Paperboard and Protection
Material choice should be based on product weight, carton size, retail display needs, and shipping method.
Inserts and Window Options
Heavier or fragile items often need more than a strong bottom; the product should also be held in place.

Frequently Asked Questions
What are custom full flap auto bottom boxes?
Custom full flap auto bottom boxes are pre-glued folding cartons with a crash lock bottom structure. The bottom pops open during assembly and uses overlapping flaps to provide stronger support for heavier retail products.
Full flap auto bottom vs. snap lock bottom: what is the difference?
Full flap auto bottom boxes are pre-glued and open quickly during packing. They are faster to assemble and provide stronger bottom support for heavier retail items.
How much weight can full flap auto bottom boxes hold?
The suitable weight depends on carton size, paperboard thickness, bottom overlap, product shape, insert design, and export packing method. We recommend testing the structure with your actual product during sampling.
Do these boxes need tape on the bottom?
No. The pre-glued crash lock bottom is designed to lock into place when the carton is opened. For very heavy or fragile items, inserts, partitions, or stronger board combinations may still be recommended.
Can full flap auto bottom boxes be used for glass bottles?
Yes. This structure is commonly used for glass bottles, jars, candles, skincare products, and beverage packs. For fragile glass items, we usually recommend testing board thickness, inserts, and outer carton protection together.
What causes crease cracking on auto bottom cartons?
Crease cracking can happen when thick paperboard, dark solid printing, heavy ink coverage, lamination, or incorrect crease depth is used. We review crease lines and recommend sampling before mass production for premium printed cartons.
Can these boxes be used for food or beverage packaging?
Yes, but food and beverage projects should confirm food-contact paper, inner liner requirements, grease resistance, moisture conditions, and local packaging compliance before production.
What information do you need for a quote?
Please send your item size, item weight, box style, material preference, artwork file, quantity, and delivery country. Our packaging engineers can help prepare a dieline and recommend the right board thickness, bottom structure, insert, finish, and packing method.
