Form the future with Airlaid

ANDRITZ airlaid technology opens the world to various products from the broad range of disposable products

ANDRITZ offers complete airlaid production lines and stand-alone airlaid webforming units, defibration technology, flat bed dryer technology, and fiber recycling processes.

THE PROCESS

  • The airlaid technology can perfectly process short fibers.
  • These are fed into a forming head by an airstream.
  • The forming head ensures a homogeneous mix of all fibers. 
  • Using air once again, a controlled part of the fiber mix leaves the forming head and is deposited on a moving belt, where randomly oriented web is formed.
  • Powders, for instance SAP, can be homogeneously added to the web

Mill to web units are also part of the portfolio for the production of dry molded packaging materials based on pulp. ANDRITZ Dan-Web, as the central competence unit for airlaid-based products, has outstanding expertise in the processing of wood pulp as a base material. This improves the sustainability effect by using biodegradable and environmentally friendly fiber material.

The airlaid production process produces materials that are used in food pads, technical wipes, biodegradable wipes, baby, fem and adult care products, dry molded pulp packaging, napkins, table cloths and many more.
