Bates Valve Bag Company

In 1901, Bates established a valve bagging manufacturing plant in Nyack, New York. Bates was known to be specialize in packaging systems for cement, salt, and plaster.

Renowned for innovation, they transitioned from cotton to paper bags in 1925, a move driven by World War I's burlap shortage, offering cost efficiency, sanitation, and convenience.
