Mylar is an incredible space-age polyester developed by Dow Chemical in the 1950s. You can see the Mylar specs here. While most commonly associated with space blankets and helium balloons, Mylar has actually become a fantastic substrate for label printing.

Mylar Provides Durablity:
While it appears flimsy, Mylar is actually a relatively durable material and makes for a fairly sturdy Mylar label. As you might expect for a material designed specifically to have strong thermodynamic properties, the great advantage of Mylar is its resistance extreme heat (over 300 degrees) and electricity. For this reason, it is often the substrate of choice for ovens and stoves, radiators and furnaces, around the motors and engines, and on some medical devices, space heaters, hair dryers, solar heaters, crock pots, and other devices capable of producing extreme heat. It is also resistant to many chemicals, lubricants, solvents, and outdoor elements. In fact, UL has approved Mylar labels for indoor/outdoor use and occasional exposure to a wide variety of chemicals. Mylar labels are both chemically and dimensionally stable, with both mechanical and dielectric strength. A Mylar decal has low water absorption capabilities and is a remarkably good electrical and heat insulator. That makes flimsy looking Mylar a surprisingly durable substrate for custom label printing.
Mylar is an Ideal Printing Surface:
Mylar retains it’s clean, smooth finish regardless of printing methodology. The ink-receptive surface is designed to be compatible with most inks, including specialty UV inks. Thus, when choosing inks for the project, Mylar enables you to select the colors and types of inks you prefer without regard for the substrate, since it is compatible with so many inks.
Mylar Makes for Great Custom Labels:
Mylar is flexible, and able to conform to virtually any surface you put it on. At the same time, it has high tensile strength, dimensionally stability, and heat resistance. That is a rare combination, which makes Mylar ideal for a number of different label applications. What’s more, Mylar is compatible with a wide variety of adhesives. That makes a Mylar label a truly versatile label indeed.
