Paper

What is paper?

Paper is an essential material in everyday life and industry: it serves as an information medium, packaging material, construction base or design surface. Technically, paper consists of a network of plant fibres – mostly wood – bonded together through water, pressure and drying.

The exact composition, manufacturing process and additives determine which paper properties emerge – such as tear resistance, printing behaviour, moisture resistance or tactile feel.

Today, there is an enormous variety of paper grades – from classic offset or recycled papers to functional speciality papers specifically developed for industrial, decorative or technical applications.

How is paper produced – from fibre to material

Paper production begins with the fibre material, which is mainly obtained from wood. Three main sources are used:

• Pulp (from fresh wood, chemically processed)
• Groundwood (mechanically defibrated wood)
• Recycled fibres (from waste paper)

These fibres are mixed with water, fillers (e.g. kaolin, chalk) and additional additives – depending on the desired properties of the finished paper. In the paper machine, this fibre–water mixture forms an endless web that is drained, pressed and dried over screens.

Many paper properties can already be controlled during production – for example through:

• Sizing for improved moisture resistance
• Calendering or embossing to adjust surface texture
• Pigmentation or coating for printability or barrier performance

The entire process – from stock preparation to finished reels or sheets – enables finely controlled material quality tailored to the intended application. This makes paper a highly adaptable material – far beyond traditional printing uses.

What types of paper exist – and where are they used?

Paper is not just paper: depending on composition, processing and finishing, very different paper types with specific properties emerge. They can be broadly divided into three main categories:

1. Graphic papers

These classic printing papers are used for books, magazines, catalogues or marketing materials. They are characterised by good printability, uniform surfaces and defined opacity. These include:

• Offset papers
• Coated art papers
• Newsprint papers

2. Packaging papers

These papers provide stability, volume or barrier functions – for example against grease, moisture or light. They are used in cartons, carrier bags, pouches or labels and may be laminated, coated or impregnated.

3. Technical and speciality papers

This category includes paper types developed for functional, industrial or decorative applications – often as alternatives to films, textiles or composite materials. These include:

• Carrier materials for coatings or adhesives
• Wallcoverings and decorative papers
• Papers with security features
• Heat‑resistant, weatherproof or tear‑resistant papers

Especially in the speciality paper sector, the full potential of the material becomes clear: through targeted combinations of fibres, additives and surface technologies, customised solutions are created – for industries ranging from architecture and design to electronics and construction.

Which properties make paper so versatile?

Paper stands out for its exceptional material diversity. Depending on fibre composition, processing and surface treatment, specific properties can be generated – relevant for applications ranging from simple writing paper to highly functional carrier materials.

Key paper properties include:

• Printability: Paper can be processed with almost all printing technologies – offset, digital or screen printing. Absorbency, smoothness and pigmentation strongly influence print quality.
• Strength: Tensile, tear or wet strength play important roles, especially for packaging papers, labels or security applications.
• Surface structure: Smooth, matt, glossy or embossed – finishing processes allow both visual and tactile effects.
• Moisture behaviour: Through sizing or special impregnation, paper can be made water‑repellent or even moisture‑resistant.
• Processing behaviour: Good flatness, dimensional stability or fold performance support industrial processing – in printing, cutting or laminating systems.

This diversity makes paper a modern, flexible material that is both functional and aesthetic – and able to adapt to various industry requirements.

Paper at LAHNPAPER – specialised solutions for industry & design

At LAHNPAPER, paper is not only used for traditional printing applications, but as a technical material tailored to demanding requirements. The company develops high‑quality speciality papers and non‑wovens that go far beyond conventional information carriers.

Typical applications include:
