Three companies recently introduced new colorants and modifiers for bioplastics:
- 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.
- PolyOne Corp., Cleveland, introduced OnCap Bio Impact T, an impact modifier
for PLA that also maintains transparency. It is said to make toughened products easier to cut and hole-punch; it reduces scrap from product breakage; and less breakage means fewer sharp edges to injure workers. It is offered as a solid or liquid concentrate and meets U.S. and EU food-contact specs.
- Teknor Color Co., Pawtucket, R.I., offers fully bio-based, compostable color concentrates for PLA, two types of PHAs—PHBV and PHB (Mirel from Telles)—and PBAT, a petrochemical-based but fully biodegradable polyester.

In failure analysis, there is a tendency to gravitate to a few common test protocols. But this approach can result in a mismatch of techniques to the problem.
