Custom Seal End Boxes

PLAN WITH CONFIDENCE Build a Production-Ready Seal End Box Plan

A good seal end box begins with the decisions that affect fit, artwork, packing and production. You do not need to arrive with every technical detail settled. Start with the product, quantity, intended channel and brand direction; the service team can help turn those inputs into an approved structure and print plan. The steps below show what to prepare, where decisions connect and which service proofs are available. They also keep timing, quantity and prototype expectations clear before the order moves into production.

1. 
   Start With the Product, Not a Stock Size

   Share the product length, width and height, plus any irregular shape, inner container, wrapping, pack count and intended arrangement. If an insert is needed, include each component and explain how it should be presented or removed. Exact carton dimensions should be developed from these inputs; this page does not invent a standard size or clearance. That process gives the structure and artwork a reliable foundation and reduces the risk of designing an attractive carton around incomplete fit information. For a new product, send the best available measurements and identify which dimensions are fixed. For an existing box, provide the current size and describe what should change. The team can then prepare or adjust the dieline around the approved specification.

2. 
   Match the Structure to Packing and First Access

   Explain how the carton will be filled, which orientation matters, whether the product is a single item or set, and what the customer should see first. Confirm whether the seal end route remains the best fit or whether a tuck end, auto-bottom, lock-bottom, windowed, hang-tab or insert-supported configuration should be quoted instead. This decision is not only technical: it affects which panels carry the main brand message and how the carton is handled at retail, in a handoff or at delivery. Where the chosen format does not support repeated opening, plan the experience around clear first access rather than implying a reclosable use.

3. 
   Choose Material by Character and Use

   Select cardstock, SBS paperboard, kraft or a supported corrugated route according to the product, structural requirement and intended feel. Supported paperboard choices can be quoted in the 14–24 pt range. Coated, matte, glossy or uncoated surfaces are available, and white, kraft or coated interiors can be considered. Corrugated material is available in E-, B-, F- and micro-flute options for suitable mailer, product, promotional, presentation or kit-box applications; it should not be positioned as a large commodity shipping-carton solution. The service team can help connect the material choice to print definition, natural character, tactile restraint or greater physical presence. Ask separately about any certification requirement, because material availability alone does not establish certification.

4. 
   Prepare Artwork Around the Whole Dieline

   Think beyond the front panel. Relevant outside and inside surfaces can carry artwork, including the front, back, top and bottom, subject to the approved dieline and any production areas that must remain clear. Digital, offset and flexographic printing are available, with CMYK, PMS or spot color, full-color printing and white ink on kraft among the supported routes. Finishes may include matte, gloss or soft-touch lamination, spot UV, foil, embossing, debossing, aqueous coating and raised effects. Send AI, PDF, PSD or EPS files where available. Free dieline or template support, artwork checking, resizing, bleed and safe-zone assistance, and design support are available. No die or plate fee applies to the supported job setup. These services help resolve practical file and layout issues before approval.

5. 
   Review the Proof Before Production

   A digital proof is available for every approved order. Use it to review artwork placement, copy, color references, panel orientation and the approved structure before production begins. Printing is not treated as authorized until the required approval and structure confirmation are complete. If a change affects dimensions, an insert or the panel layout, update the dieline and proof together so the package remains one coordinated specification. A physical prototype may be available for a qualifying bulk or wholesale project. Where approved, its cost may be adjusted into the resulting order. This is different from the digital proof; unrestricted free samples and one-box production are not part of the standard offer.

6. 
   Plan Quantity, Timing and Delivery Together

   Paperboard, cardstock, kraft and supported corrugated orders may start from 50 boxes. A low starting quantity can still retain relevant custom sizing, material, exterior or interior print, finish and insert choices, subject to the approved structure and production specification. Per-unit pricing generally improves as quantity rises, with more visible price differences often appearing around 500 units. Ask for quantity levels that match the launch, test, promotion or ongoing program rather than choosing volume on unit price alone. Production normally takes 4–6 business days after payment, final artwork approval and structure confirmation. Production-ready jobs are generally planned to print and ship within 7 business days. Shipping transit time is separate, while complex multi-design orders may require a separately confirmed schedule. Multi-address shipping is available, and design-firm or white-label workflows can also be discussed during quoting. Bring the product measurements, expected quantity, desired material character, artwork status and target use moment to the quote. The service team can then identify the open decisions, prepare the right dieline and confirm the production plan before you commit.
