PARALOID™ BPM-500 maintains clarity while strengthening bioplastics

Wednesday 25 July 2007

Rohm and Haas improves the performance of green packaging with the launch of their new additive, PARALOID™ BPM-500, an impact modifier that broadens the usability of bioplastics by making them stronger without sacrificing clarity. PARALOID™ BPM-500 supports the packaging industry’s movement toward sustainability by enhancing polylactic acid (PLA) polymer, an innovative bioplastic derived from a renewable resource, such as corn, and used in some packaging applications.

The packaging industry’s move toward PLA resin has been hampered by unmodified PLA being somewhat weaker and more brittle than traditional materials. Previous attempts to strengthen PLA packaging have sacrificed transparency in their efforts. Rohm and Haas’ new PLA additive, PARALOID™ BPM-500, toughens PLA packaging while maintaining clarity, thereby fulfilling a key industry need.
