In short
Seal end boxes are folding cartons whose end flaps are glued shut after filling, giving a secure, tamper-evident closure suited to automated packing lines. Box Sense makes them from 10 boxes, with production in 8–12 business days after proof approval. Shipping is free to any address in the USA.
About our seal end boxes
Cereal boxes, frozen dinners, dry pasta and many over-the-counter products ship in seal end cartons. The flaps are glued closed on a cartoning machine or by hand, so the box cannot be opened without visibly tearing it, and it stands up to distribution better than a tuck carton.
We make seal end cartons to your machine and product specifications, with tear strips or perforations for opening, printed in full color, from 10 boxes.
Seal end options
Choosing the board
| Board | Best for | Notes |
|---|---|---|
| Coated recycled board (CRB) | Cereal and dry foods | Economical, grey back |
| SBS paperboard, 14 to 24 pt | Most retail cartons | Bright white for sharp print |
| Freezer-grade coated board | Frozen and chilled food | Resists moisture and cold |
What affects the price of seal end boxes
Every box is made to order, so each order is quoted individually. These are the things that move the price most, in order:
- Opening features. Tear strips, zipper perforations and pour spouts add tooling and steps.
- Board. Food cartons often use coated recycled board or SBS; freezer-grade board costs more.
- Print coverage. Full-color print with coating is standard; special finishes add cost.
- Quantity. Seal end cartons are usually run in volume, where the unit price is very low.
Send your size, quantity and artwork through the quick quote form for a firm price within 24 hours.
Made for machines
If the cartons run on a cartoning machine, send us the machine specifications: carton style, flap dimensions, grain direction and any score requirements. We match the dieline to the machine so the cartons feed and glue reliably.
Tamper evidence and opening
- Glued ends show clearly if a box has been opened
- Tear strips and perforations let customers open it cleanly
- Reclose tabs keep cereal-style boxes shut after opening
- Food cartons can carry FDA nutrition labeling on the side panel
How ordering works
- Send your specs. Product size, quantity and artwork (or just a logo). A packaging specialist replies with a firm quote within 24 hours.
- Approve the proof. We send a dieline and a 3D proof so you can see the box before it is made.
- Production. 8–12 business days in our own facility, or 5 days on rush.
- Delivery. Boxes ship flat to you anywhere in the USA, free of charge.
