What is Veltique paper?

This is the paper the new LOTR illustrations were printed on, and the Plants of America LE uses this paper. Anyone know anything about this paper (e.g. is it 100% cotton etc.) and how often has FS used it? Google does not help.

>1 punkzip: A search on FS and Abebooks with 'veltique' as the keyword revealed the following:
- The Life and Opinions of Tristram Shandy, Gentleman, 2020 LE (10 illustrations printed on Veltique paper)
- Plants of the Americas, 2020 LE
- The Toilers of the Sea, 2014 LE
- Goya: Disasters of War, 2013 LE
- TLOTR, 2022 LE (53 illustrations printed on Veltique paper)

..and of course this post on the FS Twitter website: https://twitter.com/foliosociety/status/1192056182615289856

google search gave me this snippet:
