TAMPER-EVIDENT PACKAGING

Opening Experience
A sealed top plus zipper gives customers visible first-opening evidence and then a familiar way to close the pouch after use.
The top section remains intact and the zipper is inaccessible.
The customer removes or tears the tamper-evident section.
The zipper becomes the normal reclosure while the changed top shows that first access has occurred.
Pouch format options
Tamper-evident features can be adapted to different pouch formats when the top area provides enough room for the seal and opening path.

For retail products that also need zipper reclosure.

For samples, supplements, food portions and compact retail packs.

For larger food, coffee or pet-product packages.

Can combine tamper evidence with a CR reclosure when both functions are required.

Tamper-evident claims
Tamper-evident packaging is designed to reveal opening or disturbance; it should not be described as impossible to open or impossible to tamper with.
Accurately describes visible evidence of first opening or interference.
No flexible pouch should be marketed as impossible to defeat without specific evidence supporting that claim.
Some regulated products have specific tamper-resistant packaging requirements that should be reviewed separately.
It is packaging designed to provide visible evidence if the package has been opened or disturbed before use.
Yes. A sealed top can provide first-opening evidence while a zipper below it provides reclosure after opening.
No. Tamper evidence shows prior opening, while child resistance controls access by young children.
FDA consumer guidance notes that tamper-evident packaging provides visible evidence of disturbance and that OTC packaging cannot be considered 100 percent tamper-proof.
