Mylar

From DictionGloss

Invented in the 1960s. Mylar is the proprietary name for sheet polyester, an inert materials in which fragile documents are often stored. With the advent of Mylar, the need for lamination became obsolete.

Mylar is a DuPont trade name for a plastic polyethylene terephthalate (polyester) sheet, commonly used for mapping field projects. Mylar is characterized by its transparency, colorlessness, high tensile strength, and chemical stability.

Mylar may be used by artists in a number of ways: it can be drawn on or serve as a printing element. Alternatively photo stencils may be cut out of it or it may also be used in place of paper as a substrate for a drawing or painting.
