In my small mind, if you want to keep your seed faces safely on paper, then you should definitely laminate it after writing it on paper. Because it is more likely to get wet in water than to catch fire. And in my opinion, it is important to keep a backup of your seed face in several places. Because accidents come unexpectedly. So in my opinion, if you save it on an offline laptop or mobile at home and also save it on paper, then it is better.
Lamination is indeed a good first step to secure the paper so that it does not get damaged easily and fade,
but of course this is only the initial protection that will not even always be reliable when some other damage can occur such as burning or some other more extreme thing.
Having a lot of backup in one place should also think about how well the paper holds.
As mentioned above and I also said, moving the storage to a steel plate will be better because it is more resistant to all kinds of damage,
but you will certainly need to spend more to buy a steel plate, or you can make your own with a steel plate ring and print a phrase on each part of the steel plate ring.
Spending a little money is better than keeping all the backups in the same condition, but in the end they are damaged and unreadable.
