Archroma recently 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.
Urbanisation and digitalisation are rapidly changing our lifestyle. People around the globe are increasingly purchasing and consuming on the go. 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, opines the firm.
The company is committed to continuously challenge the status quo in the deep belief that it can make its industry sustainable. The firm strives to introduce innovations that allow safe, efficient and enhanced manufacturing processes and end products, adds the company.
The Leucophor AFCN liquid was designed with the following guiding principles in mind:
• Has approval for use in food-contact paper and paperboard under FDA Food Contact Notification 1921, which became effective on November 9, 2018.
• 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 company states that there is a fast-growing demand for food packaging made with paper and board, and their new OBA has been developed to help manufacturers to respond to that demand.
