but doesn’t the printed text fade away before then?
The short version is you should use archival grade acid-free paper (acid breaks down ink and the page over time) and prefer encapsulation (storing inside an intert sleeve with the end taped or threaded closed) over hot lamination (the vinyl acetate in the laminate accelerates degredation).
We have managed to keep documents much older than 100 years in usable condition under far less ideal circumstances.
