Why a hinge matters
Nothing gets put down and lost. With a lift-off lid there is always a moment where the lid is somewhere else, and that moment is where lids end up on car seats and kitchen counters.
It also means the pack opens to a fixed angle and stays there, so the product is presented rather than tipped out.
The four locks
Metal locker flip: a slide catch formed into the metal. Move it, lift the lid.
Button locker flip: a button held down while the lid lifts.
Three-button flip: three catches that have to be released together, which is the most resistant of the four.
Click and lock: the same latch used on the slider, adapted to a hinge, and the flattest.
What flips suit
Anything opened in front of other people. It is the format that does the most work at the moment of opening, so it suits chocolate, mints, pre-roll multipacks and anything positioned as a gift or a treat.
It is also the easiest format to fit a compartmented insert into, because the lid swings clear and the whole tray is exposed at once.
Slider or flip
Slider if the pack needs to be as thin as possible or lives in a pocket. Flip if the opening moment matters, or if you want the lid to stay attached.
Both are tested to the same protocol, so this is a decision about how the pack gets used rather than about compliance.
