Custom Auto Bottom Boxes

Auto bottom boxes are folding cartons with a bottom construction that opens into place and a tuck top for access. The pre-glued bottom, also called a crash lock or auto lock bottom, changes the assembly sequence compared with a carton that uses tuck flaps at both ends. Teal Packaging quotes the bottom construction, panels, top closure, material, artwork, finish, quantity, and packing method together.

The auto bottom name describes the bottom action. It does not define one board choice, one product fit, or one delivery condition. Tell Teal how the box will be packed, which end needs access, and whether the package needs a window, insert, or die-cut. The free dieline and digital proof should show the actual construction.

Panels and bottom construction

An auto bottom carton uses front, back, and side panels joined by score lines and a seam. The bottom panels are arranged and glued so the base opens into a formed bottom. The top generally uses tuck flaps. The final score layout depends on the product, material, panel plan, and the required packing sequence.

• Front panel for the main product identity and primary artwork.
• Back and side panels for supporting copy or coordinated graphics.
• Top tuck closure for access after the product is packed.
• Pre-glued bottom panels that open into the base construction.
• Seam, scores, glue areas, and any die-cut shown in the dieline.

Bottom behavior depends on the approved material and glue construction. Do not assume the box will open into a particular shape or arrive in a particular condition without confirming it in the quote. If the buyer needs a specific packing motion, it should be written as part of the job.

Assembly and packing sequence

The carton is opened and the glued bottom is formed into place. The top tuck remains available for inserting the product and closing the box. The assembly note should state whether the box is erected by hand, supplied in another condition, or used in a repeat packing workflow. Teal quotes the requested scope rather than assigning a filling process by default.

Auto bottom construction changes the bottom assembly sequence an operator follows, but the practical workflow still depends on product fit, material, glue, and quantity. Describe the intended packing sequence and any need for an insert. If the box has a window or a die-cut, confirm how it affects forming and loading.

Materials and print

Material selection follows product fit, fold and score behavior, print surface, handling, and quantity. The approved board option, artwork coverage, and print process must be recorded in the quote.

Run size affects the conversation about print and finishing. A smaller run may use a concentrated panel plan and a finish selected for clear proof review. A larger run may support coordinated exterior panels, variants, or more involved finish mapping. Quantity does not set a material grade or print process. Teal confirms the combination against the actual brief.

• Exterior artwork mapped to approved panels.
• Interior artwork included only when it appears in the quote.
• Print process selected after run size and material review.
• Color and finish requirements recorded in the proof.

When auto bottom boxes fit

Choose auto bottom boxes when the bottom should open into a formed base and the top should remain a tuck closure. This construction can suit a product that needs a formed base during packing or presentation. It is a different choice from a straight tuck or reverse tuck box with tuck closures at both ends.

Compare the family hub at tuck boxes for the broader panel and closure options. Review seal end boxes when the end closure and machine-fill reference in the brief point toward a sealed carton. The product, packing process, and closure requirement should control the choice.

Quantity and route

Standard MOQ is 50 units. Pricing depends on material, bottom construction, print, finish, die-cut, window, quantity, assembly, and route. Teal is a US manufacturer with production facilities in West Chicago, Illinois and Guangzhou. The production manager routes each job to whichever facility fits the specification. Do not describe a specific order as US-produced before routing is confirmed.

Eligible in-house work may run in about 7 business days; specialty imported work may take about 12 weeks; these are planning ranges, not guarantees. Rush production carries a 7-25% premium depending on the job. Free US shipping, free dieline design, and a free digital proof are included in the stated service offer. Confirm the schedule and delivery scope in the quote.

Quote brief

• Product, quantity, fit, and any insert, window, or die-cut.
• Top tuck direction and the desired auto bottom or crash lock construction.
• How the carton will be opened, formed, filled, and closed.
• Artwork for front, back, side, top, and any interior or bottom-facing panel.
• Material, surface treatment, finish, destination, and target arrival date.

Use the free dieline to check the glued bottom, score lines, seam, top tuck, and artwork orientation. Use the digital proof to confirm that the product can be loaded in the planned sequence and that every finish is mapped to the correct panel.

Direct proof checks

Confirm that the bottom opens into the approved base, the top tuck closes cleanly, and the glue area is not covered by required artwork. Check product fit, insert position, window or die-cut placement, and the material named in the quote. Review foil, debossing, spot UV, and surface treatment on each selected panel.

A clear auto bottom specification gives Teal the facts needed to quote the carton and route the work without inventing a packing assumption.
