What is Mylar or Mylar Film?

Mylar or Mylar Film, also known as BoPET (Biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET). Mylar film itself is polyester film. So the true generic terms for this material are either polyester film or plastic sheet.

Mylar Polyester film/plastic sheet is manufactured in a range of different styles, finishes, and thicknesses, and many applications.

What is Mylar Made of

To make Mylar, super-heated polyethylene terephthalate (PET) film is put on a roll and stretched. One side is smooth, but the other is not so that it can be applied more easily as a coating to various products, such as paper.

Molten polyethylene terephthalate (PET) is extruded as a thin film onto a chilled surface, such as a roller.

The film is drawn biaxially. Special machinery may be used to draw the film in both directions at once. More commonly, the film is drawn first in one direction and then in the transverse (orthogonal) direction. Heated rollers are effective for achieving this.

Finally, the film is heat set by holding it under tension above 200 °C (392 °F).

A pure film is so smooth it sticks to itself when rolled, so inorganic particles may be embedded in the surface. Vapor deposition may be used to evaporate gold, aluminum or another metal onto the plastic.

Why Choose Mylar Film?

Mylar polyester film is one of the world’s most recognized and widely used polyester films.

It has been a prominent film in a variety of applications across electronics, food packaging, industrial specialty, cast & release, and graphics markets due to its balanced tensile properties, good adhesion, excellent moisture, and chemical resistance.

Mylar polyester films are ideal products for high volume, dependable industrial performance, where lower-cost initiatives must be met.
