Archroma unveils OBA for food packaging

 

Archroma recently introduced a new optical brightening agent (OBA) specially designed for food packaging and paper, Leucophor® AFCN liq. The OBA has been approved for food contact by the US Food and Drug Administration.

 

Leucophor® AFCN liquid has approval for use in food-contact paper and paperboard under FDA Food Contact Notification 1921, which became effective on 9 November 2018. Leucophor® AFCN liquid 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. Leucophor® AFCN liq 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.

 

With fast growing demand for board and paper packaging, Leucophor® AFCN liquid OBA has been developed to help manufacturers to respond to that demand, according to Andrew Jackson, Global Product Manager Optical Brightening Agents, Paper Solutions Business, Archroma. The latest OBA complements Archroma's FDA-compliant tetrasulphonated OBAs and shading colorants to give customers with greater flexibility to produce attractive, white, paper-based packaging and containers for food applications.
