Danbury, Connecticut (January 26, 2016) -  Addivant™ announced a multi-million dollar expansion program at the company’s Morgantown, WV manufacturing facility to meet increasing demands for WESTON® 705. WESTON® 705 is a nonylphenol-free antioxidant developed for use in polyethylene manufacturing that has received extensive regulatory approvals for use in food packaging applications. This expansion will more than triple Addivant’s capacity for production of the liquid phosphite antioxidant, enabling manufacturers of polyethylene films and rigid formats to meet food packaging needs without using nonylphenol chemistry.

John Steitz, Addivant’s President & CEO, stated “Addivant™ is committed to providing the food packaging industry with rigorously tested antioxidants for use in food packaging that delivers important improvements in performance, safety, productivity and ultimately benefits each link of the supply chain.   We will continue to make strategic investments in our operations around the globe to support the growing market demand for WESTON® 705.”

Phosphite antioxidants are necessary ingredients in packaging films and, while used in extremely low concentrations, need to be thoroughly tested because films come in direct contact with food products. WESTON® 705 was specifically designed as a solution to reduce the need to use nonyphenol-based AO in food packaging while also complying with the strict, and often complex, global regulatory requirements without compromising on packaging film clarity, color or processing performance.

Interest in polyethylene film with WESTON® 705-inside™ has grown significantly as consumers demand greater transparency into  understanding more about the chemical composition of the packaging that touches their foods – particularly organic and natural food products.  Addivant’s WESTON® 705 antioxidant meets that demand.
