Zip Lock bags for storage
 

I've received stamps in Kitchen "Zip-Loc" bags and store some
common used stamps in them.

How safe or how bad are Zip Loc bags for stamp storage of extras?

Thank you,
Steve

Good question,
I have recently been through I phossick box I bought
at auction, that has approval sheets in cellophane.
Presumably some had been sealed in the 60's
and have travelled extremely well, seemingly
pristine after all these years in a medium by all accounts
is not well advised.
I have most of my collections in glassine, yet just yesterday
found a site that advised, "under no circumstances" keep
stamps in these see through envelopes.

Unless the bags are marked "archival quality" I suspect that plasticizers have
been used in the manufacture of the material. This is known to have deleterious
effects on stamps.

I think this depends on
how common are the stamps? and
how long are you going to keep them.

I keep my collection of bulk mail and 37cent flags that I am checking
for varities differently than I keep my US C3a and my 1 cent magenta
British Guiana. g
