How to Source Custom Packaging and Printing in China: A Buyer Checklist

A practical buyer checklist for sourcing custom boxes, bags, labels, inserts, and printed packaging in China, covering structure, dimensions, material, artwork, color, finishing, prototypes, packing, and supplier confirmation.

Custom packaging is easy to underestimate because buyers often start with a visual idea: a box photo, a competitor package, or a design mockup. But a useful quotation depends on more than appearance. Structure, internal dimensions, material thickness, printing area, finishing, inserts, assembly, packing method, and artwork preparation can all change the production method and cost. This is a buyer checklist rather than a fixed specification. Final paper, board, film, fabric, thickness, printing, finishing, quantity requirements, and production feasibility should be confirmed with the selected packaging supplier. 1. Start with the product that the packaging must protect or present Before discussing colors and printing, explain what will go inside. Share product dimensions, approximate weight, shape, fragility, number of pieces, and how the package will be used. A retail display box, shipping mailer, gift box, pouch, label, hangtag, sleeve, insert, and shopping bag solve different problems. The supplier needs to know whether the priority is protection, retail presentation, gifting, shipping efficiency, brand appearance, or a combination. 2. Confirm internal dimensions before focusing on external dimensions For boxes and fitted packaging, usable internal space is often more important than the outside measurement. Product length, width, and height Required internal clearance Insert cavity dimensions Lid depth or overlap Bag or pouch usable area Handle position Label or sticker dimensions Shipping-carton constraints if relevant If one package must fit several product sizes, explain the range instead of assuming one box will work for everything. 3. Choose the structure before finalizing artwork The dieline and artwork depend on the physical construction. A rigid gift box, folding carton, corrugated mailer, sleeve, drawer box, magnetic box, paper bag, or pouch uses different panels and production methods. Tuck, lid, drawer, magnetic, self-locking, or another closure Window or no window Handle or no handle Insert or divider Flat-packed or pre-assembled delivery Tear strip, adhesive strip, zipper, or resealable feature where relevant A structural sample or blank prototype can be useful before final artwork is locked. 4. Treat material and thickness as targets, not generic names Terms such as kraft paper, cardboard, corrugated board, greyboard, coated paper, plastic film, non-woven fabric, or cotton do not completely define a package. Base material or board type Paper or board weight/thickness Corrugated flute or construction where relevant Surface coating or lamination Film structure or thickness for flexible packaging Fabric type and weight for reusable bags Required stiffness, flexibility, tear resistance, or protective function Material, thickness, finish, color, and construction shown on a reference package should be treated as a reference configuration. They can often be adjusted around the buyer’s product, appearance, budget, packing, and shipping needs, subject to supplier confirmation. 5. Prepare artwork around the production dieline A visual mockup explains the idea, but final production artwork normally needs to fit the supplier’s confirmed dieline or template. Correct panel size and orientation Bleed and safe areas Fold and cut lines Logo size and position Text size and readability Barcode or QR-code area Required legal, care, warning, origin, recycling, or other information where relevant to the actual product and market Do not finalize critical artwork before structure and dimensions are confirmed. 6. Confirm printing color with an appropriate proof Screen colors are not a reliable final production standard. If specific brand colors matter, provide a clear target and agree how they will be approved. Depending on the process, this may involve a digital proof, printed proof, Pantone reference, material sample, or physical pre-production sample. Evaluate color on the actual material because kraft paper, coated paper, fabric, clear film, and textured surfaces can change the result. 7. Review finishing together with the base material and artwork Matte or gloss lamination Varnish Spot UV Foil stamping Embossing or debossing Texture or specialty paper Soft-touch or another surface treatment Window film, ribbon, magnet, or other decorative components Not every finish works equally well on every material or structure. Confirm the combination with the packaging supplier. 8. Design inserts and internal presentation around the product An insert can control movement, protect surfaces, separate accessories, and improve presentation. Possible materials include paperboard, corrugated board, molded pulp, foam, plastic trays, fabric, or another structure depending on the project. Number of product pieces and accessories Product orientation Removal method Required protection Whether the insert needs printing or branding Any documented material requirement that genuinely applies 9. Plan labels, barcodes, and variable information early Clarify which information is fixed and which changes by product, size, color, batch, marketplace, or destination. Variable labels can be more practical than printing every variation directly onto the main package. 10. Confirm how the finished packaging will be packed and shipped Flat-packed or assembled delivery Protection between printed surfaces Bundling method Export carton quantity Carton dimensions and weight target where important Moisture or edge protection where relevant Whether packaging ships empty or together with the finished product Packaging volume can materially affect freight, so packing method should be considered before the quotation is treated as final. 11. What information helps produce a more useful quotation? Photo, sample, dieline, sketch, product link, or product code Product dimensions and approximate weight Packaging type and opening/closure style Required internal dimensions Approximate quantity Material or thickness target if known Printing artwork or at least the number of print positions/colors Finishing requirements Insert or accessory requirements Barcode, label, or variable-information needs Flat-packed or assembled preference Destination country or market Target price range if you already have one Sample or timing requirement 12. Use a prototype or sample to confirm structure and appearance A digital rendering cannot fully prove fit, opening feel, stiffness, print color, finishing, insert fit, or packing behavior. Review the actual sample against internal fit, dimensions, closure, material feel, print alignment, finishing position, insert fit, labels, and packing method. What to send Benson Sourcing Start with a photo, existing package, sketch, or product link plus the approximate quantity. If possible, include the dimensions and weight of the product that must fit inside. A complete dieline is not required before the first sourcing conversation.
