Plain paper – A type of paper intended for typographic printing. According to the PN/P-95001 standard, it is manufactured in classes III, IV, V, VI and VII.
This paper is not used in practice in Class V. Filled with kaolin representing 13-17% by weight of paper. Matt surface, obtained on a machine trackpad with metal rollers, or satin surface, i.e. with a higher gloss and smoothness, obtained on calenders. Self-determination in both directions shall be not less than 2 600 m in Class III and 1 900 m in Class VII.
Custom printed boxes are used for this purpose
Plain paper is not glued and is not suitable for ink writing.
Synthetic paper is a synthetic imitation of paper made of polymers, e.g. polypropylene with inorganic additives and fillers. Unlike papers made on the basis of natural fibres, synthetic paper is very resistant to chemicals, UV rays, water, grease, tear resistance. These features make it a good material for the production of e.g. maps, instructions, tags. It combines the advantages of a durable film with the appearance and texture of paper and can be printed and processed after printing on a paper pattern. custom printed boxes
A distinction is made between single- and multi-ply, coated and uncoated synthetic papers. Synthetic paper was made in the 1960s. It is used not only as a printing substrate, but also in other applications, e.g. replacing traditional Japanese paper in modelling (synthetic Japanese paper). There are also semi-synthetic papers: the two layers of cellulose are separated by a layer of polymer film.
Preshpan – a type of multilayer, strongly pressed cardboard in which the raw material is paper with a thickness from 0.1 mm to 50 mm. The surface of the gazebo is smooth and impermeable. It has a high mechanical resistance to abrasion and bending.

Precious fibrous materials are used in the production of ‚preszpan’ in the form of semi-mass cotton, hard cellulose and waste paper. The thinnest EPS were produced on flat-plate machines, while the most popular ones, up to 5 mm thick, were made on cardboard or round-leaf machines. Large thicknesses were achieved by gluing several sheets together. In order to achieve the smoothness effect, the material was processed by pressing and honing in a friction calender, and then polished with agate stones.
A pusher used as an insulating material in electrical engineering. It was used as a material for folding files and for making brillions. In the textile industry it was used to finish fabrics. Gaskets for water, oil, etc. were made.
