Vinyl

In response to Marsha Maquire's inquiry on "clear vinyl" pockets,
offgassing set aside, vinyl is known to interact with the polymers
in toner used in photocopiers and laser printers. Over time the
toner begins to stick to the vinyl causing the print to be pulled
away from the paper. You should look for pockets made of polyester
film.
