Custom packaging production starts with a construction, not a logo file. A dieline is the flat cutting template that shows where a package is trimmed, creased, folded, and glued. The working file ties that template to the product's inside dimensions, board or film direction, artwork, finish map, packing method, and delivery destination. Leave one input vague and a quote can describe a package that is hard to assemble.
What happens between a packaging idea and a packed order?
The working sequence is specification, prepress, proofing, printing, conversion, finishing, packing, and delivery planning. Prepress is the file check before print: trim, bleed, safe areas, folds, scores, glue tabs, panel order, and artwork orientation all need a place. A production note should name the actual construction, not just the product category.
| Production checkpoint | Common industry reference | What to confirm |
|---|---|---|
| Dimensions | Length x width x depth, with inside measurements labeled | Product fit and closure clearance |
| Paperboard | SBS, C1S, or C2S, 12 to 24 pt | Stiffness and printed surface |
| Rigid wrap | Chipboard, 1.5 to 3 mm, wrapped in 100 to 157 gsm art paper | Tray, lid, and wrap alignment |
| Corrugated | E, B, or C flute, with 32 ECT as a common reference | Packed size and handling assumptions |
| Print and finish | Offset CMYK, digital printing, lamination, or selected effects | Coverage and treatment zones |
What needs to be locked before the file goes to press?
Product orientation, finished dimensions, board or film direction, panel order, closure, insert plan, and finish map belong in the brief before artwork is released. Write dimensions as length x width x depth, and label inside and outside measurements. The inside size controls fit. The outside size controls how the finished package nests, packs, and ships.
Keep important type away from scores, trim, and glue tabs. Bleed belongs outside the cut line, while safe areas protect copy from a fold or rough trim. An insert cut to the exact product size can hold too tightly or let the item move when the product and board are not perfectly matched.
How do board and flute choices change conversion?
Paperboard, corrugated board, and rigid board each change the conversion work. SBS, C1S, and C2S paperboard commonly fall in the 12 to 24 pt range. Kraft board commonly falls in the 18 to 24 pt range. A rigid box uses chipboard in the 1.5 to 3 mm range wrapped with 100 to 157 gsm art paper, so the wrap, tray, lid, and alignment need their own assembly checks.
Corrugated flute changes the board profile. E flute has a finer profile and suits tighter printed detail, B flute is thicker, and C flute has a larger profile. 32 ECT is a common industry strength reference. These are material references, not a substitute for checking the packed product and finished structure.
Which print process belongs on the package?
Offset CMYK is a common choice for detailed paperboard graphics, while digital printing fits short runs or artwork versions that still need changes. Flexographic printing is commonly used on corrugated surfaces. Print coverage, artwork detail, board, quantity, and finish belong in the same decision. A press check should look at color, small type, barcode quiet zones, and solid areas that cross scores or glue flaps.
Matte or gloss lamination changes surface appearance. Soft-touch changes hand feel. Spot UV, foil stamping, embossing, and debossing mark specific areas of the finished package. Put each treatment on the finish map so the proof shows which panels carry it.
What does a conversion check look like?
The assembled box is the real conversion check. Compare the cut line, crease depth, folding order, glue area, closure, and finished edges with the dieline. Straight tuck end and reverse tuck end cartons open from different panels. Auto-lock bottom and crash-lock structures change the base setup. A roll end tuck top mailer, commonly referenced as FEFCO 0427, needs an opening and closing sequence that works with the packed product.
Check inserts inside the closed package. An insert can shift the product, change the opening motion, or push the outside dimensions beyond the original drawing.
What should a digital proof show?
The artwork needs to sit on the final dieline with trim, bleed, safe areas, panel order, orientation, and finish locations visible. The barcode quiet zone is the blank space around the code, and it needs to remain clear. Check logo position, folds, scores, glue tabs, closure panels, and insert contact points before approval.
Window patching is another construction line. PET around 0.2 to 0.3 mm is a common general reference for a clear window. The proof should show the opening, the board left around it, and the glue area. A clear panel that looks centered on a flat sheet can sit too close to a fold once the package is made.
Which catalog formats make the brief concrete?
Catalog formats put different production questions on the table. Custom tin packaging brings a metal container and its own decoration and closure decisions. Custom taper candle packaging puts length, protection, and internal clearance first. Custom stevia packaging is a compact carton reference with limited panel space. Custom screw packaging and custom scissor packaging show how product geometry drives cutouts, inserts, and opening direction.
What belongs in a written quote?
A usable quote names the product, labeled dimensions, material, caliper or flute, structure, print coverage, finish, insert or window needs, quantity, tooling, delivery destination and scope, and artwork status. If the product may touch food, ask us about food-contact options for your product. A written list keeps the quote tied to the construction that will be proofed.
Custom Packaging Lane quotes custom packaging production to a 100-unit minimum. Pricing is from $0.49 per unit at volume, quoted to spec. Production is typically 8 to 10 business days after proof approval, plus delivery. Free design support includes a free dieline, and free US shipping is available. The $19.99 sample kit is credited to the first order. Start with custom packaging solutions when the specification is ready.
Frequently Asked Questions
What is a dieline?
A dieline is the flat cutting template for a package. It shows trim, bleed, scores, folds, glue tabs, panel order, and artwork orientation before the sheet is converted. A useful dieline also separates inside dimensions from outside dimensions, marks closure panels, and shows where an insert or window sits.
What does prepress check?
Prepress is the file check before printing. It covers trim, bleed, safe areas, panel order, color setup, barcode quiet zones, scores, folds, glue tabs, and finish marks. It also catches type placed too close to a score or artwork that crosses a glue area.
When does flexographic printing fit a package?
Flexographic printing is commonly used on corrugated surfaces, where the board profile and direct-print coverage matter. Offset CMYK is commonly used for detailed paperboard graphics, while digital printing can suit a short run or changing artwork. Compare the process with the board, coverage, detail, and finish.
Why do glue tabs and scores need attention?
Glue tabs define where adhesive holds the package, and scores define where the board folds. If type crosses a score, it can become hard to read after assembly. If a glue tab carries artwork, the art can disappear inside the seam. Mark both areas on the dieline before the proof is approved.
What is a PET window in packaging?
A PET window is a clear film panel patched over an opening in the package. PET around 0.2 to 0.3 mm is a common general reference. The opening needs enough board around it for strength, plus clear space from folds, scores, glue zones, and the product inside.
