Cheektowaga packing company Cello-Pack Corp. has been acquired by a downstate packaging firm, Trinity Packaging Corp.

Trinity is expected to continue Cello-Pack’s local operations, at 55 Innsbruck Drive, where about 150 people work.

Employment at the Cheektowaga facility is not expected to change, according to documents filed with the Erie County Industrial Development Agency, which granted tax breaks for the construction of the Innsbruck Drive facility in 2002.

“They fully intend to keep their operations in Cheektowaga,” said Karen Fiala, the IDA’s assistant treasurer.

Trinity, in a letter to customers and suppliers, said the deal will expand its printing capabilities, especially in 10-color flexographic printing, specialty films and lamination.

Cello-Pack six years ago spent $4 million on a 10-color flexographic printing press that runs faster, can produce larger packaging and can be switched from one order to the next more rapidly.

“The purchase of Cello-Pack Corp. allows Trinity to increase its value-added offerings to our existing customer base, while expanding on our current capabilities,” Trinity said in the letter.

“The synergies between the two companies cannot be understated,” Trinity said. “Cello-Pack is one of the fastest-growing companies in the industry and has full-service capabilities, including design, engineering, prepress, printing, laminating and pouch converting.”

The two companies together have almost 160 years of experience in the bag-manufacturing business, with Trinity founded in 1917 and Cello-Pack in 1948.

The terms of the deal were not disclosed.

Trinity, which is headquartered in Armonk, also has U.S. facilities in Lewiston, Pa.; Pueblo, Colo.; and Rocky Mount, Va., along with a factory in Shanghai, China.
