Tamper evident packaging is designed to show visible signs if a product has been tampered with. This type of packaging often includes seals, shrink bands, or breakable caps that must be removed to access the product. If the seal is broken or damaged, it indicates that the product may have been compromised, helping to ensure consumer safety. This packaging is commonly used for food, pharmaceuticals, and cosmetics to protect against contamination and unauthorized access. By providing clear evidence of tampering, it helps consumers make informed decisions and enhances trust in brands like Nestlé and Pfizer.
