Manufactured by the B.F. Goodrich company from the 1930s -1950s, the family of Seal Sac products included everything from individual food bags and appliance covers to aprons and curtains. The products were made of a unique plastic blend, known as Koroseal, which allowed the synthetic fabric to be pliable, stain-resistant, and washable. The Koroseal product was sold off in a buy out of the B.F. Goodrich company as they focused on the rubber tire market. Becoming its own company in 1988, Koroseal shifted its efforts away from kitchen accessories and focused on the need for commercial vinyl wall coverings.
