Twinkies were invented at Hostess' Schiller Park, Ill., plant in 1930.

SCHILLER PARK, ILL. — The facility where Twinkies were invented in 1930 will be closed later this year after Hostess Brands, L.L.C. announced it will shutter its Schiller Park bakery “to enhance its production and distribution capabilities and efficiencies.”

“Hostess has brought these great brands back to the marketplace,” said Bill Toler, chief executive officer of Hostess. “We have invested heavily in all facilities to improve worker conditions and efficiencies in a very highly competitive environment and marketplace. While the old Hostess company was in bankruptcy, many competitors took over the shelves and are tenaciously defending their business, and thus we must be highly efficient and technologically advanced to compete. As a result, we have invested in more efficient production capabilities and need to streamline our manufacturing infrastructure and protect our ability to compete.”

Hostess closed all its bakeries in November 2012, as it filed for bankruptcy, but several plants were acquired in 2013 as part of the $410 million purchase by HB Holdings L.L.C., an affiliate of Apollo Global Management L.L.C. and Metropoulos & Co., of most of the snack cake assets of Hostess Brands Inc. The company has three other baking plants in Indianapolis; Columbus, Ga.; and Emporia, Kas. Hostess has made production capacity expansions at the Emporia plant since the 2013 acquisition.
