Custom Seal End With Tear Open Box
Glued ends give you tamper evidence and then leave the customer struggling to get in. A tear strip solves that. A perforated line runs across the end panel, the customer pulls it, and the carton opens cleanly without a knife or a fight. We produce a lot of seal end with tear open box work at ZEE Packaging and the opening experience is what it fixes.
Sealed Shut, Easy To Open
A seal end with tear open box balances security and access.
- Both ends are glued during production
- A perforated strip provides a defined opening point
- No knife or scissors are needed by the customer
- The tear leaves a clean edge rather than a ragged one
- Tamper evidence stays intact until it is pulled
- It opens in a second rather than requiring effort
Most brands choosing a seal end with tear open box have had complaints about sealed cartons being hard to open.
Perforation Quality Decides Everything
A bad tear is worse than no tear strip at all.
- Too fine and it opens accidentally in transit
- Too coarse and customers give up and use a knife
- The tear line must run with the board grain
- A clear start point helps people find it
- Board caliper changes how the perforation behaves
- We test the tear physically before running
- End tear strip the standard seal end with tear open box
- Side tear version opening along a side panel
- Full overlap format doubled board at the ends
- With a reclosable tab closing again after opening
- Window version showing product through a die cut
- Food grade version for direct food contact
Sizes We Print Regular
Every seal end with tear open box is built to your product, though these run often:
- 3" x 2" x 6" for a standard retail item
- 4" x 3" x 8" for a larger product
- 2" x 2" x 5" for a small format
- 6" x 4" x 9" for a bulkier item
- 5" x 3" x 7" for a mid size product
- 8" x 6" x 10" for a large carton
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
- CCNB and duplex where a grey back is acceptable
- Kraft board for a natural position
- Matte, gloss and soft touch lamination
- Food grade certified stock where required
- Printed tear instruction beside the start point
Printing a small instruction near the tab is worth doing. Plenty of customers miss a tear strip entirely and reach for scissors regardless.

Frequently Asked Questions
Why add a tear strip?
Because sealed ends are hard to open otherwise. Customers end up using a knife, which risks damaging the product.
Will it open in transit?
Not with a correctly specified perforation. Premature tearing happens when the cut is too fine for the board.
What is the price of a seal-end tear-open carton?
Rough estimate is $0.20 to $0.60 per unit plain, $0.32 to $0.85 with print and $0.50 to $1.30 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.
Will the tear look clean?
It will if tested at proof stage. A ragged edge is the fastest way to make a pack look cheap.
Can it reclose afterward?
Only with a locking tab added. A plain tear strip leaves the carton open once used.
Do we need a printed instruction?
We would recommend it. Without one plenty of customers miss the strip entirely.
Is it suitable for food?
Yes, in food grade stock. It is standard across snacks, cereals and dry goods.
