Tupperware Brands, the iconic maker of plastic food containers, has officially filed for bankruptcy after facing several years of declining sales and a challenging economic environment. The company's attempts to revive its fortunes have faltered, leading to a significant drop in demand for its once-beloved colorful containers. Despite being a staple in American households, Tupperware's relevance has waned, resulting in plummeting stock prices and the closure of its last US factory. As the company moves forward with Chapter 11 proceedings, it may explore options such as a potential sale.
