Custom Side Lock Six Corner
The six corner build already gives you three panels folding at each end. Adding a side lock puts a tab and slot into that fold so the panels hold each other mechanically rather than relying on the fold alone. It is a small addition that changes how the tray behaves under load. We produce a lot of side lock six corner work at ZEE Packaging and the extra security is what clients ask for.
Six Corners Plus A Lock
A side lock six corner adds engagement to the fold.
- Each end forms from three panels as usual
- A tab and slot lock those panels together
- The fold cannot work loose under weight
- No glue or tape is needed anywhere
- It ships flat with nothing pre assembled
- Recycles as one clean piece with no adhesive
Most operators choosing a side lock six corner have had a plain six corner open up under a heavy load.
Where The Lock Makes The Difference
A plain fold is fine until it is not.
- A plain six corner relies on friction alone
- Under weight those panels can gradually separate
- The lock stops that from happening entirely
- Repeated handling puts stress on the fold
- Long transit routes work a plain fold loose
- For light static display it is often unnecessary
- Open side lock six corner tray the standard build we run
- With a separate lid shipping sealed then displaying
- With a tuck top the lid attached to the tray
- Front cut down version product visible from the front
- Divided tray compartments for several SKUs
- Food grade version for bakery and catering use
Sizes We Print Regular
Every side lock six corner tray is built to your product, though these run often:
- 10" x 7" x 3" for a small counter tray
- 12" x 9" x 4" for a standard format
- 14" x 10" x 4" for a larger unit
- 8" x 6" x 3" for compact items
- 16" x 12" x 5" for a bulk tray
- 8" x 8" x 4" for a square format
Send us the loaded weight, since the lock depth is specified against it.
Board And Print
- E flute corrugated for lighter trays
- B flute where the tray carries real weight
- SBS C1S for a lightweight retail version
- Litho laminated corrugated for full color print
- Kraft corrugated or board for a plain build
- Food grade certified stock where food is involved
The slot cut has to be precise. Too shallow and the lock does nothing, too deep and it weakens the fold, so we sample it rather than assuming.
Materials Worth Choosing
- Recycled board and corrugated, standard in these grades
- FSC certified stock, certificate available on request
- Soy based ink through the whole run
- No adhesive at all in the construction
- No lamination, so it recycles cleanly
- Right sizing so no board is wasted per tray

Frequently Asked Questions
How is it different to a plain six corner?
A tab and slot lock the end panels together. A plain version relies on friction, which can work loose.
Does the lock cost much to add?
Very little. It is a die cut feature rather than an extra component or production stage.
Will it hold heavy products?
Considerably better than a plain fold. Send us the weight and we specify the lock depth accordingly.
How fast does it assemble?
A few seconds once staff learn it. Slightly slower than a plain six corner, still faster than taping.
Does it need glue?
No. Everything holds mechanically, which is the point of the design.
How much does a side lock six corner tray cost?
Rough estimate is $0.40 to $1.05 per unit in plain board, $0.65 to $1.60 with print and $1.20 to $2.80 for litho laminated at moderate quantity. Size moves it. Shipping is included in our price. This is estimate only, so ask our team for a exact quote.
Can it hold food?
Yes, in food grade stock. It works well for bakery and catering trays.
