Filtrona PLC LSE: FLTR is a supplier of plastic and fibre products. The company operates internationally from headquarters in Milton Keynes in the UK. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The Company was established in Jarrow in the 1940s as the Fibres division of Bunzl. In 1955 it acquired Moss Plastics, a plastic products manufacturer, in 1994 MSI Oilfield Products, a pipe protection business, and in 1996 it bought Payne, a manufacturer of self-adhesive tapes.

In 1997 the Bunzl Fibres division bought Filtrona Corporation, a US filter technology specialist which it had demerged in 1984. At this time the Filtrona name was adopted for the enlarged Bunzl Fibres business.

Filtrona bought Enitor, a Dutch extruder business, in 1998 and Skiffy Group, a Dutch nylon parts business in 2004. Filtrona was demerged from Bunzl in 2005. It went on to buy Duraco, a US adhesive coated products business in 2007. In 2008, Filtrona purchased Lendell Manufacturing, a foam manufacturer. The foam and fiber businesses were combined into a new division and named Filtrona Porous Technologies.
