“PET is already a good barrier material,” notes Antonello Decortes, Global Product Manager at Clariant, “but sensitive applications may still suffer from oxygen inlet. This is not a problem for water or most carbonated soft drinks, but fruit juices lose vitamin potency and undergo a color shift, dairy products can sour, coffee capsules suffer flavor loss, and as little as 1 ppm of oxygen can change the taste and odor of beer. CESA ProTect additives can help extend the shelf life of these products and ensure that less food is thrown away.”
“Based on these test results,” says to Alessandro Dulli, Global Head of Segment and Business Development, Packaging, “we believe that CESA ProTect is one of the most powerful oxygen-scavenging masterbatch on the market.”
