US-based Addivant announced that its nonylphenol-free stabilizer, Weston 705, has witnessed a broadened commercial use in new generation of linear low-density polyethylene (LLDPE) applications in food packaging.
The use is expected to bring a new level of safety in food packaging across the US, Europem and Asia.
Approved by around 20 major polymer manufacturers, the Weston 705 is claimed to be the only liquid antioxidant for polyethylene producers providing a broadly-tested single-additive solution for global converters and packaging manufacturers.
The US FDA, Europe’s EFSA and China’s NHFPC have approved Weston 705 for use in food contact applications.
According to Addivant, the non-governmental organizations and authorities worldwide are setting new food packaging regulations with a focus on non-intentionally added substances (NIAS).
Weston 705, which is currently available for food-contact use in around 50 countries, will enable polyolefin, elastomer, and PVC producers to expect changing regulations for nonylphenol and other NIAS.
Addivant chief technology officer Dr Jonathan Hill said: “Due to its high phosphorous content, Weston 705 reduces the use of antioxidants by up to 20%, allowing for more flexibility in formulations and recycling.
“Polyethylene resins based on Weston 705 are easier to process, more versatile, and create less plateout or gels than resins based on conventional solid phosphite antioxidant.”
Addivant CEO John Steitz said: “This is another important milestone for Addivant's more than $30 million investments in technology and capacity for Weston 705.”
Based in Connecticut, Addivant produces specialty additives such as antioxidants, light stabilizers, rubber additives, polymer modifiers, metal deactivators, polymerization inhibitors, and intermediates.
The company is an independent portfolio company of SK Capital with 11 manufacturing facilities on five continents.
