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 converting spec. Mixing them on a book-style RFQ without saying which face they sit on wastes a sample. Taishan samples the closure you name, not a mixed nickname.
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. Write the kilograms and the fold, not a shopping-bag nickname.
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. Send the object or millimetres before we cut a well.
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. Magnet and spine are two specs on one book.
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. Write how it should feel, then sample the core you will buy.
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. Do not send a tube drawing and call it heptagon.
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. Ask the quote how it packs — do not invent a container count from a photo.
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. Pick one core for the sample; do not write “you choose.”
Read articleFan, star, and round gift boxes — special-shape converting
Seasonal fan, star, and round gift boxes are dies, wrap grain, and hand-assembly time at the Longgang plant — catalog silhouettes, not barcode SKUs.
Read articleSBS folding cartons, windows, and counter displays
Stationery, toys, masks, and hang-sell SKUs need SBS dielines at the Longgang plant — folding cartons and counter displays, not a wrapped rigid gift box.
Read articleLitho-lam versus direct print on corrugated gift and mailer boxes
Handled gift packs, fruit mailers, and retail mailers from the Longgang catalog can be litho-lam or direct print — the RFQ must pick the path, not a pretty liner photo.
Read articleWindow cartons: PET versus PP, and what a hang-tab is not
A window patch is a film spec for destination confirmation. A PVC hang-tab box is a different Longgang converting stream — “clear window” does not pick the polymer.
Read articlePaper tube gift cans: diameter, height, and lid type
Short and tall straight-wall cans in the Longgang catalog are format families. Diameter, height, lid type, and liner still come from the RFQ — especially for supplements and tea.
Read articlePVC display boxes: gauge, print, and hang-tab retail
Printed supplement boxes, clear hang-tab boxes, and printed accessory boxes are three Longgang catalog cases. PVC gauge and hang-tab geometry are separate RFQ lines, not footnotes.
Read articleHeidelberg offset, Kodak CTP, and post-press in one Longgang plant
Catalog Heidelberg lines (8-open 4/5, XL-75 4/5, CDX102 4/5/6) print carton and wrap sheets in Longgang. Die-cut, lamination, and folder-gluer finish the pack — not a rented-press story.
Read articleContract colour: digital mock-up versus Heidelberg production sheet
A screen JPEG is not a press OK at the Longgang plant. Spot colours, foil, and holographic wrap will not match a social-media render — ask which proof is contractual.
Read articleExport packing: inner box, master carton, and pallet notes
Gift boxes leave Longgang in export cartons. Inner count, mix-SKU packing, corner crush, and pallet height belong on the RFQ — not as dock-side afterthoughts after the lot is already converted.
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 current certificate scan on this RFQ matches the claim you need on the pack.
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. Treat portfolio photos as structure references — not a migration test and not a license you can transfer onto an export SKU.
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 current declaration — do not copy a catalog adjective onto the purchase order.
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 a manufacturing address, not a trading-company story. RFQs still need a dieline, millimetres, and a destination.
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. Name the destination country — do not treat “SEA” as one climate.
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 — and do not expect a Madrid warehouse SKU from a Longgang plant.
