Round food storage container  

A food-grade reusable lunch box is a lunch box that meets food safety standards and can be used repeatedly without contaminating food or harming human health. This lunch box is usually made of materials such as food-grade plastic or glass and is resistant to high temperatures, freezing and corrosion. They usually have sealing properties, which can effectively maintain the freshness and hygiene of food. Using food-grade reusable lunch boxes can not only reduce the use of disposable lunch boxes and reduce environmental pollution, but also save resources and reduce waste generation.
