i was considering laminating my paper wallet but that would require me to go out to a "laminating shop" (i don't know what it is called in English) and ask them to do it and that already compromises me even though i can be 99% sure the person doing it won't have slightest idea what it is i have written on paper
you can encrypt it with a password and then do it though, but i didn't.
i just settled for simple writing down my seed (or it can be private key) on a paper! simple! and it has been 2 years and the paper is still fine.
i should add that is not my only back up, but it is my only physical backup.

don't leave your paper in the garden.
Good job, I confuse why so many people being skeptical and paranoid, different with aware as precaution act and be careful.
Paper wallet should be safe as long as no one in your home remove it, put it save and it will be fine.
Laminate or sealing/coating it with resin are good enough, if you could make it by yourself is better than risk it to laminating shop.
