Dow Chemical Co., Midland, Mich., has adopted nanolayer technology developed for blown film (the film technology was discussed in our June issue). At the recent SPE ANTEC in Boston, a paper by Dow’s S. Crabree, J. Dooley, J. Robacki, P.C. Lee, R. Wrisley, and C. Pavlicek detailed technology that used feedblock and flow-divider technology more common in flat-die extrusion, as well as a specially configured die head to produce blow molded bottles containing more than 30 layers.
