REINACH, US: Archroma announced the introduction of a new optical brightening agent (OBA) specially designed for food packaging and paper, Leucophor® AFCN liq. The newly launched OBA has been approved for food contact by the US food and drug administration.

A growing part of food containers are made from renewable sources, such as paper and board. It is necessary to ensure that these paper containers are free from substances that would be harmful for the consumer.

Leucophor® AFCN liq was designed with these guiding principles:

  • Leucophor® AFCN liquid has approval for use in food-contact paper and paperboard under FDA Food Contact Notification.
  • It is ideally suited for stock application and for use in coating formulations that contain polyvinyl alcohol (PVOH), carboxymethyl cellulose (CMC) or casein as a secondary binder.
  • It is a disulphonated OBA, with a characteristically high substantivity in the wet-end delivering the papermaker cost savings through the ability to make more rapid grade changes.

“The liquid provides our customers with greater flexibility to produce attractive, white, paper-based packaging and containers for food applications,” said Andrew Jackson, global product manager OBA, Archroma.
