Photographic sleeves

Polyester or other inert/chemically stable plastics that filter UV
radiation should not be used to store records for any extended length of
time.  UV filtering plastics are useful for exhibit and treatment
action, but not for storage.  UV filtering should be regarded as an
"additive"--and an impermanent one.  UV filtered plastics are generally
only effective for a limited period of time (7-10) years.  UV filtering
on a plastic enclosure for storage purposes should certainly not be
regarded as a bonus.
