The Creative Process of Metallized PET Film

The Creative Process of Metallized PET Film

Aug 18,2022
Metallized PET films are high-quality polymer films with a thin layer of metal, usually aluminum, on top. These films have a glossy metallic appearance similar to aluminum foil but are lighter and less expensive. Metallized PET films are widely used in food packaging and decorative applications, but also in specialty applications such as electronics and insulation.

Metallized PET films are best for flexible holograms and laminations. Although, the product's most well-known applications include its use in food packaging. Metal thin films are produced by a micro-slitting process to ensure uniform coating and consistent weight.


Metallization is achieved using a physical vapor deposition process. Aluminum is the predominant metal for deposition; however, other metals such as chromium or nickel are also used. Metals are heated and dissolved under a vacuum. This focuses on the cold polymer film, which unfolds next to the source of metal vapor. This coating will not fade over time.

These films are essentially impermeable to oxygen and moisture. However, when packages made with these foils are subjected to the repetitive handling and manipulation that often occurs in cartoonization, manufacturing, consumer handling, and shelf storage in retail environments, they can develop pinholes and develop permeability.

These films have a shiny silver finish like aluminum foil. The provided coating also reduces the exposure of the film to oxygen, light, and water. Compared to aluminum foil, the film is characterized by high toughness, thermal insulation capacity, and low density at a lower cost. This provides many benefits for metalized PET films compared to foil laminates and foils. It has been suggested that metalized films could be an alternative to aluminum foil laminates, but current films still cannot match the barrier properties of aluminum foils.

The above briefly understand the creative process of metalized PET film. If you want to buy metalized PET film, please contact us.

Which to choose Aluminum foil coated PE or Metalized pet film coated PE ?

It depends on what product to be made in final procedure. Aluminum foil coated pe is with at least 97% reflectivity, it can be bonded to EPE foam but also most of time for laminated with bubble. Metalized pet film coated PE with lower reflectivity ,but it is with strong surface.

I am a insulated liner/bag manufacturer,what product do you suggest?

There maybe bubble lamination machines and heating pressure lamination machines in your factory, we suggest Aluminum foil 7mic+PE20mic, and Metalized PET film12mic+PE15mic.

If i would like to get a quote ,what information shall i need to know first?

You are request to telling application, material structure,thickness and roll width and quantity.

What is the MOQ and how is packaging?

MOQ is 1000kgs for each product, packaging depends on roll size, common width is 1200mm and 1500mm, length are 4000m to 5000m per roll. Rolls can be vertically packed on pallet also accept to do horizontal suspending packaging.

Is this product by wet lamination or by dry lamination?

Both wet lamination line(extrusion coating) and dry lamination line(glue coating) are equiped in our Pengyuan group.
