Custom Seal End with Perforated Top Boxes
Perforating the top panel rather than the end changes what happens when the carton opens. Instead of a small tear at one end, the whole top comes away and the contents are visible and reachable from above. For anything picked from repeatedly, that access matters. We produce a lot of seal end with perforated top box work at ZEE Packaging and the wide opening is the point.
The Whole Top Comes Away
A seal end with perforated top box opens from above.
- Both ends stay glued for tamper evidence
- A perforated top panel tears away entirely
- Contents become visible and reachable at once
- It converts into a dispenser or a display tray
- No knife or scissors are needed
- The remaining structure holds its shape
Most brands choosing a seal end with perforated top box want access from above rather than a small end opening.
Perforation Across A Panel
Tearing a whole panel is harder than tearing a strip.
- The line runs further, so consistency matters more
- Too fine and it opens under transit pressure
- Too coarse and it tears raggedly halfway across
- The tear must follow the board grain where possible
- A clear start point is essential on a wide panel
- We test the full tear rather than a short section
- Full top removal the standard seal end with perforated top box
- Partial tear leaving a hinged flap in place
- Dispenser conversion the opened carton feeding product
- Shelf ready version becoming a display tray
- Window version showing product before opening
- Food grade version for direct food contact
Sizes We Print Regular
Every seal end with perforated top box is built to your product, though these run often:
- 6" x 4" x 4" for a standard retail carton
- 8" x 5" x 5" for a larger product
- 4" x 3" x 3" for a small format
- 10" x 6" x 6" for a bulk carton
- 8" x 6" x 3" for a shallow display format
- 12" x 8" x 5" for a case format
Send us the filled weight and your line spec, since both affect the build.
Board And Print
- SBS C1S at 18pt to 24pt for retail applications
- E flute corrugated for larger case formats
- CCNB and duplex where a grey back is acceptable
- Kraft board for a natural position
- Food grade certified stock where required
- Printed inner walls, visible once the top is removed
Printing the inside is worth doing here. Once the top comes away, the interior walls face the customer for the whole time the carton is in use.

- Water based adhesive on the sealed ends
- No plastic film or tear tape needed

Frequently Asked Questions
Why perforate the top rather than an end?
Because it opens the whole panel. That gives access from above rather than through a small end opening.
Will it tear cleanly across a wide panel?
It will if specified and tested properly. A long tear line needs more care than a short strip does.
Can it become a display tray?
Yes, which is one of its main uses. The opened carton sits on a shelf as a tray.
Will it open in transit?
Not with a correctly specified perforation. Premature opening comes from a cut that is too fine.
Should the inside be printed?
Definitely. Those walls face the customer once the top is removed.
Is it suitable for food?
Yes, in food grade stock. Snack multipacks and dry goods use it constantly.
How much does a seal end box with a perforated top cost?
Rough estimate is $0.25 to $0.70 per unit plain, $0.40 to $1.05 with print and $0.65 to $1.60 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.
