Tamper-evident shrink sleeve

Prooftag offers tamper-evident shrink sleeves to ensure product integrity and track & trace

A tamper-evident shrink sleeve is generally used to assure consumers that a product is intact. It acts as a seal to prove that a product has never been opened.

A tamper-evident product does not prevent the product from being physically opened, but must be able to prove that it has been opened. It is a tampering indicator that acts as a deterrent to those who wish to tamper with an opening.

Shrink Sleeves

Beyond this mechanical function, Prooftag offers track & trace
and marketing elements.

We offer several types of materials to meet your needs in terms of shrink level, type of container or technical and environmental constraints.

They are resistant to moisture, abrasion and friction.

To facilitate opening, the product can be perforated.

The products are available in rolls or pre-cuts.

Prooftag offers you tamper-proof shrink sleeves with a choice of several digital marketing, track & trace
and security technologies
