The BrightPak container protects and dispenses sensitive foods and beverages using direct or indirect pressure or pump systems. Designed by ATMI, Inc., Danbury, Conn., with assistance from Plastic Technologies, Inc., Holland, Ohio, the liner-in-bottle system replaces large glass bottles for photolithography chemicals used to manufacture semiconductors, LEDs and flat-panel displays.
ATMI's double-containment design eliminates bubble formation and particle defects caused by pump and vacuum delivery containers. It also protects the contents from external contamination, accidents (spills) and operator errors. The container is made from two preforms, one for the 4.6-liter, paneled, amber polyethylene terephthalate (PET) bottle and one for the collapsible rigid polyethylene naphthalate (PEN) liner, which holds the product.
