A "hyper-nucleating" agent designed for polyethylene blown film was recently granted broad food-contact approval by the FDA. Launched a year ago by Milliken Chemical, Spartanburg, S.C., Hyperform HPN-20E reportedly cuts haze by 40% in LLDPE and increases gloss by 100%. It is said to be a simpler, better alternative to blending with LDPE because it enhances optics without sacrifi cing tear and impact strength. HPN-20E reportedly also can enhance the moisture barrier of HDPE and LLDPE. Trials have shown 40% lower moisture transmission in LLDPE. Milliken has installed a new monolayer blown film line at its applications lab. The company also wants to investigate use of nucleation to achieve cycle-time reductions in blow molding HDPE.Tel: (800) 345-0372 . www. millikenchemical.com
