Dairy Contents Protection With Superior Whiteness & Low Inorganic Content With TiO₂ content between 4% and 0%, ColorMatrix™ Lactra™ Four, One and Zero offers light blocking up to 99.9%, improved performance in thin wall sections, superior whiteness, and can be processed with standard PET grades and rPET. Brighter whiteness L* >90 even in thin wall sections (0.21mm)

In recent years, white opaque PET bottles for dairy applications have been under increasing scrutiny for the potential effects their mineral fillers can have on the recycle stream used to create fiber. This latest Lactra technology offers brand owners and PET packaging converters the ability to achieve over 99.9 percent light blocking in monolayer PET, with high levels of whiteness (L* of up to 94) but with less than 1 weight percent TiO2 and less than 4 weight percent inorganic content. Testing also shows that in established opaque white PET recycle streams, Lactra products are suitable for closed loop bottle-to-bottle recycling.

Cesa™ bright masterbatches convert UV radiation into visible, bluish light in order to improve the long-term, white appearance of finished plastic products. Topical optical brighteners have been used to improve the surface whiteness of plastic articles and synthetic fibers.

Purging If the press is idle for more than 10 minutes, purge thoroughly with a low flow (0.5-2.5 melt flow) polyethylene (PE) or polypropylene (PP) before restarting component production.
