“It seems hard to believe it now, but people did not know how to open the Plastic Zipper Food Bags,” Steven Ausnit, developer of the original Zipper, recently told an audience at Marquette University. He recalled that sometime around the early 1960s, his company persuaded Columbia Records to try a plastic sleeve with the zipper on top for albums. “At the final meeting, we were all set to go. The guy called in his assistant, handed her the sealed bag and said, ‘Open it.’ I thought to myself, Lady, please do the right thing! The more she looked at it, the more my heart sank. And then she tore the zipper right off the bag.”
Ausnit, who fled Communist Romania with his family in 1947, had been experimenting with plastic zippers since 1951. That was when he, his father (Max) and his uncle (Edgar) purchased the rights to the original plastic zipper, designed by a Danish inventor named Borge Madsen, who had no particular application in mind. They formed a company called Flexigrip to manufacture the zipper, which used a plastic slider to seal two interlocking grooves together. When the slider proved costly to manufacture, Ausnit, a mechanical engineer, created what we now know as the press-and-seal type zipper.
In 1962, Ausnit learned of a Japanese company called Seisan Nihon Sha, which had figured out a way to incorporate the zipper into the bag itself, which would cut production costs by half. (Flexigrip was attaching its zippers to bags with a heat press.) After licensing the rights, the Ausnits formed a second company called Minigrip; their big break came when Dow Chemical asked for an exclusive grocery-store license, ultimately introducing the zipper food bags to a test market in 1968. It wasn’t an immediate success, but by 1973, it was both indispensable and adored. “No end of uses for those great Ziploc bags,” Vogue told readers that November. “From holding games to keep the young occupied on the long drive to the mountains, to safe storage places zipper cosmetics bags, first-aid supplies zipper bags and stand up plastic zipper food bags. Even your wig will be happier in a Ziploc.”
