Thank you, Lisa, Adrian, Margaret, and Maria! I am ever so glad that I joined this listserv! Sounds like Uline is the place to source, for sure. With so much appreciation Rachel

Greetings all, We've increased our use of poly sleeves in cases where sourcing a large enough resealable bag was tricky (essentially making our own bags). And now use them almost exclusively as they save so much labor and cover most of our object size ranges. This greatly reduced our usage of tape as we heat seal the two open ends (sealing with two parallel lines, spaced ~ 1/2" or 1.5cm apart). Could be an option for you all as well. We also source from Uline<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.uline.com%2fBL_2107%2f4-Mil-Poly-Tubing&c=E,1,BpxbYIYsFNTkAYKjiLUy2z05eHzlv9hzYHDnGUC9IIA71i3ovse5ls_eeUjZJj0oUeoARUhoEwGk1NLbPQpIgXguCQbYQN4J56sikACx2OmrHUb1y_A,&typo=1>. They have nice 4mil and 6mil thicknesses. We've found the 18" and 40" wide sleeves rather flexible in containing rolls and even large boxes, but even wider sleeves (and indeed, wider heat sealers) are available. We use this heat sealer.<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.uline.com%2fProduct%2fDetail%2fH-1029%2fPoly-Bag-Sealers%2fTabletop-Impulse-Sealer-20%3fkeywords%3dH-1029%2bTabletop%2bImpulse%2bSealer%2b-%2b20%2522&c=E,1,L3otHETtOMA_vrlKmkZzt4C0pYJG_SSqLME30OONJL3kxL_ZsIfxS7DCLOy3lL_wmGpm-IU_SYLA9iWSGyZ03PxrBFG8NinhT12f1NwYwy1k23gMjQ,,&typo=1> Another advantage, heat sealing is oddly meditative in these strange times. Hope this helps!

However, we did note the following things to be aware of when freezing and perhaps someone can fill in the gaps as I don’t have the research any more. 1. Check the thickness of the polyethene and go for something which is a thicker grade plastic as it helps prevent moisture transmission 2. Check that the seals are well made as some of them are pretty thin and will tear easily. 3. Zip loc seals are not moisture resistant and need to be taped over as well Hope that helps Adie Doyle IPM Manager British Museum From: 'Oliver, Margaret' via MuseumPests <[email protected]<mailto:[email protected]>> Sent: 08 December 2020 22:06 To: [email protected]<mailto:[email protected]> Subject: Re: [PestList] Source for Polyethylene bags for Freezing objects I also use bags from Uline for the freeze/thaw cycle (specifically, these 30"x36" 8 mil poly bags https://www.uline.com/Product/Detail/S-12510/Flat-Poly-Bags/30-x-36-8-Mil-Poly-Bags?keywords=S-12510<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.uline.com%2fProduct%2fDetail%2fS-12510%2fFlat-Poly-Bags%2f30-x-36-8-Mil-Poly-Bags%3fkeywords%3dS-12510&c=E,1,cOfySFP6p6Dv_tG0uEeB-jCNGMZI5gmmir4UlnK7PHd0aU3Z-q6tGYc-aYeaBgtcRfd9CNYcm2ZXFrES-7umKDdhz3YpUfJ4eGNj7sdPIcg,&typo=1>).

Some of these get up to a sufficiently large size easily to hold a full sheet of matboard or an archival box. Disclaimer: I am not aware of any testing having been done on these (for additives, plasticizers, etc.) However, if one is using this only for a freeze-thaw cycle (and not for long-term storage) it may be justifiable.

I am waiting for our new chest freezer and am now researching polyethylene bags or film for wrapping objects to be treated. I appreciate any advice on this. I am finding lots of smaller zipper heavy 3 – 4 mil bags available but I will also be freezing larger objects, and wonder if you recommend and type of film and a tape that can withstand the deep freeze. Should objects be airtight before freezing, or just well covered?
