TotalEnergies Corbion has unveiled Luminy® FOAM 50F, a specialized high melt strength PLA grade aimed at providing a lower-carbon substitute for polystyrene in extrusion foaming applications, particularly for food packaging. This innovative material can be seamlessly integrated into existing XPS extrusion lines, enabling manufacturers to transition without incurring substantial capital costs.
As regulations are increasingly restricting the use of foam polystyrene packaging across various regions, there is a growing need for alternative materials that satisfy both performance metrics and environmental standards. Products made with Luminy® FOAM 50F exhibit densities and functional capabilities that closely match those of XPS, while achieving a remarkable 70% decrease in carbon footprint. Its applications encompass trays for fresh produce, meat, fish, and diverse food service packaging.
This sustainable, biobased material is not only industrially compostable and recyclable but is also free from harmful substances such as styrene, PFAS, and persistent microplastics. Its enhanced melt strength ensures stable foam processing without necessitating additional additives or chain extenders.
“With the rapid implementation of polystyrene bans, we believe this solution represents a significant advancement, serving as an industrial-scale replacement rather than a specialized option,” remarked Laurent Daligault, Global Packaging Segment Leader. “Luminy® FOAM 50F allows manufacturers and brands to utilize a genuinely sustainable drop-in option for XPS that meets both processing needs and product performance expectations. The sugarcane-derived PLA we use results in at least a 70% reduction in carbon emissions compared to traditional XPS foam products. We are eager to assist our clients around the globe in achieving their sustainability goals, both commercially and technologically.”
The material has received FDA and Korean Food Contact approval, making it suitable for food-contact applications in the United States and countries adhering to similar regulations. It is also available for non-food uses in other global markets.
