Hot lamination is a process used to protect and enhance documents by sealing them between layers of plastic. This method involves applying heat and pressure to bond the plastic film to the document, creating a durable and waterproof finish. It is commonly used for items like ID cards, certificates, and posters. The hot lamination process typically requires a laminator machine, which heats the plastic film and applies it to the document. This technique not only preserves the document but also improves its appearance, making colors more vibrant and text clearer.
