Section 268.2 - Definition

Tamper-evident packaging shall mean packaging having an indicator or barrier to entry which, if breached or missing, can reasonably be expected to provide visible evidence to consumers that tampering has occurred. If a breached or missing indicator or barrier would not, in and of itself, provide consumers with such evidence, the packaging may still qualify as tamper-evident if, in conjunction with such device, a printed statement is prominently displayed on the product label so as to alert the consumer of the original presence of the indicator or barrier.
