Frequently Asked Questions
What should be checked before approving a lock cap auto bottom box sample?
Buyers should check product size, product weight, box inner size, board thickness, lock cap tongue length, lock slit width, front panel strength, auto bottom glue area, bottom load support, insert fit, window position, barcode or QR code readability, crease lines, surface finish, and packing method.
Why combine a lock cap top with an auto bottom base?
This structure solves two packaging problems at the same time. The auto bottom helps your packing team set up the box quickly, while the lock cap top helps keep the lid secured during handling.
How much weight can a lock cap auto bottom box hold?
The final load capacity depends on box size, board thickness, glue area, bottom structure, product shape, insert design, and shipping method.
How do I choose the right paperboard thickness?
Material grade, dimensions and performance direction are selected from the approved product, structure, print, packing and route requirements.
What is the difference between auto bottom, straight tuck end, and lock cap auto bottom boxes?
Straight tuck end boxes are simpler and often more cost-effective for lightweight products. Auto bottom boxes set up faster because the bottom is pre-glued. Lock cap auto bottom boxes combine a fast auto bottom with a more secure tongue lock top.
How do you control lock cap tolerance and bottom gluing strength?
We check tongue length, lock slit width, front panel strength, glue area, folding direction, bottom pop-up function, and product weight during sample review.
Can I add inserts or a window to this box?
Yes. We can add paperboard inserts, molded pulp inserts, foam inserts, bottle holders, jar holders, or a clear PET window based on your product and display needs.
Can this structure be used for bottles, jars, candles, or electronics?
Yes. Lock cap auto bottom boxes are often used for heavier bottles, jars, candles, cosmetics, electronics, supplements, and retail kits.
Is it more expensive than a standard tuck box?
Yes, it is usually slightly more expensive than a standard tuck box because the auto bottom requires a precise factory gluing process.
Can FSC-related paper documents be checked?
Documentation or certification scope must be confirmed for the selected material, supplier, production route, intended use and destination.
