Metabolix polyhydroxyalkanoates (PHAs)-based biopolymer technology enables
manufacturers and brand owners across the plastics and packaging industries to
meet sustainability and performance objectives. Information on the Company's
products will be available at the show or at

  oMvera™ B5011: This certified compostable film grade resin from Metabolix
    is designed as a transparent option for the compostable film and bag
    market. Mvera B5011 provides excellent clarity and low haze, as well as
    performance characteristics such as tear and puncture toughness, excellent
    seal strength, and a balance of strength and stiffness. Mvera B5011
    combines easy processability with certified compostability to deliver
    unique advantages for packaging applications.
  oMvera™ B5010: This film grade resin from Metabolix is designed for
    compostable bag and film markets across the globe. It meets international
    industrial standards for compostability and has been certified by Vincotte
    to meet the EN13432 standard. The resulting film has exceptional seal
    strength and good printability, making it an ideal option for compostable
  oPerformance Additives: Metabolix has developed a line of PHA biopolymer
    performance additives for traditional and biobased plastics, including PVC
    (polyvinyl chloride) and PLA (polylactic acid). In packaging applications,
    Metabolix's performance additives can be used as property modifiers to
    impart a range of physical and performance properties in PVC and PLA.
  oColor Masterbatches: Metabolix biopolymer color masterbatches are highly
    compatible with a wide range of biopolymers, and can preserve high
    bio-content and certifiable compostability for broad end-of-life options,
    including soil and marine degradability and suitability for home compost.
    Metabolix will display its color masterbatches based on PHA in cooperation
    with AF-Color.
  oMetabolix Developmental Grades in Film and PHA Latex Coatings: Metabolix
    will be featuring developmental film grades that enable creation of film
    products with a range of properties and capabilities. For example,
    Metabolix will display films that can range from flexible to stiff while
    maintaining high load carrying capabilities. Metabolix's PHA biopolymers
    also provide the benefit of biocontent, toughening, and flexibilization to
    film compounds used in packaging applications.
  oMetabolix also is developing PHA latex coatings for packaging
    applications.These PHA latex coatings are expected to offer good barrier
    properties and tough, tack-free performance. Metabolix's PHA patex
    coatings are biodegradable in marine and soil environments, as well as by
    anerobic digestion, while maintaining compatibility with repulping, the
    most common recycling method used for paper and cardboard.
