Application of Metallized Polyester Films

by Deepika Olive SEO Executive
Polyester film metallized with aluminum powder is called PET MET. PET is already known for its high strength and surface hardness and especially with regard to the diffusion density. These favorable properties can be improved through the use of aluminum powder. For packaging applications demanding very high barrier performance and good metal adhesion, metallized polyester films are developed. The product is protected throughout its targeted shelf time with the high barrier, whereas the high metal adhesion ensures high lamination bond strength.

Some countries have already replaced traditional aluminum-laminated packaging by metallized flexible plastic packaging. Substitution is more concentrated in some product categories such as tomato based products, powdered milk and coffee. And this migration trend from aluminum laminate to metallized films continues globally. In fact, it follows a quite strong trend: the substitution of rigid packages for flexible packaging, especially for pouches.

Types of Metallized Film

The polyethylene film manufacturers have a strong background and technical experience metallizing a wide variety of plastic substrates. Some of the common metallized plastic films produced by metallized polyester film manufacturers are listed below:

  • Metalized polyester film
  • Metalized polyethylene film
  • Metalized polyimide film
  • Metalized fluoropolymer film
  • Metalized DuPont  Tedlar film
  • Metalized ETFE film
  • Metalized PTFE film
  • Metalized PEEK film
  • Metalized BOPP film

Uses of metallized film-
All applications that require the preservation of flavor and freshness, uses metallized PET films as an ideal solution. For many applications in the packaging industry as well as for applications in the technical and industrial sectors, these metallized films are suitable.

  • With metallized PET film you can achieve a stronger mirror effect. This is also used when printing – for example, without a white primer, yellow color shimmer gold.
  • For snacks packaging, PET met foils are ideal. Thermoform able container covers such as yogurt cups or refill bags for cosmetic products are made out of metallized PET. Coffee and pet kibbles remain dry in those PET packaging and retain their full aroma and flavor for a long time.
  • In the particular case of acidic, alkaline or salt-containing foods, metallized PET films are a perfect substitute for aluminum foils, as a longer exposure or a large contact area of aluminum with those materials can release potentially harmful emission of aluminum into the edible content.
