Custom seal end boxes for US food, pharma, retail, and cosmetic brands needing a tamper-resistant sealed closure. We print low-MOQ from 100 units — the seal-end construction glue-seals both ends of the carton, ideal for tablets, dry food, retail SKUs that need to arrive sealed, and any product requiring tamper-evident closure.
For US food, OTC pharma, supplement, retail, and cosmetic brands needing tamper-evident sealed closure at both ends of the carton.
About Custom Seal End Boxes
Seal-end boxes: tamper-evident, sealed both ends
Seal-end (straight-tuck-seal) cartons are the standard for products that must arrive sealed: OTC tablets, dry food, retail SKUs at big-box, cosmetic starter kits. The manufacturer glue-seals both ends at production; the customer opens the carton by tearing along a perforated line or peeling the seal. Any prior opening leaves visible damage — the tamper-evidence signal every regulated category needs.
When to use seal-end vs tuck-end vs auto-bottom
Seal-end wins when: tamper-evidence matters (OTC, pharma, food); the carton must arrive sealed (retail); or the product is small/loose enough that an unlocked tuck flap would let it fall out. Tuck-end wins when: you need cheapest per unit and the customer opens/closes multiple times. Auto-bottom wins when: assembly speed matters and the box needs load-bearing strength. Standard seal-end build is 18-24pt SBS with either a tear-strip perforation or a peel-away glue-seal for opening.

Materials, print, and finish options
Seal-end (aka straight-tuck-seal or tuck-flap-glue) closure glue-seals both the top and bottom tuck flaps at manufacture — the customer opens the box by tearing along a perforated line or peeling the glue-seal. Delivers tamper-evidence (any opening leaves visible damage), better product protection (nothing falls out mid-transit), and a cleaner unboxing than an unlocked tuck-end. Standard build is 18-24pt SBS in food, pharma, or retail applications. Cost is slightly higher than plain tuck-end (extra glue points); trade-off is tamper-evidence + cleaner presentation.
Available finishes include:
- Lamination: Gloss, matte, soft-touch, or velvet finish for a premium hand-feel.
- Foil stamping: Gold, silver, copper, or custom foil colors for high-visibility brand marks.
- Embossing & debossing: Tactile raised or recessed surface effects on logo or key artwork.
- Spot UV: Selective gloss coating that creates contrast against matte areas.
- Eco-friendly options: Recycled kraft, widely recyclable paperboard and water-based inks.
- Compliance: soy-based inks; child-resistant-style constructions for CBD/cannabis on request.
