Custom Packaging Boxes for Printed Paperboard and Cardstock Folding Cartons
SunTop Printing manufactures custom packaging boxes for printed paperboard and cardstock folding carton projects inside its Shenzhen printing and packaging facility, where printed color, box structure, finish registration, folding, gluing, and multi-SKU consistency are managed as one production order.
Custom printed boxes move from printed sheet preparation into die-cutting, creasing, folding, locking, and gluing.
The printed paperboard or cardstock is formed into a folding carton with defined crease lines, controlled closure structure, glued seam position, and formed carton geometry across the ordered batch.
For brand packaging, product series, and repeat custom box orders, SunTop connects printed color, paperboard structure, finish position, folding-carton forming, and automatic folding-gluing through in-house folding carton production before the order moves into batch manufacturing.

Custom Printed Paperboard and Cardstock Boxes
SunTop produces custom printed paperboard boxes and custom printed cardstock boxes as single-layer printed folding cartons for branded packaging projects.
For each custom printed box, the selected paperboard or cardstock, printed artwork, carton structure, crease response, folding behavior, locking style, and glued seam position define the finished folding carton.
Board grade, caliper, stiffness, grain direction, unfolded size, and box form set the material and structural basis for each custom printed box and formed folding carton structure.
Custom Printed Paperboard Boxes
Custom printed paperboard boxes use board grades such as SBS, C1S, FBB, CCNB, white-back paperboard, and related paperboard options selected for printed surface behavior, board stiffness, crease response, folded shape, and formed carton structure.
Custom Printed Cardstock Boxes
Custom printed cardstock boxes use cardstock grades for lighter folding carton formats where print coverage, crease response, folding rebound, closure fit, and glued seam position define the formed carton structure.
Printed Folding Carton Structures
Printed folding carton structures can include straight tuck end boxes, reverse tuck end boxes, auto-lock bottom boxes, tuck boxes, and related folding carton formats where the dieline, crease lines, locking structure, and glued seams are built around the printed artwork layout.
Board Grades and Box Forms
Common custom box projects often use board ranges around 14pt–24pt or approximately 250–450gsm, with board choice set by box size, paperboard stiffness, folded shape, closure structure, finish, and batch consistency.
Printed Color Across Custom Packaging Boxes
Printed color on custom packaging boxes is controlled from approved artwork to the press sheet and then to the formed box faces after folding and gluing.
For custom printed boxes, Pantone targets, CMYK artwork, large solid color areas, halftone graphics, paperboard surface, ink density, and multi-color registration set the color-control basis for the printed box faces.
SunTop Printing uses G7 Master color management, ISO 12647 printing standard, Pantone color control, Heidelberg CTP plate output, Heidelberg Speedmaster multi-color offset printing, production color records, Lab value records, and Delta-E batch color control to keep printed color consistent across custom packaging box orders.
For multi-SKU packaging and repeat custom box orders, color records and batch color control align related printed paperboard and cardstock boxes with the approved Pantone / CMYK color targets across the series.
Pantone and CMYK Color on Printed Box Faces
Pantone colors, CMYK values, brand graphics, and large solid color areas are prepared for the printed box faces that remain visible after die-cutting, creasing, folding, and gluing.
Heidelberg CTP and Multi-Color Offset Printing
Heidelberg CTP plate output and Heidelberg Speedmaster multi-color offset printing support accurate plate preparation, stable color transfer, and repeatable printed color during batch production.
Large Solid Color Areas and Ink Density
Large solid color areas are managed through stable ink density, even ink laydown, and production color control to keep the ordered batch within the approved color range.
Lab Records and Delta-E ≤ 1.0 Batch Color
Lab value records, production color records, and Delta-E ≤ 1.0 batch color control support repeat orders and multi-SKU packaging series where printed color must stay consistent across related paperboard and cardstock boxes.
Die-Cutting, Creasing, Folding, and Gluing
After printing, the printed paperboard or cardstock sheet is converted into a formed folding carton through die-cutting, creasing, folding, locking, and gluing.
Die-cutting accuracy sets the box outline and structural position. Creasing defines fold lines, crease depth, and board response. Folding rebound, crease line stress, and crease line crack prevention guide folded-edge stress, formed carton structure, and box squareness during forming.
In batch production, closure tabs, side-locks, glued seams, box squareness, and folding response work as one formed-carton structure during packing, handling, repeat production, and automatic cartoning line use.
SunTop connects die-cutting, creasing, folding, and automatic folding-gluing so custom printed paperboard and cardstock boxes can maintain folded shape, closure tab engagement, lock position, glued seam position, and formed carton consistency across production quantities.
Die-Cutting and Creasing Accuracy
Precision die-cutting and creasing align the printed artwork, box outline, crease lines, closure areas, and glued seam positions before the sheet becomes a formed folding carton.
Folding Rebound and Crack Prevention
Board stiffness, grain direction, crease pressure, and folding rebound define folded-edge response. Crease line crack prevention controls cracking risk, crease-line stress, and folded-edge surface continuity on paperboard and cardstock boxes.
Locking Structure and Glued Seam Strength
Closure tab engagement, side-lock position, folder-gluer guide tolerance, glued seam strength, and glued seam positioning tolerance within ±0.5mm align lock position, closure fit, and glued seam position during packing, handling, and repeat production.
Automatic Cartoning Line Stability
For custom packaging boxes used with automated packing, box squareness, opening behavior, folded shape, lock position, and glued seam consistency support feeding, opening, closing, and automatic cartoning line stability.
Finish Position and Registration on Formed Custom Boxes
For custom packaging boxes, foil, UV, embossing, debossing, and lamination are planned around both the printed sheet and the formed folding carton.
Finish areas are aligned with printed box faces, fold lines, artwork position, and formed carton geometry.
SunTop Printing uses plate-making, print positioning, dieline, and crease references to set finish position before the carton is formed. During press positioning, the side guide and gripper edge serve as sheet-position references for printed panels, finish areas, die-cut shape, and folded carton structure on the same press sheet.
When foil, UV, embossing, debossing, or soft-touch lamination is used on printed paperboard and cardstock boxes, finish position, registration, adhesion, abrasion resistance, and surface stability are matched to the formed carton structure.
Foil, UV, and Embossing Position on Formed Boxes
Foil, UV, embossing, and debossing areas are positioned against the printed panels, dieline reference, and crease reference to maintain finish registration after die-cutting, creasing, folding, and gluing.
Surface Adhesion and Abrasion Resistance
Surface finish needs stable adhesion and abrasion resistance after forming, especially when custom printed boxes use foil areas, UV contrast, embossed details, debossed details, or soft-touch lamination on folded paperboard surfaces.
Multi-SKU and Repeat Order Consistency
Custom packaging box programs often include related SKU versions, artwork versions, product sizes, color variations, and later repeat orders.
Multi-SKU packaging series and repeat custom box orders extend consistency beyond one printing run. Printed color, artwork position, folded size, formed box size, finish position, lock position, and glued seam position stay comparable across related custom printed boxes.
SunTop uses production log data recall and production retain sample comparison with approved print proofs, standard color samples, structural samples, color records, and dieline records as repeat-order production references.
Approved print proofs, standard color samples, structural samples, color records, and dieline records connect printed color direction, artwork position, folded size, formed box size, finish position, lock position, and glued seam position across related SKU versions and repeat batches.
Multi-SKU Box Version Matching
Related custom printed boxes are checked against approved print proofs, standard color samples, structural samples, color records, and dieline records so printed color direction, artwork position, formed box size, finish position, lock position, and glued seam position stay aligned across the brand series.
Repeat Order Sample and Record Comparison
Production log data recall and production retain sample comparison are used as the repeat-order production basis, helping folded size, formed box size, finish position, lock position, and glued seam position stay aligned from batch to batch.
