Can shrink sleeves include tamper-evident features?

Yes, shrink sleeves can include tamper-evident features, most commonly a perforated band applied across the cap-to-bottle join. Breaking the perforation to open the product leaves a visible, irreversible sign that the container has been opened.

A tamper-evident sleeve is typically a narrower band, rather than a full-body sleeve, positioned specifically over the closure so it must be torn to remove the cap. The perforation is engineered to tear cleanly with normal consumer force while resisting accidental tearing during shipping and handling. This same tamper-evident principle can also be combined with a full-body 360-degree sleeve, where the design continues down over the cap seal in addition to covering the rest of the container, giving both branding coverage and tamper evidence in one component.

For pharmaceutical, food, and beverage products, this kind of visible tamper evidence is often expected by regulators or retailers as part of demonstrating product integrity from the factory to the point of sale. Because the tear performance depends on film type, perforation pattern, and application tension, tamper-evident sleeves should be sampled and tested on the actual container and capping equipment before full production to confirm the band tears reliably without failing prematurely or being too difficult to open.
