Custom Full Overlap Container FOL
Most shipping cartons meet in the middle at the top and bottom, leaving a seam right where impact tends to land. A full overlap changes that. The outer flaps run the entire width of the box and lay over each other completely, doubling the board across both faces. We produce a lot of full overlap container fol work at ZEE Packaging and this is the format we recommend when a regular carton keeps failing.
Double Board Where It Matters
A full overlap container fol puts two layers across the top and bottom.
- The outer flaps extend the full width rather than meeting in the middle
- That gives you double thickness across both faces
- Impact resistance improves considerably over a regular slotted carton
- There is no open seam for a corner to punch through
- Stacking strength improves because the load spreads evenly
- It costs a little more board, though far less than double wall
Most operators move to a full overlap container fol after seeing corner failures on a standard carton.
When It Is The Right Choice
It is not always the answer, so worth knowing where it fits.
- Heavy products that punish a standard flap arrangement
- Long transit routes with multiple handling points
- Anything shipped internationally through several networks
- Products with hard corners that press into the flaps
- Repeated reuse, where the extra layer extends the life
- Where double wall would be overkill and add too much cost
- Standard full overlap container fol the everyday specification
- Half slotted version open top for tray applications
- With a die cut insert protecting fragile contents
- Double wall full overlap for genuinely heavy freight
- Printed exterior branded shipping formats
- Water resistant coated for humid or cold storage
Sizes We Print Regular
Every full overlap container fol is built to your product, though these run often:
- 8" x 6" x 4" for a standard order
- 12" x 9" x 6" for a mid size shipment
- 16" x 12" x 10" for larger goods
- 18" x 14" x 12" for bulk items
- 20" x 16" x 14" for heavy freight
- 24" x 18" x 12" for oversized products
Send us the filled weight and the journey, since both drive the specification more than dimensions alone.
Board And Construction
- B flute as a baseline for most applications
- C flute where cushioning matters more than print quality
- Double wall for genuinely heavy or palletized freight
- Kraft corrugated for plain shipping formats
- Water resistant coating for damp warehouse conditions
- Flexo printing for one or two colors on the exterior
The trade off is board usage. A full overlap container fol uses more material than a regular slotted carton, though considerably less than stepping up to double wall.
Materials Worth Considering
- Recycled corrugated, standard across these grades
- FSC certified board, certificate available on request
- Soy based ink where the exterior is printed
- Paper tape rather than plastic on the seal
- Reusable for return shipments, since the structure survives
- Right sizing so you are not shipping air

- 100 unit minimum, so smaller operations can order properly
- Free 3D mockup and flat proof before anything prints
- Free dieline drawn by our own designer
- Physical sample on request to test under real load
- Urgent turnaround at 5 to 8 business days
- Free shipping worldwide with nothing hidden
Frequently Asked Questions
How much stronger is it really?
Meaningfully on impact and corner resistance, since the faces carry double board. It is a genuine step up rather than a marginal one.
Is it better than double wall?
Different rather than better. Double wall gives more crush strength, a full overlap gives better face protection at a lower cost.
How much is a full overlap FOL container?
Rough estimate is $0.70 to $1.80 per unit in B flute, $1.20 to $2.80 in C flute and $2.20 to $5.00 in double wall at moderate quantity. Size moves it. Shipping is included in our price. This is estimate only, so ask our team for a exact quote.
Does it use much more board?
More than a regular slotted carton, considerably less than double wall. That balance is why the format exists.
Can it be printed?
Yes, usually flexo in one or two colors. Litho lamination is possible where retail quality print matters.
Is it reusable?
Better than most shipping formats, since the doubled flaps survive repeated opening far better than single ones.
Which flute should we choose?
B for general shipping, C where cushioning matters. We would ask about your product weight before advising properly.
