What is airlaid?

Airlaid is a type of nonwoven material in which air rather than water is used during the forming process.

It is a textile-like material made from natural wood fibres, also known as cellulose pulp. The fibres are bonded using mechanical, chemical or thermal processes to form a nonwoven material.

Airlaid is produced through a web-forming process known as “airlaying”, in which short, randomly oriented fibres are dispersed in an air stream to create a uniform mixture, which is then deposited onto a moving air-permeable belt or forming surface.

It can be produced using different techniques and technologies: through thermal bonding, using latex as a binder, under specific temperature, pressure and humidity conditions to create hydrogen bonds, or by combining different bonding methods.

Its physical properties include resilience, softness, liquid absorption capacity and liquid retention.

Unlike conventional wet-forming processes, where water is used to form the material, the airlaid process uses an air stream to transport and distribute the fibres. The material is therefore formed without the use of water during this stage of the process.

Thanks to its strength and absorption capacity, airlaid is used in a wide range of everyday products, including diapers and feminine hygiene products, medical products, food packaging, industrial cleaning materials, tablecloths and napkins, wipes and other applications.

Airlaid has specific characteristics that distinguish it from other nonwoven materials.

STRENGTH: it maintains good strength even when wet.

ABSORBENCY: it can achieve high absorption capacities depending on the structure and composition of the material.

HYGIENE APPLICATIONS: it is widely used in the manufacture of hygiene products.

COMPOSITION: it can be produced using long-fibre cellulose pulp.

Magic develops different types of airlaid for applications requiring specific absorption performance. These include Airgel  and Airgel g-grade, which incorporate Spongel as their superabsorbent component and whose structure does not use thermoplastic fibres.

In the configurations covered by the relevant certificate, Spongel and Airgel g-grade are OK Compost Industrial certified by TÜV Austria for industrial composting.
