Tyvek as Storing and Backing Material
« on: June 23, 2024, 05:42:42 AM »
Hey all, first post here and decently new to poster collecting.

With getting a few rarer examples Ive been more conscious of how I store and frame my pieces and researching a bit I realized I should probably get some acid free backing for my frames instead of just relying on the masonite or dense cardboard esc backings I have now.
I was thinking I could probably DIY a solution by using a safe plastic as a buffer between the poster and card backing but then I also came across a site offering the material Tyvek as backing material:
https://www.universityproducts.com/tyvek-frame-backing-paper.html

"A unique frame backing material that is acid-free and contains no damaging chemicals that can affect framed artwork. Tyvek is easily cut and worked like traditional paper frame backing material, yet is puncture and moisture resistant and won't attract insects. White. Price per 36'' x 70 yd. roll."

I cant find much else mention of it so I doubt many actually use it but on the off chance that someone here has good knowledge for or against this material I thought Id ask. The reason is because I do have a quite easy way of sourcing this material and it would be a really convenient solution for me.

Thanks!

Hi LeonTP,

I'm not sure of the archival properties of Tyvek type materials, though Tyvek is used to wrap houses before putting on the siding to help keep out wind and moisture.  I've used it before on building projects. You can buy Tyvek type materials at home improvement and local building supply stores.  My best, Okie

Thanks Okie!
Yeah from what I know its essentially a sort of plastic paper. I suppose the real question is if you want to completely seal the poster away or allow the tiniest of breathing.
Because I could just sandwich the poster between the:
Acrylic - Poster - Plastic
I suppose the tyvek would be more like a linnen backing but maybe it also doesnt matter as long as it doesnt contact harmful surfaces.
I already cut up a few pieces of tyvek though so I might as well give it a try.

Hi LeonTP,

Something you may want to consider, since paper needs to shrink and expand based on temperature and moisture changes in the air, I would recommend allowing enough freedom for your posters to be able to shrink and expand, if not they will wrinkle.  As long as they are not stored too tight, hopefully you will be okay.

You may also want to look at cotton based archival barrier paper as your buffer material between your posters and non-archival frame backing. There are many sources where you can get different sizes of archival cotton barrier paper.  Also, you can get archival pH buffered foamcore online shipped to you and cut it to size yourself and use for backing for framing. I've done this and am very happy. It's been a while since I've ordered some, though art supply stores like Michaels in the U.S. sometimes have some in stock and or could order for you. I'm also thinking Sue Heim at Hollywood Poster Frames may be able to sell you some archival foamcore and perhaps even cut them to the size you want.

My best wishes on your poster adventures, Okie
