Lamination refers to the technique of applying a thin layer of plastic film over printed pages or covers of children’s books. This process enhances the durability of the book, making it resistant to wear, tear, spills, and fingerprints. While lamination can add a glossy or matte finish, it also helps preserve the vibrant colors and illustrations typical of children's literature. Overall, lamination is especially beneficial for books aimed at younger audiences who may handle them roughly.
