Types of coated papers

One of the key differences between types of paper is the process and the machine on which the paper is produced.

Paper formats

The most well-known series of formats is the basic A series. This includes formats such as A3, A4, or A5, which are commonly encountered in magazines, notebooks, drawings, etc. Other frequently used series include the B series (B0, B1, B2,...), the C series, and the D series. C series formats are mainly used for envelopes.

Calculation of the weight of sheets

The weight of a paper sheet can be calculated using a simple formula. You just need information about the basis weight (or grammage) and the paper format (e.g., A4). Not only is it very simple, but we have also already calculated some values for you and recorded them in a clear table.

Paper grain direction

During paper production, paper fibers are predominantly oriented in the direction of the paper machine's travel. From the resulting parent roll of paper, sheets are then cut, which are distinguished into sheets with a narrow grain direction or sheets with a wide grain direction depending on the fiber orientation. The properties of paper with different grain directions vary, which is often important to know during paper processing.

NCR carbonless papers

NCR or carbonless copy papers work based on the reaction between encapsulated dye and a layer of clay. Microcapsules containing dye break under increased pressure (through writing), and the dye reacts with the clay. Individual papers CB, CF, CFB, SC, SC/CB differ in their functional properties.

Types of paper for the production of corrugated cardboard

Corrugated cardboard is produced by gluing flat paper (covering paper) and corrugated paper (wool). According to the number of layers, it is divided into 2-layer cardboard, 3-layer, 5-layer and 7-layer (see the picture below). A straight layer is always alternated with wool.
