>Polyester Film for Encapsulation has been going through some major changes
>within the past few years.
>A few years ago the ICI Melinex line of film was purchased by the DuPont
>Corporation. I thought that the Melinex line would be dropped. However,
>Melinex Type 516 has lived on at DuPont. Now, there is new information from
>DuPont, that Mylar Type D will be discontinued as of September 2001. Mylar
>Type D had been developed for the Graphic Arts Industry. They are now using
>computers for most of their work so there is little call for Mylar D.
>According to DuPont, converters/our suppliers have been alerted to the
>discontinuation of Mylar D and they have "developed a game plan". Melinex
>Type 516 and another similar film, 456, should be readily available for use
>in preservation. Those of you who use DuPont Mylar Type D should contact your
>supplier for new information.
>I will try to gather more information as it comes available.
