TotalEnergies Corbion Launches Luminy FOAM 50F: Low-Carbon PLA Alternative to Polystyrene
GORINCHEM, Netherlands — TotalEnergies Corbion today announced the commercial launch of Luminy® FOAM 50F, a high melt strength PLA grade designed for extrusion foamed packaging applications. Developed for trays used in fresh food products like meat and fish, and food service packaging such as clamshells and bowls, the material delivers the performance of conventional extruded polystyrene (XPS) while providing a lower-carbon, circular alternative.
As packaging producers face increasing regulatory pressure to phase out polystyrene in food applications — with restrictions expanding globally — the market is actively seeking alternatives that combine environmental benefits with industrial scalability. Luminy FOAM 50F addresses this need with a bio-based, industrially compostable material that enables a practical transition without disrupting established production processes.
Drop-in Replacement for XPS
Luminy FOAM 50F is engineered as a drop-in replacement for polystyrene, allowing converters to run it on existing XPS extrusion lines with comparable throughput and minimal modification. The material’s high melt strength enables stable foam production without the need for extra additives, chain extenders, or reactive processing.
“With polystyrene bans accelerating, this is one of the first solutions positioned as a true industrial-scale replacement, not a niche material,” said Laurent Daligault, Global Packaging Segment Leader at TotalEnergies Corbion. “Luminy FOAM 50F enables converters and brand owners to adopt a truly sustainable drop-in solution to XPS, both in terms of processing and product functionality. It is also good for our planet, with our sugarcane-based PLA delivering at least a 70% reduction in carbon footprint compared to XPS foam parts.”
Technical Advantages
The material combines performance and sustainability characteristics that have historically been difficult to achieve in XPLA foam packaging:
- Comparable density and functional properties to XPS while maintaining processing efficiency on standard equipment
- Bio-based, industrially compostable, recyclable — free from styrene, PFAS, and persistent microplastics
- High melt strength enables stable foam production without additives or chain extenders
- Uniform cell morphology for demanding applications like fresh protein packaging
- FDA and Korean Food Contact approved for food applications; non-food applications in other regions
Market Context
Global polystyrene bans are accelerating across jurisdictions. The EU Single-Use Plastics Directive restricts certain polystyrene food containers, while multiple US states and Canadian provinces have enacted or proposed similar measures. TotalEnergies Corbion’s launch timing aligns with converters’ urgent need for qualified alternatives.
The company provides technical support to assist customers with implementation, and Luminy FOAM 50F is available for commercial orders globally.
