It occurred to me to look for sites in Spanish mentioning this paper, and I found this:

http://www.corporaciondeoriente.com.mx/papelbn.html

They describe Fomalux as "made especially for Corporacion de Oriente", so I guess they are the Mexican market driving the production of the paper. I just glanced very briefly around the site, but it looks like they're basically a wholesaler to photo processors. I don't know why processors in Mexico would have a particular need for a contact paper, but I must say I'm glad that they apparently do...
