PET
Abbreviation for polyethylene terephthalate, the polymeric substrate material used for most magnetic tapes. Polyester is another material used to make safety base films.
Polyester was first developed in the late 1940s — the extreme resistance to tearing made polyester an ideal film base, able to withstand the rigours of commercial cinema projection. Since the early 1990s PET has become the base of release print materials.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
