DuPont Packaging offers DuPont Biomax Strong, an additive that improves the performance of bio-based, biodegradable polylactic acid (PLA) packaging. Biomax Strong, a petrochemical additive that improves the toughness and reduces the brittleness of PLA materials,  enhances the impact strength, flexibility and melt stability of PLA, particularly when used in rigid applications such as cast sheets for thermoforming and injection molding.  
    
When used at the recommended levels (between one to five percent of weight), Biomax Strong outperforms competing products with improved toughness and minimal impact on transparency. Biomax Strong, at the recommended amounts, allows the material to still meet the compost ability requirements.Two grades are available:  Biomax Strong 100 for use where no regulatory food compliance is necessary and Biomax Strong 120 which  complies with food contact regulatory requirements.
