Color box and mailing box
Cardboard color boxes focus on printing performance, fold line accuracy and retail display; corrugated mailing boxes select flute type and cardboard based on product weight, buffering and distribution path. The two are assessed separately and are not replaced by the same set of pictures or generic instructions.

Book cover and display box
Publishing packages need to check the spine thickness, extraction gap, mounting material, inner support and transportation protection at the same time. The bookcase, clamshell display box and collector's edition are all developed according to the actual book and periodical sizes and do not apply the retail color box structure.
Pit carton and publishing set
The following is a schematic diagram of product structure and application scenarios. It is used to clearly distinguish mailing, retail, transportation protection and publishing packages. It does not replace customer cases or actual factory shots.




Transform materials into performance
The structure, cardboard grade, lamination, inner support, opening and closing method and surface technology are reviewed as a system, so that display and protection can play a role at the same time.
Review the die line, cardboard compensation, opening and closing performance and assembly sequence before proofing.
Matches gray board, white card, cow card and corrugated grades according to product weight, surface effect and circulation conditions.
