WEB EXCLUSIVE: DuPont Packaging, Wilmington, Del., has introduce the second in a series of online predictive modeling tools that promises to simplify tie-layer material selection, a critical step in multilayer packaging design. The company offers the "DuPont Tie Resin Selector" on its website (see below) as the first step in selecting the best resin. Users start by identifying two materials to be joined together and the Selector provides a short list of recommended grades of DuPont tie resins grouped by type of extrusion process. The Selector includes links to data sheets for recommended grades, to other relevant literature, and to a customer-service contact for sample ordering and inquiries. Its database includes more than 40 grades of DuPont ‘s Bynel coextrudable adhesives and several grades of Elvax EVA copolymer and Nucrel acid copolymers.

“Selecting the right coextrudable adhesive ensures that dissimilar polymers bond—and stay bonded—from manufacturing through consumer use. Selecting the right adhesive is critical, but it doesn’t have to be frustrating,” says DuPont technology fellow Barry Morris. The Selector is the latest addition to a suite of tools that DuPont uses with its customers to help optimize packaging structures and processes and is one of two now available on the web. The other is the DuPont Save tool for calculating total packaging cost using alternative sealants. Says global eMarketing leader Mike Hiteshew, “DuPont computer modeling and simulation tools save development costs and time by helping our customers identify cost-effective material combinations and processes. Stay tuned for more web-based tools in the future.”

  • Density & Molecular Weight in Polyethylene

    This so-called 'commodity' material is actually quite complex, making selecting of the right type a challenge.

  • Melt Flow Rate Testing–Part 1

    Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.

  • Plastics That Conduct Heat

    Helping electronics, lighting, and car engines keep cool are some new roles for hermoplastics that are formulated to replace metal or ceramic.
