A potential alternative competitor to the dominance of expanded polystyrene eps foam in longdistance protective packaging could open new doors with the help of dupont and an emerging company. Coldpack, offers a coextruded polyolefin film using reflective, metalized films of four to seven layers that keeps temperatures stable and constant for packages shipped by air or truck. Its squareshaped airliner film folds flat to save room when not in use, can be inflated by either air or inert gas, and fits neatly into a corrugated box while looking like a flexible version of a foam cooler. Eps foam packaging accounts for about 90 percent of airline packaging. Coldpack is a particularly relevant technology where temperature stability is important during transport, such as with vaccines and seafoods.the wilmington, debased specialty materials company will provide coldpack with several olefin materials, including surlyn and bynel, that could offer even stronger heattransfer properties. In 2009, coldpack plans to launch its packaging in rollstock that allows converters to produce the film in whatever shape or size arrangement a customer desires and in larger volumes.
