DiamondClear®
|
the industry’s most advanced oxygen scavenging technology available for PET containers. A sustainable alternative to glass and multi-layer plastic containers, DiamondClear offers food and beverage products many advantages, including barrier protection for up to 24 months, the clarity and gloss of glass, enhanced sustainability, and 100 percent recyclability. Barrier Technologies
Constar has developed a suite of proprietary industry-leading PET technologies tailored to the specific oxygen barrier needs of our customers. Constar continues to invest heavily in significant monolayer barrier material development. Our technologies employ sophisticated oxygen scavengers blended evenly throughout the PET, resulting in rigid containers with superior barrier performance and a more robust construction than multi-layer plastic packages that are prone to delamination.
Constar’s PET barrier technologies protect sensitive food and beverage products from degradation induced by oxygen ingress, loss of carbonation or light strike. They extend the shelf life of products such as beer, juices, teas, enhanced waters, wine, flavored alcoholic beverages, and ketchup and other food products.
