Need packaging that is quicker to assemble without compromising the way your product is packed and presented? We manufacture auto lock bottom boxes to your required size, board, printing, finish, and structural specifications.
You can customise the box around your product rather than adjusting your product to a standard carton. Add custom inserts, windows, dividers, handles, or other structural features where they serve a practical purpose. Our packaging team can assist with artwork and structural development, helping you move from an initial idea to a production-ready box.
With no minimum order quantity, free design assistance, sampling support, and custom manufacturing, you can order packaging according to your actual requirements, from a small product launch to a larger production run.

Auto lock bottom boxes are also known as crash lock bottom or auto bottom boxes. These folding cartons have a pre-glued base that locks into position as the box is opened. Instead of manually folding several bottom flaps into place, the base forms and secures itself during setup.
The boxes are supplied flat, which keeps them compact before use. Once opened, the locking bottom creates the base on which the product sits.
The top of the carton can be specified separately according to how you want the product packed and accessed. You can pair the auto-lock base with a tuck top, full flap, or seal-end closure.
This makes the structure different from a standard tuck-end carton. The key feature is not simply the shape of the box, but the way its bottom is engineered to form during assembly.
Auto lock bottom boxes are a practical choice for products that need a secure base and quick carton assembly. They are commonly used for:
The right specification depends on the product weight, dimensions, and how the load sits inside the box. We can adjust the board grade and base specification to suit the product. You can also add custom inserts when extra positioning or protection is required.
The material of an auto lock bottom box needs to do more than hold print. It must crease cleanly, fold accurately, and support the pre-glued bottom as the carton opens into shape.
For lightweight to standard retail products, SBS and white paperboard are commonly used because they provide a smooth print surface while maintaining the stiffness needed for a clean auto-lock structure.
For brands that prefer a natural appearance, kraft paperboard can be used without changing the basic auto-bottom functionality. Its uncoated surface gives the box a more organic look, although printed colours will appear differently than on white board.
For heavier products or boxes with larger sizes, we can specify heavier board grades or suitable fine-flute corrugated material where additional rigidity is required.
The final board choice is based on the product weight, box sizes, print coverage, and the strength required form the auto lock base, rather than using one material specification for every box.
The print and finish should work with the folds, glue areas, and moving panels of the auto-lock structure. We plan artwork around the dieline so important text, logos, and design elements do not sit across creases or interfere with the pre-glued base.
For shorter runs or changing artworks, digital printing is a practical option. For larger quantities or tighter colour consistency, offset printing can be used. Artwork can be produced in CMYK or Pantone colours, with printing on the outside, inside, or both sides of the box.
Finishes can then be selected according to how the carton needs to look and feel. Matte, gloss, and soft-touch lamination change the overall surface, while Spot UV, foil stamping, embossing, and debossing can be used to draw attention to specific branding elements.
Carefully combined printing and finishing can make the box more distinctive on the shelf while reinforcing the quality and positioning of your brand.
Custom box makers never compromise on structural accuracy or box quality. Each auto lock bottom box is customised with the correct dieline, crease placement, glue points, and board grade based on the product load, helping the base form and perform as intended.
Our team helps you get these details right before production, from selecting the suitable board and box dimensions to checking artwork placement.
Having served 2500+ businesses over 6+ years, we have worked with different product sizes, weights, print requirements, and packaging applications. That experience helps us identify specification issues early and recommend a box that is practical to pack, present, and reorder.
You can also get custom sizing, 3D proofing, no minimum order quantity, and free delivery, so you can approve the structure before committing to production

It is usually a good fit when you need faster carton assembly with a pre-glued base. Product weight, box dimensions, and how the load sits inside the carton should still be checked before finalising the structure.
We normally need product dimensions, approximate weight, required size, and intended use to recommend your board grade.
Yes, but compact heavy products can place more concentrated weight on the base. In that case, the board grade, base proportions and internal support need to be specified more carefully.
It can, but important logos, text, and design details should be positioned carefully around creases and glue areas. We plan the artwork against the dieline so the final box looks correct once folded
Yes. Once the size, material, dieline, and artwork are approved, the same specification can be used for repeat production, provided your product and packaging requirements have not changed.
Yes. With no minimum order quantity, you can order a smaller first and scale the quantity later if the specification performs well for your produc
