New light-blocking additive technology for Dairy Products

Avient Corporation, a premier provider of specialized and sustainable material solutions and services, announced new light-blocking additive technology for PET dairy packaging, enhancing its existing ColorMatrix Lactra light-blocking additive concentrates

Comply EU standard

This different additive technology helps customers’ packaging products to comply with new titanium dioxide (TiO2) constraints in Europe under the EU Waste Framework Directive 2008/98/EC.

Helps in recycling

In past years, white opaque PET bottles for dairy applications have been under increasing scrutiny for their mineral fillers’ potential effects on the recycle stream used to create the fiber. 

Great potential for light blocking in monolayer PET

This latest Lectra technology offered brand owners and PET packaging converted the ability to achieve over 99.9% light blocking in monolayer PET, with high whiteness (L* of up to 94) but less than one weight percent TiO2 and less than four weight percent inorganic content. This technology is also available in TiO2 in a free variant. 

FDA approval for food contact

Finished with food contact approvals for the European Union and FDA, this new Lactra additive is agreeable with the PET recycling stream for fibers, sheets, and strapping. Testing also explains that in established opaque white PET recycle streams, Lactra products are fit for closed-loop bottle-to-bottle recycling. 
Commercially available in major sectors worldwide, new Lactra light-blocking additive technology from Avient can help customers facing TiO2 limitations comply with guidance without compromising performance.
