Polyester Base
Polyester Base – Polyester base is a very durable type of film, that is virtually unrippable. Some people claim that it is harder to splice, but that is more a matter of getting used to the technique. Significantly, it cannot be Cement Spliced, making it impractical as original material (also, its durability could spell disaster for the delicate mechanism of a camera in the event of a jam). However, its durability makes it very advantageous for release prints.
