More versatility in food packaging

AddivantTM next generation Weston® 705 earns FDA approval for food contact applications

AddivantTM, a global leader in polymer additive technologies, announced that Weston® 705 liquid antioxidant, the next generation of nonylphenol- free phosphite technology, had received approval from the U.S. Food and Drug Administration (FDA) for food contact applications.

Extensively researched and supported with comprehensive toxicology testing, Weston® 705 antioxidant provides superior safety as well as enhanced polymer performance and higher processing productivity vs. conventional solid phosphites. The product delivers major benefits across the entire value chain, from resin producers and converters to retailers and consumers. It is produced in multiple facilities worldwide, ensuring security of supply for customers around the globe.


Weston® 705 antioxidant is a highly effective stabiliser that protects polymers from degradation during use. It represents the newest generation of liquid phosphite technology, the preferred secondary antioxidant for linear low density polyethylene (LLDPE) and high density polyethylene (HDPE) polymers. This product looks, handles and functions like Weston® TNPP phosphite but is nonylphenol free and higher in phosphorous, so lower loadings (up to 18% lower) provide equivalent performance.

With FDA approval for food contact applications, Weston® 705 antioxidant now offers greater versatility, enabling its use in a wide range of food packaging, from deli wrap to snack food bags and from carton liners to boil-in bags, as well as non-food packaging and non-packaging applications. Weston® 705 antioxidant – a clear, colorless, odorless liquid – also supports major conversion trends such as multilayer films and coated, laminated films. Peter Smith, President and CEO, Addivant, said: “We developed our innovative Weston® 705 liquid antioxidant with the future in mind. Not only does this technology overcome the drawbacks of conventional solid phosphites, it also enables our customers to capitalise on their latent technology to further enhance the polymer architecture allowing them to meet the needs of the very latest in processing systems, end markets and applications. Our proactive investment in gaining comprehensive global food- contact approvals for Weston® 705 antioxidant, together with our robust supply chain of regional manufacturing facilities helps Addivant support its mission of winning with our customers.”




Addivant’s Weston® 705 antioxidant delivers important improvements in safety, performance and productivity compared to existing phosphite antioxidants, benefiting each link in the value chain.



With comprehensive global food approvals and nonylphenol-free formulation, Weston® 705 antioxidant helps boost
consumer confidence about the safety and sustainability of food packaging.




Advancements in Weston® 705 antioxidant’s stability performance pave the way for new polymers that deliver improved color and surface aesthetics and better film quality. This technology meets the demands of new engineered plastics solutions where polymers must withstand rigorous processing conditions such as higher temperatures, greater shear and increased recycling. Its superior stabilization performance delivers a 10-fold improvement in color protection vs. standard antioxidants, and also enables thinner film with the same strength.



As a liquid, Weston® 705 antioxidant provides better phosphite solubility than solid products, helping to reduce downtime for die cleaning and enabling processors to run production lines faster without concerns about polymer degradation. Low gel formation (one-fourth the gels of standard antioxidants) also contributes to improved productivity.
