Practical notes on RFQs, gift-box structures, wrap, and in-house converting.
How to write a custom gift-box RFQ to a Longgang converter
A usable RFQ names inner size, structure, board, print/finish map, quantity, and destination. A catalog photo is not a SKU.
Read articleInner size versus outer size on a gift-box RFQ
Longgang plants quote the cavity the product sits in. If you send outer size without saying so, the lid will not fit the bottle.
Read articleWhat to send instead of a blank “make this box”
A dieline, a sample, or a dimensioned sketch. Taishan cuts steel-rule dies in-house after CTP and Heidelberg print — we still need a drawing.
Read articleSample lead time versus production lead time in Longgang
A structure sample is not a container. Heidelberg print, die-cut, wrap, and pack sit on different clocks once the dieline is locked.
Read articleMOQ and tooling on custom boxes — not a catalog carton
Die, magnet jig, and EVA tray are program costs. A 500-piece folding carton and a 500-piece MDF book box are not the same factory conversation.
Read articleFolding rigid versus lid-and-base versus MDF — pick the structure first
Collapsible grey-board boxes ship flatter. Lid-and-base and MDF cores present better and cube more. Freight follows the choice.
Read articleGrey-board cores, wrap sheets, foil, and UV
1.5–3 mm grey board carries the wrap. Foil and UV sit on the printed sheet according to the finish map — not as a JPEG filter.
Read articleFoil, spot UV, and lamination — write a finish map
Each finish is a pass and a registration risk. Taishan can foil, UV, and laminate wrap sheets. The RFQ must say where.
Read articleMagnetic closures versus ribbon closures on gift boxes
A magnet is a hardware spec. A ribbon is a convert spec. Mixing them on a book-style RFQ without saying which face they sit on wastes a sample.
Read articleRibbon-handle and triangle-handle folding carriers
A handle is a load path. Catalog triangle handles and ribbon totes are gift carriers, not corrugated mailers unless you say so.
Read articleEVA insert versus paper tray versus flocked wrap
The insert sets the cavity more than the outer wrap colour. Lined and flocked catalog boxes are wrap options, not a foam grade.
Read articleBook-style boxes: spine print, magnet, and wrap family
Specialty paper, holographic, printed, and red presentation wraps in the catalog are families. Spine width follows the cavity, not the Photoshop mock-up.
Read articleLid-and-base fit: snug, loose, and two-tone lids
Heaven-and-earth boxes fail in the buyer’s hand when the lid fights the base. Two-tone, lined, plain, and flocked wraps do not change that geometry.
Read articleHeptagon (seven-panel) folding gift boxes and tooling
七菱板 is a collapsible seven-panel rigid, not a round box with extra creases. Open, pink, and kraft catalog cases still need a dieline.
Read articleWhy collapsible rigid boxes change the freight cube
A wrapped grey-board gift box that folds is still a gift box. It is not an SBS sleeve. It does ship flatter than a glued lid-and-base.
Read articleWhen to specify MDF cores instead of grey board
Catalog MDF runs 1.5–7 mm. It is for lid stiffness and weight, not for a cheaper rigid look. Same dieline, different factory path.
Read articleFan, star, and round gift boxes — special-shape converting
Seasonal shapes are dies and hand-assembly time. Catalog fan, star, and round cases are geometry families, not SKUs with a barcode.
Read articleSBS folding cartons, windows, and counter displays
Stationery, toys, masks, and hang-sell SKUs need dielines — not a rigid gift box. Window sleeves and counter displays are converting, not wrap.
Read articleLitho-lam versus direct print on corrugated gift and mailer boxes
Handled gift packs, fruit mailers, and retail mailers in the catalog can be offset or litho-lam. The RFQ must pick a print path.
Read articleWindow cartons: PET versus PP, and what a hang-tab is not
A window patch is a film spec. A PVC hang-tab box is a different converting stream. Do not write “clear window” and expect us to pick the polymer.
Read articlePaper tube gift cans: diameter, height, and lid type
Short and tall straight-wall cans in the catalog are formats. Diameter, height, lid, and liner still come from the RFQ — especially for supplements.
Read articlePVC display boxes: gauge, print, and hang-tab retail
Printed supplement boxes, clear hang-tab boxes, and printed accessory boxes are three catalog cases. Gauge and hang-tab geometry are not optional footnotes.
Read articleHeidelberg offset, Kodak CTP, and post-press in one Longgang plant
8-open, XL-75, and CDX102 lines print cartons and wrap sheets. Die-cut, lamination, and folder-gluer finish the pack. That is the catalog machine list — not a rented press story.
Read articleContract colour: digital mock-up versus Heidelberg production sheet
A screen JPEG is not a press OK. Spot colours, foil, and holographic wrap will not match a social-media render. Ask for a printed sheet.
Read articleExport packing: inner box, master carton, and pallet notes
Gift boxes leave Longgang in export cartons. Corner crush, mix-SKU packing, and pallet height are RFQ lines — not afterthoughts at the dock.
Read articleFSC and other catalog marks — request the current scan
The plant catalog shows FSC, a quality system, high-tech enterprise, and a printing license. Those marks are not a contract until the certificate on the RFQ matches the claim.
Read articleDomestic pharma and food packaging as reference — not a certificate dump
The catalog cites pharmaceutical and food packaging programs plus FSC and a printing license. Ask for the current scan. Do not treat a portfolio photo as a migration test.
Read articleFood gift boxes: liner, contact, and what wrap paper is not
A chocolate rigid box is often paper around food, not a food-contact certificate. If the insert touches the product, say so and request the declaration — do not copy a catalog adjective.
Read articleSourcing a converter in Longgang, Wenzhou — what Taishan actually is
Founded 2000, 20,000+ m², 200+ people, Cendong Road 187–239. A cluster address is not a trading company story. RFQs still need a dieline.
Read articleImporting custom gift boxes from Wenzhou into Southeast Asia
Humidity, cube, and labelling differ by market. A Longgang collapsible rigid that works in a dry warehouse can warp in a port-side store if you skip the wrap spec.
Read articleSourcing rigid gift boxes for the Spanish-speaking market
ES copy on this site is for buyers who quote in Spanish. The millimetres and the board still win. Do not send only a mood-board PDF in English and expect a Spanish carton panel.
