Coating is formed by pouring a liquid film onto the paper and drying. The cost of the coating is relatively low, but the requirements for the base paper are relatively high, and ordinary paper cannot be coated. The production process of coated paper is made by pouring a liquid film, which generally has a waterproof effect. Paper cups are the best example.
Lamination refers to the application of transparent plastic film to the surface of printed matter by hot pressing. The thermal film is thin, has good light transmission, and has a long storage time. It has low requirements for paper, but the relative cost is high. Once the lamination fails, the film cannot be peeled off. Generally used for printing, one-time molding, as the name suggests, covers the top of the ink layer, and is not easy to get dirty.
Coated paper is usually used in the packaging field. For example, the raw material of corporate promotional paper cups is single-side PE coated paper roll, and the interior is waterproof through the coated layer. It can hold water for a long time without leaking and seeping water, ensuring the stiffness of the paper cup wall. The material of the coating is generally polyethylene.

Laminated films are divided into glossy lamination or matte lamination, which are generally used in the field of corporate business printing, such as commonly used promotional printed materials for companies: business cards, folders, single pages, album covers, product packaging surfaces, etc. The material of this film is generally PET (polyethylene terephthalate). After printing, it is attached to the paper, which prolongs the service life of the printed matter, at the same time, it plays the protective role of moisture-proof, waterproof, wear-resistant, and folding-resistant, which can improve the user’s experience and improve the quality of printed matter.
