Tamper evident packaging is a stalwart of safety and awareness in packaging. Not only does it feature strong materials that keep the products inside safe, it alerts consumers to contamination or foul play.

What exactly is tamper evident packaging? Here is the definition from the Food and Drug Administration:

“A tamper-evident package, according to the regulations of the FDA (21 CFR § 211.132), “is one having one or more indicators or barriers to entry which, if breached or missing, can reasonably be expected to provide visible evidence to consumers that tampering has occurred.” In addition, the indicator or barrier must be “distinctive by design,” which means the tamper-evident feature is designed from material not readily available to the public. Therefore, it can’t be easily duplicated. The labeling must also include a description of the safety feature. For blister packaging, each tablet or capsule is individually sealed, so any form of tampering is immediately visible. The product label needs to include a statement similar to the following: “Do not use if blister is cut or broken.”
