Seal & Protect the Easy Way!

Products that require a special seal, or tamper-evident packaging, are meant to keep items out of the hands of those who shouldn't have access to it. This added security protects and keeps items fresh for the intended customer. 

Why Was Tamper Evident Packaging Created? 

In Chicago of 1982, the rise of better security for products was increased. Unbeknownst to customers, Tylenol was intentionally laced with deadly cyanide capsules. These bottles were placed in multiple locations throughout the city. 

People were being poisoned and hospitalized, leaving authority officials to nail down the common denominator. Every bottle of Tylonol was recalled, costing Johnson & Johnson $100 million dollars. Companies were then required to have better safety measures, which created the start of tamper-evident packaging.

Tamper-Proof vs Tamper-Evident Packaging

Tamper evident packaging provides an airtight seal that ensures customers no one has touched the product. Packaging that falls under tamper-evident consist of food containers, caps and closures, and shrink bands. This packaging is commonly used within the food and beverage, pharmaceutical, and personal care. 

Tamper-proof would mean it cannot be tampered or messed with at all. Tamper-evident is the correct term to use because we know it will eventually get opened by someone.
