Evidence bags are specialized containers used in forensic science to securely store and protect physical evidence collected from crime scenes. These bags are typically made of durable materials, such as plastic or paper, and are designed to prevent contamination or loss of evidence. Each bag is usually labeled with important information, including the case number, date, and description of the contents. When law enforcement officers collect evidence, they place items in evidence bags to maintain a clear chain of custody. This process ensures that the evidence remains intact and can be reliably used in legal proceedings. Proper handling and storage in evidence bags are crucial for the integrity of investigations involving crime scenes, forensic science, and legal cases.
