Tamper evidence
Updated
On this page5
A drink is consumed directly from the container, which makes this category more sensitive than most.
Expected rather than required
There is no general tamper-evident packaging requirement for ordinary beverages.
What there is: a strong consumer and retailer expectation, and a practical need in a product that is opened and drunk immediately.
What each closure gives you
Crown caps are inherently tamper-evident: they cannot be removed and replaced.
ROPP forms a pilfer band at capping that separates on first opening.
Cans are tamper-evident by construction.
Plain screw caps are not, which is why a screw-capped beverage usually carries a band or a tamper-evident closure design.
Swing-tops are not, and are the format where a separate seal matters most.
Why it matters here
The product goes straight to the mouth with no preparation step in between.
And in a live or carbonated product a broken seal is also a safety signal: a bottle that has been opened has lost pressure and may have been recontaminated, and the customer cannot tell without evidence.
Which makes a visible seal a quality communication as much as a security one.
Shrink and bands
A shrink band over the closure is cheap and quick with a heat gun.
A full sleeve can carry the whole label, which solves the wet-label adhesion problem at the same time and is common in this category for exactly that reason.
Whichever, apply after the bottle is dry, and check the band survives a fridge and an ice bucket alongside the label.
