Custom Seal End Bottom Box
Sealing only the bottom rather than both ends gives you something useful. The base is glued shut permanently, so it never opens under weight, while the top stays as a tuck for filling and access. You get base security without committing to a fully sealed carton. We produce a lot of seal end bottom box work at ZEE Packaging and the split approach suits plenty of products.
Sealed Below, Open Above
A seal end bottom box glues one end only.
- The base is glued shut during production
- The top remains a tuck flap for filling
- The base cannot open under downward weight
- Filling happens from the top rather than either end
- It ships flat despite the pre glued base
- Customers open from the top rather than tearing
Most brands choosing a seal end bottom box want a secure base without the cost of sealing both ends.
Where The Sealed Base Matters
Weight is what makes this worth doing.
- Powders and granules that must not escape below
- Liquids and anything with real density
- Cartons lifted repeatedly by hand
- Products where a base failure ruins the contents
- Long transit routes with multiple handling points
- Unnecessary for light retail items on a shelf
- Standard seal end bottom box the everyday build we run
- With a tuck and tongue lock top a more secure closure
- With a full overlap base doubled board below
- Window version showing product through a die cut
- With a die cut insert holding contents steady
- Food grade version for direct food contact
Sizes We Print Regular
Every seal end bottom box is built to your product, though these run often:
- 3" x 2" x 6" for a standard retail item
- 2" x 2" x 5" for a small format
- 4" x 3" x 8" for a larger product
- 3" x 3" x 5" for a candle or jar
- 5" x 3" x 7" for a mid size item
- 6" x 4" x 9" for a bulkier product
Send us the filled weight, since the glue pattern on the base follows from it.
Board And Print
- SBS C1S at 18pt to 24pt for retail applications
- CCNB and duplex where a grey back is acceptable
- Kraft board for a natural or artisan position
- Corrugated for heavier shipping formats
- Matte, gloss and soft touch lamination
- Food grade certified stock where required
Glue coverage on the base is what we sample. A weak bond fails under load, so we test it with your actual product weight rather than assuming.

Frequently Asked Questions
Why seal only the bottom?
Because the base carries the weight. Sealing both ends costs more and makes filling and opening harder.
How much weight will the base hold?
Considerably more than a tuck. Send us the filled weight and we specify the glue pattern accordingly.
How much does a seal end bottom box cost?
Rough estimate is $0.18 to $0.55 per unit plain, $0.30 to $0.80 with print and $0.48 to $1.25 with finishing at moderate quantity. Volume moves it. Shipping is included in our price. This is estimate only, so ask our team for a exact quote.
Does it ship flat?
Yes, despite the pre glued base. It opens into shape when the top flap is lifted.
Is the top secure enough?
For most retail products, yes. A tongue lock helps where the pack gets handled repeatedly.
Is it tamper evident?
The base is, though the top is not. For full tamper evidence we would seal both ends.
Is it suitable for food?
Yes, in food grade stock. It is common for powders, cereals and dry goods.
