Nucleating agent approved for PE food packaging.A "hyper-nucleating" agent designed for polyethylene blown film was recently granted broad food-contact approval by the FDA FDAabbr. Food and Drug Administration FDA, n.pr See Food and Drug Administration. FDA, n.pr the abbreviation for the Food and Drug Administration. . Launched a year ago by Milliken Chemical, Spartanburg, S.C., Hyperform HPN-20E reportedly cuts haze by 40% in LLDPE LLDPE Linear Low Density Polyethylene and increases gloss by 100%. It is said to be a simpler, better alternative to blending with LDPE LDPE abbr. low-density polyethylene because it enhances optics without sacrificing 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 nu·cle·a·tion n. 1. The beginning of chemical or physical changes at discrete points in a system, such as the formation of crystals in a liquid. 2. The formation of cell nuclei. to achieve cycle-time reductions in blow molding HDPE.TeI: (800) 345-0372 * www. millikenchemical.com [ILLUSTRATION OMITTED] |
