Custom Seal End Boxes

Seal end boxes are folding cartons that use a sealed end closure rather than relying on tuck flaps at every end. The construction has connected panels, a seam, score lines, and an end that is closed during the approved packaging process. Teal Packaging quotes the sealed end, any opening tuck, board direction, artwork, finish, quantity, and packing sequence as one specification.

Seal end carton and FOSE are terms that may appear in a packaging brief for this family. The label alone does not define a fixed board, size, glue pattern, or filling method. Send the product, closure access, panel plan, and intended packing workflow so the dieline represents the actual carton.

Panel and seal layout

A seal end carton uses front, back, and side panels connected by score lines and a joining seam. One end is arranged for a sealed closure. The other end may use a tuck or another approved access method, depending on the package brief. The end construction, glue area, and panel orientation need to be visible in the dieline.

• Front panel for primary identity, product copy, and approved artwork.
• Back panel for instructions, required information, or supporting design.
• Side panels for secondary copy, graphics, or a coordinated treatment.
• Sealed end panels with the approved closure and glue area.
• Access end, tuck flap, seam, and scores shown in the packaging proof.

Panel geometry depends on product fit and material. A window, insert, or die-cut is a separate request that should be reviewed against the seal area and any opening flap. Teal can review those additions by specification.

Closure and assembly

The sealed end is formed by folding the end panels and joining the approved glue areas. The other end stays available for the planned product access until the package is filled and closed. The quote should identify which end is sealed, which end is used for loading, and whether the box is supplied for hand packing or another defined workflow.

A seal end construction may be considered when an end needs a closed carton condition after packing. That does not mean every seal end box follows the same filling or line process. State the intended workflow and any equipment interface in the brief, then review the sequence in the quote. Teal does not add machinery claims or a filling assumption that is not provided.

Material and print selection

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 helps frame the print discussion. A smaller run can use a concentrated panel plan and a finish selected for close proof review. A larger run can support coordinated panels, variants, or a more detailed finish map. Quantity does not set a material grade, print process, or glue method. Those decisions follow the supplied artwork and approved packaging scope.

• 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 seal end boxes fit

Choose seal end boxes when the package needs a defined sealed end and a controlled access end. The construction can suit a buyer whose product loading sequence ends with a closed carton. It differs from a straight tuck or reverse tuck box because the end treatment is defined by the sealed closure.

Compare auto bottom boxes when a pre-glued bottom that opens into place is the key requirement. Use the broader tuck box family to compare end closures and panel options. Select the style based on the product, packing workflow, and closure requirement rather than the abbreviation alone.

Quantity and production planning

Standard MOQ is 50 units. Pricing depends on material, seal 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. A specific order should not be called 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.

Direct quote requirements

• Product, quantity, fit, and any insert, window, or die-cut.
• Which end is sealed and which end is used to load the product.
• Whether the brief uses seal end carton or FOSE terminology.
• Artwork for front, back, sides, access end, and sealed end panels.
• Material, surface treatment, finish, destination, and target arrival date.

The free dieline should show the sealed end, glue area, seam, scores, opening end, and artwork orientation. Use the digital proof to check the actual fold sequence and ensure that finish areas do not interfere with closure or loading.

Proof checklist

Confirm the seal panels meet in the intended order, the access end opens as planned, and the product can be loaded without an unapproved assumption. Check the glue area, score lines, window or die-cut, and any insert. Review print, foil, debossing, spot UV, and surface treatment on the panels where each treatment is specified.

A factual seal end brief keeps the closure and packing sequence visible. It gives Teal the information needed to quote the carton without claiming an unverified machine process or universal material choice.
