Coated paper

Various materials, including kaolinite, calcium carbonate, bentonite, and talc,[2] can be used to coat paper for high-quality printing used in the packaging industry and in magazines.

The chalk or china clay is bound to the paper with synthetic viscosifiers, such as styrene-butadiene latexes and natural organic binders such as starch.

The coating formulation may also contain chemical additives as dispersants, resins, or polyethylene to give water resistance and wet strength to the paper,[3] or to protect against ultraviolet radiation.

They have good surface properties, high print gloss and adequate sheet stiffness.

In this case, the remains of the non-biodegradable plastics components form part of the global microplastics waste problem.

A release liner is a paper (or film) sheet used to prevent a sticky surface from adhering.

Heat printed papers such as receipts are coated with a chemical mixture, which often contains estrogenic and carcinogenic poisons, such as bisphenol A (BPA).
