[Nhcoll-l] Temporary storage of herbaria sheets in sealed plastic bags

[Anita Cholewa]

When we were installing a compactorized system in part of our herbarium, we
had to temporarily store some specimens and used bags and boxes (bags
inside boxes).  Since the specimens were already dried, it worked very
well, limited handling, and controlled pests.  No vacuum was necessary.
