Tamper-evident seals are security features designed to show if a product or package has been opened or altered. These seals can be made from various materials, such as plastic or paper, and often include unique designs or markings. When the seal is broken, it leaves a visible mark or damage, indicating that tampering has occurred. These seals are commonly used in industries like food and beverage, pharmaceuticals, and electronics to ensure product integrity. By using tamper-evident seals, manufacturers can help protect consumers from potential harm and maintain trust in their products.
