Providing an "air tight" seal for a large tub is far more challenging than snapping a gasketed lid onto a small box. For a truly air tight solution, you should consider a flexible (plastic) envelope. I don't think you will find a large, truly air tight container at reasonable cost. If you decide to bag the artifact(s), you need to consider the materials used to make the bag, and your expectations. Are you simply protecting from air currents and dust (short term work like freezing or construction dust protection)? Will offgassing from the plastic (or its plasticizers) be a hazard? Are you concerned about chemicals/odours/moisture permeating the bag (in or out)? Would it be useful to create an anoxic environment? If storage is temporary, you will have few worries, but if it is a long term application, it would be worthwhile to investigate barrier films and heat sealers. js Jerry Shiner Keepsafe Microclimate Systems 800 683 4696 www.keepsafe.ca i...@keepsafe.ca Specializing in the design, procurement, and installation of environmental control systems in museums and archives. -----Original Message----- From: ad...@museumpests.net [mailto:ad...@museumpests.net] On Behalf Of Neil Carey Sent: Monday, August 27, 2012 4:36 PM To: pestlist@museumpests.net Subject: [pestlist] Plastic containers This is a message from the Museumpests List.

Thanks for your post re: Lock&Lock plastic containers. I looked at both your Amazon link and at their own website. They seem ideal for small items, but I could not find any large enough for larger objects. We have many pieces that barely fit into a 24" x 36" polyethylene bag, and some Kpelle masks with feathered coifs approach 40". The larger pieces can always be handled individually, but I wonder if there are 18-24" x 30-36" containers similar to the L&L that could accommodate the bulk of our collection. Having transparency, a good seal, being nestable and stackable with enough capacity seems ideal.
