Avient Corporation Launches Light-blocking Additive for Dairy PET Packaging

This new technology from Avient is suitable for use in packaging for products such as ultra-high temperature (UHT) liquid dairy containers, which have longer shelf-life requirements and are often stored in ambient conditions.

Lactra™ LX additive also offers the advantage of versatility in container designs and shapes, allowing for product differentiation over other rigid packaging solutions and enhancing consumer convenience with easy-to-pour options. Additionally, it provides the opportunity for lightweighting, reducing overall cost without sacrificing performance.

'Light blocking has been traditionally achieved by using multilayer high-density polyethylene (HDPE) and PET packaging,' said Felipe Reichert, global marketing director for Color, Additives & Inks at Avient Corporation.

'Our Lactra™ LX additive enables blocking of 100% of visible light in monolayer PET containers, protecting and preserving the quality of dairy products and helping to extend shelf life while delivering a bright white color as a solid masterbatch.'

Initially introduced in Europe as ColorMatrix™ Lactra™ SX, the new bright white Lactra™ LX technology is primarily available in North America.
