DuPont, a company famous for the invention of nylon and other plastics, is honoring two non-plastic materials as the top-level winners in its annual competition to honor outstanding new packaging.
The first “Diamond” award was issued to Exal Corp. and Alcoa Rigid Packaging for new “coil to can” (C2C) aluminum bottle manufacturing technology. C2C aluminum bottles use less material and are manufactured at faster speeds to enable a 40 percent weight reduction at a cost comparable to PET and/or glass.
The second diamond winner is Entropy Solutions of Eden Prairie, MN, for a new reusable thermal management system for shipping blood and pharmaceuticals. The package is based on phase change materials such as paraffin or eutectic salt.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
