The Best Price Boxes makes custom auto-bottom boxes with no minimum order, and we beat any written quote for the same specs. An auto-bottom box arrives flat and pre-glued, then pops open with the base already locked, so packing it takes seconds and needs no tape.
How an auto-bottom box is built
The carton is cut and glued flat with the bottom panels attached to the side walls. Open it by pushing the sides apart and the bottom flaps fall into place and interlock. Because the glue joint is made at the factory, you skip the folding and taping that slow down a regular tuck-bottom or tape-sealed carton. The structure is also called crash-lock, snap-lock, or one-touch bottom, depending on the supplier, and those names overlap heavily. We list a snap-lock style separately, so if you are unsure which you need, send a sketch and we will match it.
When it is the right call
Auto-bottom boxes make sense when many units are packed by hand and speed matters: cosmetics, supplements, food items, candles, small bottles, and counter-display cartons. Retailers also like the clean, printed look. For heavy items the base takes the weight alone, so we size the board to the load. If the contents are heavy, a corrugated carton may be the safer pick. Look at custom corrugated boxes for shipping and mailer boxes for single-item ecommerce orders.
How to measure for one
Measure the product on all three axes at its largest points. Write the numbers as length, width, height, and add a few millimeters of clearance so the product loads easily. If you plan to stack inserts, dividers, or tissue, measure the full packed bundle. Auto-bottom styles lock from the bottom, so tall, narrow products need a wider footprint or stronger board to stay stable once filled. When in doubt, send us the product and the weight and we will size the carton.

Questions buyers ask
What is an auto-bottom box?
It is a pre-glued carton that ships flat and locks its own base when you open it. There is no folding or taping. It is a good fit when you pack many units by hand and want speed.
Is an auto-bottom box the same as a snap-lock box?
Often yes. Suppliers use the terms loosely, along with crash-lock. The structures are closely related, so send us a sketch or sample and we will confirm the exact style for your quote.
Can I order a single auto-bottom box?
Yes. We have no minimum order, so a prototype is quoted the same way as a production run. We send a dieline for your approval first.
How heavy a product can an auto-bottom box carry?
Light to medium products are the usual range. Heavy items load the locked base, so tell us the weight and we will specify stronger board or suggest a corrugated carton instead.
Will you beat another supplier’s quote?
Yes. Send a written quote for the same size, board, quantity, and print, and we will beat it.
