Mylar is an extraordinarily strong polyester film that was developed in the
early 1950s. During the 1960s cellophane gave way steadily to Mylar with its
superior strength, heat resistance, and excellent insulating properties. The
unique qualities of Mylar made new consumer markets in magnetic audio and video
tape, capacitor dielectrics, packaging and batteries possible. By the 1970s,
Mylar had become DuPont's best-selling film. Mylar is now a product of a joint
venture, DuPont Teijin Films.
