Milar is a brand name for a polyester film manufactured by DuPont Teijin Films. The material is a biaxially oriented polyethylene terephthalate (BoPET) film known for its strength, stability, and transparency. Milar film is used in a wide variety of applications due to its unique properties. These include its excellent tensile strength, resistance to chemicals and moisture, and its ability to withstand a broad range of temperatures.

Industrially, Milar finds use in electrical insulation, as a component in capacitors, and as a backing for magnetic recording tapes. In the packaging industry, its clarity and barrier properties make it suitable for food packaging and lidding films. It is also employed in graphic arts, such as for overlays and stencils, and in the production of labels and decorative films.

Beyond industrial uses, Milar is recognized for its application in art and craft projects. Its durability and smooth surface make it a popular choice for tracing, drawing, and for creating protective coverings. The film's archival quality also lends itself to preserving documents and photographs. Milar is available in various thicknesses and surface treatments to meet specific application requirements, further contributing to its versatility across numerous sectors.
