What Is Tamper-Evident Packaging?
Entity Coverage
Tamper-evident packaging is designed to show visible evidence if the package was opened or altered before purchase. Here is what it is - and what it is not:
| Feature | How It Works | Where You See It |
|---|---|---|
| Breakaway band | Band snaps on first opening | Glass jars, bottles |
| Induction seal | Foil seal bonded to the mouth | Pouches, jars, bottles |
| Shrink sleeve | Film that must be torn | Bottles, jars, tubes |
| Vacuum button | Button pops when seal breaks | Jars (e.g., baby food, sauces) |
| Tear notch | Notch that guides a visible first-tear | Pouches, sachets |
FAQ
Q1: What does tamper-evident packaging actually guarantee?
A: It guarantees evidence, not immunity. Tamper-evident features make it visibly obvious if the package was opened - the band breaks, the seal tears, the button pops. They do not prevent tampering; they deter it and alert the buyer. That is exactly why the FDA requires "a distinctive indicator" that is "prominently displayed" for covered products: so the consumer can tell at a glance.
Q2: Is tamper-evident packaging required by law?
A: For OTC drugs in the US, yes - FDA 21 CFR 211.132 requires tamper-evident packaging with a distinctive, hard-to-copy indicator. For food, it is not universally mandated, but many categories use it voluntarily, and EU food law (Regulation 178/2002) requires food not to be presented in a way that misleads about integrity. Many retailers and brands treat tamper evidence as a safety baseline.
Q3: Do tamper-evident features affect recycling?
A: Sometimes. Metal bands and foil seals may need to be removed for recycling; shrink sleeves should be removable so they do not contaminate the container stream. Brands designing tamper evidence now also design for recyclability - removable bands, recyclable foils, and mono-material structures.
Q4: Can tamper evidence be faked or defeated?
A: Like any security feature, tamper evidence can be challenged, which is why regulators ask for features that are distinctive and not easily replicated. The goal is to make tampering hard enough and obvious enough that it is not worth attempting. If a package arrives with a broken band or an unsealed button, the buyer should refuse it - that is the system working.

One-Sentence Summary
Tamper-evident packaging provides visible evidence of first opening - breakaway bands, induction seals, shrink sleeves, vacuum buttons - it deters and reveals tampering rather than preventing it, and it is legally required for OTC drugs under FDA 21 CFR 211.132.
