27 Fall 2016 Pharmaceutical & Medical Packaging News • forming 5-in.-deep trays that weren't too intricate. They ran the material "on existing tooling for a styrene part, and there wasn't a lot difference in shrinkage," reports Tom Tomasic, executive director. "It cuts very clean." With shrink characteristics identi- cal to HIPS, "there would be no added expense of a new tool" should companies decide to switch, says Petrie. "CDI sees advantages and is evaluating Eastalite in sealed sterile barrier packaging as well." Adds Ortwein: "It seems to run fast- er and easier [than HIPS], and there is good uniformity, because it processes similar to PETG. It's form friendly and easy to manage through heat. We didn't even change the profile settings [from that used for a HIPS thermo- form]—we didn't know where to start, so we just put the roll on." Eastalite can speed up cycle time. Petrie from Eastman explains that's because Eastalite has a reduced density compared with HIPS. Jim Banko, vice president of sales for Pacur, says that because Pacur PETG Foam made from Eastalite "seems to take heat fast, and it dis- sipates fast," speeding up cycle time by as much as 50% is possible. In addition, thermoforming tempera- tures are lower than those for HIPS, creating energy savings as well, he says. Computer Designs has been intro- ducing the material to its medi- cal device manufacturer customers and suggesting where to begin. For instance, "the safest place to make a change would be a work-in-progress handling tray," says Tomasic. With such WIP trays, Clark of East- man says that the burden of proof would be lower, and the validations not as intense. Ortwein says that he is currently working with a few customers, includ- ing one with a nonsterile application that would eliminate the need for CSR wrap. Testing is also well underway. Petrie reports that Eastman has tested com- plete structures made from Eastalite both before and after sterilization and that it has completed biocompatibility testing. S p e a k i n g o f t h e c o l l a b o r a t i o n between Computer Designs, Pacur, and Eastman, "We've all been able to work together to help each other," says Petrie. "The support chain has been tre- mendous," adds Tomasic. 0
