Metallized DuraLar™ Product FAQs

Can metallized DuraLar™ polyester film be recycled?

Can Metallized DuraLar™ polyester film be recycled? No, not in the traditional sense. The metallized coating on this film is a contaminant that will fowl up the recycling process.

Do any of our polyester film and sheet based products, such as DuraLar, Mylar® plastic film, and others, resist tearing?

Do any of our polyester film and sheet based products, such as DuraLar, Mylar^® brand and others, resist tearing? Yes, they do. Polyester film is one of the most tear-resistant materials we offer.

For more information on how DuraLar can work for your particular application, please contact us with your requirements.

Are any of our polyester film and sheet based products, such as DuraLar, Mylar® plastic film, and others, biodegradable?

Are any of our polyester film and sheet based products, such as DuraLar, Mylar^® brand, and others, biodegradable? No, they are not. The only biodegradable film product we offer is acetate film and sheets.

Does Metallized DuraLar™ reflective film have good insulation properties?

Does Metallized DuraLar™ reflective film have good insulation properties? Yes! Its combination of thermal and barrier properties make it an excellent film for many thermal insulation applications. Its metal coating also acts as a barrier enhancement, while reflecting in-frared radiation. All polyester films have very good insulation properties; Metallized DuraLar takes that performance to the next level.

Does Metallized DuraLar™ film have good electrical properties?

Does Metallized DuraLar™ film have good electrical properties? Depending on what electrical properties you need. Metallized DuraLar is made from our Clear DuraLar base film. So the film itself has excellent resistive electrical properties (acting as an insulator). The metal-coated side of the film is very conductive. With Metallized DuraLar you get the best of both worlds. If that’s what you want.

Is Metallized DuraLar™ film approved for direct skin contact?

Is Metallized DuraLar™ film approved for direct skin contact? Although Metallized DuraLar is perfectly safe for direct and indirect skin contact, it is not certified as such.

Is Metallized DuraLar™ approved for direct food contact?

Is Metallized DuraLar™ approved for direct food contact? No, it is not. Grafix regularly carries other types of film products that are approved, including acetate, specific brands and grades of polyester film, HDPE and polypropylene. Unfortunately most of these materials are available with a metallized coating. Other types food-safe films are available as a custom order; larger pro-duction minimums may apply.

Is Metallized DuraLar™ suitable for outdoor exposure?

Is Metallized Duralar™ suitable for outdoor use? No. If sub-jected to sun and rain, the aluminum metal level on top of the film will corrode and fade quickly. This is not an appropriate film for outdoor use.

Looking for film products that perform well under longer term outdoor or UV exposure? Check out our HDPE and Polypropylene product pages.

What is the heat resistance of Metallized DuraLar film and sheets?

What is the heat resistance of Metallized DuraLar™ film and sheets? Metallized DuraLar will begin to soften at about 150C/300F. When Metallized DuraLar softens, it begins to lose its orientation; the metal coating will crack, and the film gets wavy and begins to shrink. So if your film will only be exposed to a heat environment below 150C/300F, Metallized DuraLar is a good choice.

Need to thermoform? Polyester films like Metallized DuraLar don’t thermoform too well because of their crystalline structure. Try our Clearlay, Acetate, HDPE and Polypropylene sheets and film for your thermoforming applications.

Is Metallized DuraLar™ archival?

Is Metallized DuraLar™ archival? No. There are three aspects that go into determining whether a polyester film is actually archival grade: 1- whether it is pH neutral, 2- whether or not the film will impact what it comes in contact with, and 3- whether it can be sonically welded to itself. Metallized DuraLar is a pH neutral polyester film that will not stick or transfer to other surfaces. However, metallized DuraLar is not treated so that it may be sonically welded to itself, and its aluminum metal coating will oxidize over time.

How will you be using this film in an archival application? If you need a good archival grade film, try our Archival Duralar™ product line, which meets the Library of Congress’ specifications for archival polyester film.
