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 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 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 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.

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.
