Rigid containers are solid, inflexible structures used to hold and protect various products. They are commonly made from materials like plastic, glass, or metal, and are designed to maintain their shape under pressure. These containers are widely used in industries such as food and beverage, pharmaceuticals, and cosmetics to ensure safe storage and transportation. Unlike flexible containers, which can change shape, rigid containers provide a stable environment for their contents. They come in various forms, including bottles, cans, and boxes, and are often sealed to prevent contamination. Their durability makes them ideal for preserving the quality of products over time.
