Print lamination is a finishing process that involves applying a thin layer of plastic to paper or card sheets to protect and enhance printed materials. The plastic, known as a laminate, is bonded to the paper using heat and pressure. Lamination can be used for many purposes, including: 

Protection
Lamination can protect printed materials from moisture, dirt, spills, and general wear and tear. It can also protect against smudges, stains, and tears. 

Durability

Lamination can extend the life of printed materials. For example, nylon lay flat lamination can help book covers last longer. 

Enhanced appearance

Lamination can give printed materials a more professional and polished look. For example, gloss lamination reflects a lot of light and gives items a shiny quality. Matt lamination is non-shine and creates a more subtle effect that is easy to read and glare-free. Soft touch lamination is a type of matte laminate with a smooth and velvety texture that can add tactile appeal. 

Lamination is often used for packaging, book covers, brochures, and business cards.
