[Nhcoll-l] freezing the herbarium

[Lennart Lennuk]

Hi!

I found out that our herbarium curator uses black carbage bags that producer claims to be from PE for freezing process.
Are those safe? I doubt that the Black ones consist also something else than just PE.

What are good practices for freezing herbarium? Are there any big and easily opening PE bags in europe?
Has anybody used plastic boxes with sealed closure?

Best regards!
