What Makes or Breaks Tuck-Top Auto Lock Bottom Boxes
The performance of a cardboard carton box depends on board GSM, fold alignment, and interlocking base precision. The bottom flaps lock together to support weight — a poor lock design or incorrect crease depth can lead to instability.
StructureSecure Lock Base with Quick Tuck ClosureThe bottom is pre-glued and auto-locks when the box is opened, forming a strong interlocked base. The top features a front-tuck flap that provides easy closure and repeated use without weakening over time.

Frequently Asked Questions
Get answers to common questions about custom rigid boxes, or visit our Help Centre for further information.What are reverse tuck end (RTE) cardboard boxes?
Reverse Tuck End cardboard boxes feature top and bottom flaps that tuck in the same direction (usually to the back). This closing mechanism gives folding cartons a clean, professional appearance, making them an excellent choice for retail packaging.
How are reverse tuck end boxes different from straight tuck end boxes?
As the name implies, while the top and bottom flaps tuck in the opposite direction in an RTE box, flaps in a straight tuck end box close on the same side, which makes them more suitable and cost-effective for slightly bulkier or heavier products.
Are reverse tuck end cardboard boxes easy to assemble?
Yes! They come pre-glued and ship flat, so you can fold and pack them within seconds without needing tape or staples.
Can reverse tuck end boxes handle heavy items?
RTE boxes and other folding cartons are made with cardstock. They are typically used for individual product packaging where the product volume and weights are low. For heavier and bulkier products, we recommend using corrugated cardboard. You can find out more about corrugated boxes here. (Corrugated Boxes / Mailer boxes landing page link).
Can I add a window cut-out to my reverse tuck end cardboard boxes?
100%!! With our custom cardboard boxes, you can choose from a wide range of customizations, including a die cut or PVC cut-out for increased product visibility.
