Innovative Film Resins From Dow Offer Differentiation and Processing Advantages
New Products Deliver Better Optics, Improved Toughness and Faster Processing NPE 2009, Chicago - June 22, 2009 The Dow Chemical (“Dow”) today responded to film converters’ need for materials offering better optics, improved toughness and faster processing opportunities by announcing a range of innovative new film resins for use in food and specialty packaging, industrial and consumer packaging, and health and hygiene applications. The new products include developmental DOWLEX™ NG (Next Generation) Linear Low Density Polyethylene (LLDPE) Resins that take LLDPE performance to a new level, new ATTANE™ NG (Next Generation) Ultra Low Density Polyethylene (ULDPE) Resins that allow the use of ULDPE in more demanding applications, and a developmental high-pressure Low Density Polyethylene (LDPE) Resin created to run at faster rates on blown film lines in blends with LLDPE. “Dow is committed to driving innovation across its strong Polyethylene franchise to meet the clear needs of converters in these challenging business conditions,” said Anand Sundaresan, food and specialty packaging market manager for Dow’s Basic Plastics business in North America. “The LLDPE, ULDPE and LDPE products we are announcing today advance a continuous track record of innovation that started in the 1930s and is showing no signs of abatement.” DOWLEX™ NG LLDPE Resins DOWLEX™ NG LLDPE Resins build on the performance credentials of DOWLEX™ Resins by offering greater differentiation opportunities for film converters through better optics and improved downgauging potential with good processability. These breakthroughs are enabled by Dow’s Ziegler-Natta (Z-N) catalyst technology combined with the company’s proprietary Solution Process, which together have delivered ‘super octene’ LLDPE products. Two developmental resins based on this technology are now available: XUS 61530.02 LLDPE¹, ² and XUS 61530.04 LLDPE¹, ². XUS 61530.02 LLDPE offers an excellent combination of dart, tear and puncture balance, as well as outstanding clarity and gloss for a 0.8 MI product. Its excellent melt strength and bubble stability, along with its physical properties, make it suitable for applications such as heavy duty shipping sacks and down-gauged lamination films. XUS 61530.04 LLDPE offers exceptional optics and high-processability without sacrificing physical properties. It has been specifically optimized to deliver clarity in pure component systems or in blends with LDPE, for use in high quality blown film applications where a combination of excellent optics, tear strength and sealability are required, such as high clarity lamination films, stretch hood skins requiring high stretch and optics, agricultural films, medium-performance sealant layers and specialty packaging. Both developmental resins offer substantial downgauging potential, supporting the development of more sustainable packaging using less material. By offering improved protection of end-use products they also have the potential to reduce end-use product damage and waste. ATTANE™ NG Ultra Low Density Polyethylene (ULDPE) Resins ATTANE™ NG Ultra Low Density Polyethylene (ULDPE) Resins are designed with a molecular structure optimized to offer a combination of improved toughness (especially for cold temperature film applications), better optics, excellent flex crack resistance, low seal initiation temperature and enhanced processability. These performance properties make ATTANE NG ULDPE Resins well suited for demanding film applications targeted for use in abusive environments. The first resins to be launched as part of the new product family are ATTANE™ NG 4701G ULDPE and ATTANE™ NG 4703G ULDPE. Both grades offer an excellent balance of modulus, tear, puncture and bubble stability, achieved through Dow’s proprietary Solution Process. More specifically, ATTANE NG 4701G ULDPE is a 0.912 density grade offering unparalleled ULDPE toughness and a 0.8 Melt Index. ATTANE NG 4703G ULDPE is a super tough 0.905 density grade with a 0.5 Melt Index, providing the added benefit of enhanced optics. It is also a good sealant resin by virtue of its low heat seal initiation temperature. This resin, with its excellent impact modification, is well suited for use in heavy duty shipping sacks, as well as in general use cold temperature films, modified atmosphere packaging and individual quick frozen films. Developmental High-Pressure LDPE Dow is demonstrating its continued commitment to the LDPE innovation with XUS 60019.90 LDPE Resin¹, ², a developmental high-pressure LDPE grade specifically created to run at faster rates on blown film lines in blends with LLDPE. The new grade has a molecular structure that is optimized to create excellent synergy within LLDPE blends, offering the potential for truly significant production speeds. The increased output potential can be likened to “finding a hidden line,” enabling converters to debottleneck, maximize capacity potential and possibly avoid capital investments in new product facilities. In Dow tests, XUS 60019.90 LDPE Resin delivered a 15 percent increase in output over competitive LDPEs, and a 25 percent reduction in haze³. Brand owners and retailers will also welcome the great optics its offers, enabling eye-catching shelf appeal. Available Now Samples of all of the new film resins announced by Dow today are available now for evaluation by converters. For more information, please contact a Dow sales or technical services representative or go to www.dowplastics.com. The resins can also been seen running on processing equipment at NPE (Chicago, June 22-26). Sources:
