  • Patent number: 10626271
    Abstract: An essentially biobased and optionally biodegradable, thermoformable composition containing a) as thermoformable resin at least one poly-L-lactide with less than 1 mol % of D-lactoyl units (PLLA) or at least one poly-L-lactide with 1-5 mol % of D-lactoyl units (PLA) and b) a nucleating combination of ?) 1 to 10% Wt. of at least one poly-D-lactide with less than 1 mol % of L-lactoyl-units (PDLA) or of 0.5 to 5% Wt. of PLLA/PDLA or PLA/PDLA stereocomplex crystallites, ?) 0.1 to 25% Wt. of an inorganic nucleating agent, and ?) 0.1 to 30% Wt. of at least an inorganic filler with lamellar structure, and thermoformed, essentially biobased and optionally biodegradable containers formed of the inventive compositions.

  • Patent number: 8203008
    Abstract: The present invention is directed to stable lactide particles, more specifically lactide particles which are stable enough to be stored and transported at room temperature and have a quality high enough for use as starting material for polylactic acid. The lactide particles have a surface/volume ratio of the particle is lower than 3000. Preferably the lactide in the particle has an optical purity of at least 95%. The lactide particles are prepared by subjecting lactide to a shaping step comprising extrusion, pastillation, prilling, tabletting, or flaking.

  • Patent number: 8097736
    Abstract: The present invention is directed to a method for the manufacture of stable lactide particles, more specifically lactide particles which are stable enough to be stored and transported at room temperature and have a quality high enough for use as starting material for polylactic acid. The lactide particles are obtained via a flaking process, comprising the contacting of a continuous flow of molten lactide with a surface on which the lactide solidifies and subsequently is removed from said surface.
