Metallised films are used as a susceptor for cooking in microwave ovens. [5] An example is a microwave popcorn bag. Many food items are also packaged using metallised films for appearance only, as these produce a package with greater sparkle when compared to competing products that use printed paper or polymer films.
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.

Plastic film capacitors potted in rectangular casings, or dipped in epoxy lacquer coating (red color) Film capacitors, plastic film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes.
Surface treatment systems are available for virtually any surface format including dimensional objects, sheets and roll goods that are handled in a web format. Corona treatment is a widely used surface treatment method in the plastic film, extrusion, and converting industries. [1]
Plastic films are typically formed into rolls by roll slitting. Often additional coating or printing operations are also used. Films can be modified by physical vapor deposition to make metallised films. Films can be subjected to corona treatment or plasma processing; films can have release agents applied as needed.
Today's metal fiber industry mainly offers fibers in stainless steel, nickel, titanium, copper and aluminium for various applications. [2] 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.
