CESA™ ProTect

CESA™ ProTect by Avient is an oxygen scavenger additive masterbatch for polyester packaging. Provides unmatched shelf-life extension for packaged food and beverages. It combines enhanced food protection with sustainable packaging design. It is highly compatible with polyethylene terephthalate (PET) and does not appear to impact processing. The active ingredients in CESA® ProTect masterbatch absorbs oxygen molecules as they enter so they cannot reach the protected product and can maintain the oxygen level inside the packaging at well below 1 ppm for an extensive number of months. It is active only after processing. It is also suitable for cold chain distribution as it has performed well when used on refrigerated products. CESA™ ProTect has only a limited effect on mechanical and optical properties of the product and can be used for transparent as well as colored packaging articles.
