There are two ways;
1) Plastics can be metalized on the surface by the process of vacuum metalizing, in which metal filaments are vaporized on to the plastic surface and the condensed in a vacuum chamber.
2) Sputtering, the metal is ionized in a vacuum chamber by an electrical discharge between two electrodes, a metallic cloud forms inside the chamber and fogs the plastic parts with a thin layer of metal .

What is the process of plastic dip coating?
Process of Plastic Dip Coating:1. Part CleaningParts to be coated should be chemically cleaned to remove contaminants . This results in superior primer adhesion as well as improved corrosion resistance. 2. Part PrimingIf adhesion to the part is desired, application of a primer is required on all sections were polymer coating will be applied. The primed part is flash dried and baked to set the primer and ready the part for the hot dipping operation. 3. Part DippingThe primed part, hot from the primer conversion bake, is immersed in the liquid plastic polymer. All hot parts of the product immersed in the liquid polymer will coat upon withdrawal from the bath with a layer of semi-fused plastic. The amount deposited will depend on the length of time the part was immersed, the metal temperature that the part was immersed at, and the general formulation of the plastic compound used. The higher the metal temperature, the longer the immersion time, and the greater the film thickness. 4. Fusion (Curing) plastic polymerThe part covered with the semi-fused polymer is baked to a temperature between 300°F and 350°F, depending upon the specific plastic compound formula. This completes the fusion of the coating, and adhesion to the product. 5. Cooling the Coated PartWhen the hot part coated with fused polymer comes out of the oven, it is very sensitive to surface marring. The part is cooled down in a tank of circulating cool water to a maximum of 120°F before handling. 6. Complete end productThe finished coated product is then removed from the conveyors and readied for packing and shipment.
What is Nonwoven Fabric?
Non-woven fabric is made from long fibers bonded together by mechanical, heat, chemical and solvent treatment. This may be made directly from separate molten plastic, fibers and plastic film.
What is a thin film capacitor?
If you know what a capacitor is then a TFC refers to the way the capacitor is made. Boundary layers are separated by thin insulated film to provide compact multi-use capacitors for applications such as cell phones, avioniics etc.
What is a capacitor made of?
A basic capacitor is made up of two conductors separated by an insulator, or dielectric. The dielectric can be made of paper, plastic, mica, ceramic, glass, a vacuum or nearly any other nonconductive material. Some capacitors are called electrolytics, meaning that their dielectric is made up of a thin layer of oxide formed on a aluminum or tantalum foil conductor.
What is a film canister made out of?
Metal or plastic.
Is plastic bag metal?
Due to the way atoms are arranged in thin film plastics (like those of a plastic bag) they are indeed classed as a metal.
What is fluid film?
Fluid film is a lanolin-based rust and corrosion protection product that can be applied to metal surfaces to prevent them from rusting and corroding. It forms a protective barrier that penetrates and prevents moisture from reaching the metal, keeping it in good condition. Fluid film is commonly used in automotive, industrial, and marine applications.
Is metal plastic?
Due to the way atoms are arranged in thin film plastics (like those of a plastic bag) they are indeed classed as a metal.
How do you tell if an auto windshield has metal in it?
It doesn't, it is made of glass and plastic film to it from coming apart.
What is a film container?
Back in the days before digital camera technology, images were recorded on film. Film was stored in metal or plastic canisters. These canisters were called film containers.
How do you remove the plastic film from a new metal garage door?
Heptane is very helpful in removing the plastic film from a new metal garage door. If the adhesive resists organic solvents like toluene, MEK, xylene, etc., as well as citrus-based products, the adhesive may be acrylic-based and it might be attacked with household ammonia.
Why does a film badge have a plastic case and not a metal case?
The film has a dried silver emulsion on it which can be scratched and scraped if exposed to everyday handling. The plastic case is just there to hold the film in place and protect it from being scratched. The emulsion is on the reverse side, closest to your body, so nothing can touch it while it's in the case.
What kind of plastic is used in making a compact disc?
CDs are made from almost-pure polycarbonate plastic. A thin layer of aluminum or sometimes gold is applied to the surface to make it reflective. This in turn is protected by a lacquer film.
How is plastic film used in food packaging to ensure product freshness and safety?
Plastic film is used in food packaging to create a barrier that protects the food from outside elements like air, moisture, and bacteria. This helps to keep the food fresh for a longer period of time and reduces the risk of contamination. The film also provides a seal that prevents leaks and spills, ensuring the safety of the product during transportation and storage.
How is the breast positioned for a mammogram?
The technologist exposes one breast and places it on a plastic or metal film holder about the size of a placemat.
What makes plastic bags?
plastic film or sheet
