DuPont™ Biomax Strong ® How to improve the performance of PLA packaging… Bio-based and compostable packaging just got better! Biomax® Strong*, an additive that improves the performance of bio-based and compostable polylactic acid (PLA) packaging, improves toughness and reduces brittleness — without sacrificing product clarity! …and still maintain environmental-friendliness ! DuPont™ Biomax® Strong reduces PLA brittleness with as low as 2% wt addition. Splitting, cutting and slitting performance, and bending cast sheets improve significantly with just a small %-addition of Biomax® Strong. Add Biomax® Strong modifier to your material composition… Biomax® Strong is an ethylene copolymer designed to modify PLA and enhance its performance in packaging and industrial applications. Biomax® Strong Benefits • Increases Toughness • Improves Viscosity Stability • Reduces Brittleness • Improves Machineability and Cutting • Enhances Flexibility • Shows Good Contact Clarity • Improves Impact Strength Available in the following grade: Biomax® Strong 120 — For food packaging applications *Patent Pending

DuPont™ Biomax® Strong improves Impact Strength/ Toughness and Flexibility When repeatedly flexed, cast sheets modified with Biomax® Strong will withstand a significantly higher number of flex cycles. Elongation at break is significantly increased with increased Biomax Strong content up to a maximum that is reached at around 5–10 wt% addition rate. ® Elongation at Break, % (Tensile test at 2.5 cm/m) Elongation at Break (%) (tesnile test at 2.5 cm/m) 0 0 % Biomax® Strong 100 in PLA (Amorphous cast sheet) Amount Biomax® Strong 100 in PLA3001D DuPont Biomax Strong Improves Process Conditions of...
