Metallised films (or metallized films) are polymer films coated with a thin layer of metal, usually aluminium. They offer the glossy metallic appearance of an aluminium foil at a reduced weight and cost. Metallised films are widely used for decorative purposes and food packaging, and also for specialty applications including insulation and ...
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.

The self-healing capability of metallized films is used multiple times during the manufacturing process of metallized film capacitors. Typically, after slitting the metallized film to the desired width, any resulting defects can be burned out (healed) by applying a suitable voltage before winding.
Aluminising vacuum chamber at Mont Mégantic Observatory used for re-coating telescope mirrors. [1]Vacuum deposition is a group of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface.
A thin film is a layer of materials ranging from fractions of a nanometer to several micrometers in thickness. [1] The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Metallic filaments can be coated with transparent films to minimize tarnishing. Many methods exist to manufacture metallic fibers, and each comes with its own benefits and limitations. The most common methods include shaving from a larger stock, [ 3 ] casting directly from molten metal, and growing around a seed.
Physical vapor deposition (PVD), sometimes called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including metals, ceramics, glass, and polymers. PVD is characterized by a process in which the material transitions from a condensed phase to a ...
