Ear Lock Boxes: A Closure That Doesn't Rely on Tape
Tabs fold and lock into slots, no adhesive to weaken with age, heat, or a rough shipping route.
What Makes an Ear Lock Box More Secure Than Tape
Ear lock boxes close with folding tabs, often called "ears" for their shape, that tuck into slots cut into the box body. Once folded in, the tabs hold the flap shut mechanically. There's no adhesive involved, which means nothing to weaken with heat, age, or humidity over a long shipping route.
A taped box can fail slowly, adhesive loses grip over time or in hot conditions. An ear lock box either holds or it doesn't, and once the tabs are folded in, opening it takes a deliberate, visible action, not an accidental jolt in transit.
Shahwaze Packaging manufactures ear lock boxes for e-commerce, subscription, and retail brands across the USA. See our Mailer Boxes style page for how ear lock compares to our other closure types.
Ear Lock or Standard Tuck-Top: When the Extra Security Is Worth It
Standard tuck-top closures work fine for most shipments. Ear lock earns its place in a few specific situations.
For the full comparison across all four closure types we offer, see our Mailer Boxes page's closures table.
Ear Lock and Cherry Lock Are Not the Same Closure
Some suppliers use "ear lock" and "cherry lock" interchangeably. They're different mechanisms. Cherry lock is a rounded tab that clicks into a circular die-cut hole, mostly a styling detail rather than a security feature. Ear lock is the structural, security-focused closure covered on this page. See our Tuck-End Boxes page for the fuller breakdown of tab lock, tongue lock, and cherry lock.

Frequently Asked Questions
A box that closes with folding tabs, called "ears," that tuck into slots cut into the box body, creating a mechanical closure with no tape needed.
In a meaningful way, yes. Tape can lose grip over time, in heat, or in humidity. A mechanical tab-and-slot lock either holds or it doesn't, and it doesn't degrade the same way adhesive does.
For heavier products, items that shift weight during transit, or longer and rougher shipping routes, situations where a standard tuck flap has a real chance of popping open under pressure.
No. Cherry lock is a rounded tab in a circular hole, mostly decorative. Ear lock is a structural, security-focused closure. See our Tuck-End Boxes page for the full comparison.
