Lamination with Japanese paper
Lamination of valuable documents with two-layer Japanese paper. There is an adhesive on one side of the Japanese paper that activates when heated, so the document is sealed on both sides. This type of lamination is absolutely harmless.
The good thing about this type of lamination is that the cover layer can be removed without damaging the document.
The difference with ordinary lamination, which we have all seen, is that no plastic is used here, which is harmful.
Lamination with Japanese paper is extremely fast and the original lasts for decades.
