* Arkema Inc., Philadelphia, has found that its Biostrength 700 melt-strength enhancer enables faster string-up. a wider processing window, and more consistent thickness in blown films and extrusion coatings of polylactic acid (PLA). Previously, the additive had been used in PLA calendering, injection molding, and other types of extrusion.
