A company that produces 20 million colorful cartons per month for makers of drugs, cosmetics and clothing is buying a third building in Commack as part of a $6 million expansion.

Beyer Graphics Inc. is purchasing 40 Austin Blvd., a 33,000-square-foot facility that it has rented for 10 years. The building is adjacent to the company’s operations at 30 and 50 Austin Blvd.

The expansion is being supported by Suffolk County with $272,500 in tax breaks, including $220,688 off property tax bills over 10 years, or a 27.5 percent reduction.

Company president Daniel Beyer said he plans to install $2 million in new equipment that will help to add five people to a payroll of 98.

Records show employees earn, on average, $79,250 per year, excluding medical insurance and retirement benefits.

The company supplies folding cartons to local pharmaceutical and dietary supplements companies, including vitamin behemoth NBTY in Ronkonkoma, and generic drugmakers Contract Pharmacal Corp. and LNK International Inc., both in Hauppauge, and Hi-Tech Pharmacal in Amityville, Beyer said.

Beyer Graphics prints, folds and glues the boxes used to sell individual bottles of vitamins and over-the-counter drugs in stores.

Beyer said his father, William Beyer Sr., started the business in 1982 in West Babylon to manufacture packaging for apparel makers. Beyer Graphics still produces the cartons used to sell Fruit of the Loom underwear, Jerzees athletic shirts and other clothing — but that only accounts for about 20 percent of sales today.

“In the 1990s, as the apparel industry increasingly moved offshore to Asia, we had to reinvent the company,” Beyer told the board of the county’s industrial development agency last month. “We decided to focus on meeting the packaging needs of the pharmaceutical and cosmetics industries.”

In addition to its Suffolk County operation, Beyer Graphics has a subsidiary in Hong Kong and a business partnership in Honduras.

Anthony J. Catapano, executive director of the Suffolk IDA, said, “Beyer Graphics is an example of a local company benefiting from the county’s growing pharmaceutical industry.”
