Special Issue Information
Dear Colleagues,
Paper coating is a finishing process in which the optical and printing properties are improved and the physico-mechanical properties deteriorate. The finishing process transforms the printed product into an end product that must not be damaged in any way. To prevent the surface of the coating from being damaged during bending and folding, the paper/cardboard must have the properties of layering and even distribution of forces on the outside. The negative effect is also reflected in the appearance of the end product, as it leads to various complaints that manufacturers want to avoid.
Coated papers must have the ability of an elastic body, which is largely influenced by the choice of components of the coating mixture. The choice of pigments depends on the amount of deformation of the paper/board. Calcium carbonate is the more suitable choice for higher loads as CaCO3 particles tend to have a round, isometric shape and therefore do not damage the fibres, whereas kaolin particles have a flat shape which damages the fibres more quickly but offers better resistance to cracking when the particles are loaded axially during bending. Starch is used more often due to its low price, which is important for the production process, but due to the low elastic properties of the binder, it more often leads to damage to the coating, i.e., cracking. When folding the paper/cardboard in the finishing process, other parameters must be taken into account to avoid damage to the coating, e.g., the surface mass of the base paper, the amount of coating, the stiffness and thickness, as well as environmental factors such as temperature and humidity, the structure of the coating, which consists of natural or synthetic compounds, etc. In this Special Issue, we would like to encourage you to share with us your research results in the field of the influence of coating chemistry on the final use in paper/board and printing production.
The theme of this Special Issue broadly includes (but is not limited to) the following:
- Natural, synthetic and/or renewable coatings;
- Eco-friendly coatings;
- Packaging application of coated polymers;
- Evaluation of print quality on coated surfaces;
- Novel evaluation methods for the characterization of coated surfaces.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
