Sustainable PLA Packaging Gets a Performance Boost from DuPont™ Biomax®
Thermoformed trays made from polylactic acid (PLA) are modified to improve toughness.
Adding 2-3% DuPont™ Biomax® resin raises PLA performance to practical application levels.
To overcome this, Canadian packaging supplier Tilton Plastics turned to scientists from Natureworks (their PLA supplier) and DuPont to test available PLA toughening methods. An answer was found in specially-developed DuPont™ Biomax® modifier resins, designed for melt-blending with PLA to give it better thermoforming, trimming and handling strength, without significantly reducing natural PLA clarity levels. Resulting “Biogo” trays now are available in many forms, typically replacing styrofoam and PET alternatives.
