The state's largest manufacturer of plastic containers plans to open a $5 million manufacturing plant at Campbell Industrial Park in Kalaeloa next month.

Pacific Allied Products Ltd., which manufactures bottles for Coca-Cola, Pepsi and other customers, said the 30,000-square-foot facility and state-of-the-art bottling equipment will expand its output from 60 million bottles a year to about 200 million bottles a year.

"We predict an increase in the demand for plastic bottles because of the growing number of bottled water companies opening in Hawai'i and see this as a continuing trend," says Bernie Coleman, general manager of Pacific Allied.

Pacific Allied manufactures plastic bottles and styrofoam products at a 12,000-square-foot Campbell Industrial Park site adjacent to the new plant.

The company said its styrofoam unit, which makes peanut foam for packaging and other foam products, will remain at its existing plant.
