Practical notes on RFQs, gift-box structures, wrap, and in-house converting.
Foil, 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 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.

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 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.

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.

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.
