TotalEnergies Corbion Unveils Compostable PLA Foam to Replace Polystyrene Packaging
TotalEnergies Corbion has introduced Luminy FOAM 50F, a new high melt strength polylactic acid (PLA) grade designed as a sustainable alternative to extruded polystyrene (XPS) foam used in food packaging. The bio-based material is engineered for extrusion foaming applications, offering packaging manufacturers a compostable, lower-carbon solution without requiring major changes to existing production lines.
The new PLA grade is specifically developed for fresh food packaging, including meat and seafood trays, as well as foodservice products such as clamshell containers and bowls. According to the company, Luminy FOAM 50F delivers performance comparable to conventional XPS while helping brands transition to more environmentally responsible packaging materials.
As governments around the world tighten regulations on polystyrene in food-contact applications, demand is increasing for scalable alternatives that combine sustainability with industrial efficiency. TotalEnergies Corbion says Luminy FOAM 50F is designed as a drop-in replacement for polystyrene, allowing converters to process the material on existing XPS extrusion lines with similar production speeds and only minimal equipment modifications.
Laurent Daligault, Global Packaging Segment Leader at TotalEnergies Corbion, said the product is among the first industrial-scale solutions developed specifically to replace polystyrene foam rather than serving as a niche alternative. He added that the sugarcane-based PLA can reduce the carbon footprint of foam packaging by at least 70% compared with conventional XPS, while maintaining processing performance and functionality.
Luminy FOAM 50F combines several sustainability advantages in a single material. It is bio-based, industrially compostable, recyclable, and free from styrene, PFAS, and persistent microplastics. The company says these features address growing environmental concerns while meeting the performance expectations of food packaging manufacturers.
The material’s high melt strength enables stable foam production without requiring additional chain extenders, reactive processing, or other performance-enhancing additives. It also produces low-density foam with a uniform cell structure, making it suitable for demanding packaging applications such as fresh protein trays.
Hao Ding, Global Marketing Director at TotalEnergies Corbion, said the launch reflects the company’s commitment to developing high-performance materials that support both sustainability goals and customer needs.
Luminy FOAM 50F is now available for commercial orders worldwide. The material has received FDA and Korean Food Contact approvals for food packaging applications in markets that follow these regulatory standards. In other regions, it can currently be used for non-food applications, with the company offering technical support to help customers implement the new material.
