Polyester Film, Mylar® Polyester Film, and DuraLar™

The Versatile Wonder

The term “polyester” film most commonly refers to the polymer polyethylene terephthalate (PET). The go-to commodity film for many every-day products for over 30 years, polyester makes an excellent multipurpose film because of its high mechanical strength, durability, heat tolerance, chemical resistance, and dimensional stability. You’ll find polyester in fabrics, finishes on high-quality wood products, beverage and food containers, and insulation for cushions and pillows.  You probably have heard the brand name Mylar® often used to generically describe plastic film.  However, Mylar® is really a brand name for polyester film.

So many varieties to choose from!

Mylar® (Polyester Film)?

“Mylar” is a term often incorrectly used to refer to ANY type of plastic film. In reality, Mylar® is a registered trademark for a brand of biaxially oriented polyester film (BOPET) that belongs to Dupont/Teijin Film Enterprises. There are about 20 different grades and finishes Dupont/Teijin offers under the Mylar® brand.

Grafix Plastics offers several of the more popular versions of Mylar® brand, including Mylar® A film. So if you have a need for honest-to-goodness Mylar® polyester film, we can help, whether you’re referring to “Mylar” in the generic sense, or you actually need Mylar® polyester film from Dupont/Teijin Film Enterprises.

DuraLar (Polyester Film)!

Grafix Plastics offers its own branded polyester film product called DuraLar, as well as brands like Mylar®, Melinex®, Hostaphan®, Skyroll®, and many more.
