[Nhcoll-l] question about polyethylene bag "tubing" for specimens

[Abraczinskas, Laura]

Dear NHColl list members,
I am seeking advice about sealing specimens within polyethylene bag "tubing" for temporary storage during a collections move.  This is an example of the "tubing", which is a roll of open-ended polyethylene bags that contents are sealed within by use of a heat sealing machine.  (We have a tabletop impulse sealer).

The Michigan State University Museum is preparing for a temporary move of the dry vertebrate collections before a building-wide HVAC renovation project begins!  Specimens will be temporarily stored off site for about 18 months. Specimens will not be stored in their usual cabinets but packed into boxes or other containers and secured at an art storage facility with climate control.

We are wondering about use of this product for bird and mammal skins or taxidermy mounts, or other dry specimens. The vendor has asked that we bag and seal anything that may contain arsenic before it is housed at their facility.

We are thinking this might be good for pest management too, during the temporary storage.

Does anyone have thoughts about this idea?  If a go, would 4 mil polyethylene be recommended, rather than 2 mil?
If the Uline product is not appropriate, is there another recommended source?

Thanks so much!
Laura
