Here are the instructions for storing paper pulp cut & pasted from
Twinrocker. Twinrocker's web site is

Twinrocker is the primary source for hand papermaking materials in the U.S.
They sell beaten pulp by the bucket, and also a large variety of dried
fibers from beaten denim to hemp to pure flax, also for Asian papers like
kozo. And linters. And a mind-boggling assortment of other supplies &
resource materials. If you are at all interested in making real paper, (not
just chewed up newspaper), be sure and check out their site. This site, by
the way, has excellent photos of the hand papermaking process.

If you cannot use your pulp at one time, it is possible to store it for a
while. An unopened pail of cotton linters pulp will last up to several
months, if kept cool.
Opened pails won't last as long, due to molds & spores from the atmosphere.
While you are using it, make sure your hands and your tools are clean.
Reseal the lid as soon as possible.
If you must store your opened pulp for a long time, add a capful of chlorine
bleach to a gallon or two of water. Add to the pulp and stir thoroughly. Let
it sit for awhile, then rinse it thoroughly in clean water. Any un-rinsed,
residual chlorine bleach can attack the fiber, however. If you are truly
concerned about the archival qualities of your paper, don't use bleach,
order the amount of pulp you need when you need it.
Cotton pulps are the only ones that will last for more than a week or two.
Fibers such as flax, abaca, hemp, etc. just won't last...use immediately!
You can freeze pulp. After defrosting you must use a mechanical stirring
device such as a paint stirrer chucked into an electric drill to get the
lumps out.
