What is a key requirement for tamper-evident packaging?

Tamper-evident packaging is designed to protect the integrity of a product by providing visible evidence that the packaging has been disturbed or manipulated. The key requirement is that it must prevent alteration after packaging, which ensures that consumers can trust that the medication or product they are using is safe and has not been tampered with. This is crucial in the pharmaceutical industry, where the risk of tampering can lead to serious health consequences for patients.

The other options do not align with the fundamental purpose of tamper-evident packaging. For instance, while it is true that pills must be secured effectively, stating that it is not necessary for pills overlooks the need for safety across all pharmaceutical products. Displaying prescription details is important for identifying medications but is not a requirement of tamper-evident packaging itself. Lastly, the concept of reuse is contrary to the intent of tamper-evident packaging, as reusing packaging can compromise safety and would potentially defeat the purpose of indicating whether a product has been altered. The main focus remains on ensuring that packaging protects against tampering to guarantee safety for consumers.
