This format pairs two useful features: a glued seal-end top and an auto-locking base that forms as the flat box is opened out. The auto bottom means assembly is quick, with the base snapping into shape rather than being folded panel by panel, which helps when packing heavier products at speed. The glued top then closes the carton securely once filled.
Base strength for weight
The auto bottom is designed to carry load, so it suits products heavier than a standard tuck-end carton would comfortably hold. The internal size should match the product so it sits firmly, and the base specification should reflect how heavy the contents are. A sample confirms the base holds the weight in practice.
Points to confirm
- Internal size matched to the product weight
- Auto-locking base for quick assembly
- Glued seal-end top for a secure close
- Made to your custom size from a minimum of 100 units
For lines that vary in weight, it is worth agreeing the base specification against the heaviest product so the same carton style holds securely across the range.
