Mylar polyester films are used in a wide variety of applications. One application that may not be as widely known, but is a growing market is stencils. Many people think of crafters when they think of stencils, but the handy tools are gaining momentum in home décor (think tile and backsplashes) and businesses (wayfinding signage) and even by DIY clothing designers to create unique fashions. Two of the most common stencils are plastic stencil sheets and metal stencil sheets.
What is a Stencil?
Mylar® A Translucent Polyester Film – The Stencil Makers Go-To-Material
One of the most common materials used to create stencils is Mylar A polyester film. These translucent films are tough, general-purpose films and that have many attributes that make them well suited for stencil making:
- Allows stencil makers to create very sharp edges
- It enables stencil makers to achieve crisp points particularly when working with patterns with minute details via a variety of cutting methods including laser cutting and knife-plotter cutting
- Mylar is a versatile film, which allows for it to form to irregular shapes or to be rolled around cylindrical shapes
- Even when using a thin material, such as 10 mil Mylar, it is durable, does not become brittle with age, and is a long-lasting film that can be used multiple times
- It has excellent resistance to most chemicals making it easy to clean
- It comes in a variety of thicknesses
- It is a cost-effective material
Thin Thickness – 5 mil and 7.5 mil Mylar
Mylar PET plastic sheets for stencils comes in thinner material such as 5 mil and 7.5 mil. This film is durable but very flexible so it can be wrapped around cylinders and fit on curves. This clear material is particularly good for a variety of applications including when applying ink or paint by sponge, brush, spray, or roller. 5 mil and 7.5 mil are generally best when using smaller stencils or if the stencil needs to have smaller, minute details.
Medium Thickness - 10 mil Mylar
One of the most common thicknesses that we see used by Stencil makers is the 10 mil Mylar stencil film. This clear material is particularly good for a variety of applications including when applying ink or paint by sponge, brush, spray, or roller. The 10 mil Mylar is generally best when you are using smaller stencils or if the stencil needs to have smaller, minute details. The thinner material generally will provide crisper lines.
Heavier Thickness - 14 mil Mylar
Some applications, especially those requiring larger designs, may need a thicker material such as 14 mil Mylar. This thicker Mylar is particularly good with larger stencils that will go on more uneven surfaces. The thicker material works best when applying ink or paint via a spray or roller. Thicker polyester materials may not give as crisp of lines as the thinner gauge polyester.
