PET MET is a Polyester film metallized with aluminum powder. PET is already known for its high strength and surface hardness and especially with regard to the diffusion density; the favorable properties can be improved through the use of aluminum powder. Metallized polyester film developed for packaging applications demanding very high barrier performance and good metal adhesion. 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.
Process-
Metallized polyester film manufacturers produce these films using physical vapor deposition process. Aluminum is the main metal for deposition; however other metals like chromium or nickel are also used. The metals which are heated are then dissolved under vacuum which concentrates on cold polymer films and these unwind next to metal vapor source. Such coatings do not fade over time.
Advantages-
From a simplified production process to logistics optimization the benefits include-

Advantages-
From a simplified production process to logistics optimization the benefits include-
- reduction of packaging weight
- possibility of better filling the space during transport and storage
- Flexibility of formats and opening / reclosing systems, etc.
- flexible packaging and its production process is totally safe to the product
- Metallized polyester films provide excellent barrier to moisture and oxygen
For consumers-
Flexible packaging tends to be more economical than rigid, with the same, and sometimes even better, barrier properties. This is an attribute that is being watched with great interest by several market sectors, especially by the pharmaceutical and food industries.

For Environment-
- These pouches have a smaller carbon footprint
- The CO2 emission is lower during the production process of a pouch than other packaging materials.
Application-
- These are used as a barrier layer in two and three layer flexible packaging
- Suitable for hot fill applications like liquid juices, jellies, tomato ketchup etc.
- These are widely used for laminates for coffee, milk powder, juice powder, tea, cereals, malt based food powder, dry nuts, cosmetics and personal care products.
- Replacement of aluminum foil in flexible packaging where dead fold is not required.
So, you can now see the different uses of metallized polyester films manufactured by Metallized polyester film manufacturers and the various advantages of these films.
