the polyester film . [4] This process produces thinner, more flexible, more durable, and more comfortable fibers. [9] Metal fiber may also be shaved from wire (steel wool), shaven from foil, or bundle drawn to form larger diameter wire. [3]
The initial product range was limited to metallized and non-metallized Dyed Films. The primary use of window tinting was once for privacy and protection against harmful ultraviolet rays. Today, the industry has evolved to provide higher heat reduction films through the coating of metals and ceramics on the polyester films.
