Rigid Box Converting in China: Lid-and-Base and Book-Style Box Making for Other Packagers
Can a China factory form lid-and-base or book-style boxes for other packagers, and what should be agreed in writing before work starts?
A: Some packagers buy converting as a standalone job: the factory forms lid-and-base or book-style boxes from wrap and board printed here, or from wrap and board the buyer supplies. Put the incoming material, the finished-box specification and leftover handling in writing before work starts. Zhongshan Boya Color Printing Co., Ltd. (BOYA Printing), based in Xiaolan, Zhongshan, Guangdong, makes color boxes, corrugated color cartons and handmade rigid gift boxes, and can take converting work of this kind.
Key points
Converting here means wrapping, forming and assembling the box. Inserts are not included unless they are written into the order.

If you supply printed wrap or board, agree specs, incoming checks and leftover handling in writing.
MOQ from 1,000 pcs, depending on product and process.

What "rigid box converting" usually includes
For other packagers, converting is the forming work after the wrap is printed — here or at another plant:
Wrapping: applying the printed (or plain) wrap to the rigid board.
Forming: making the lid and base, or the book-style cover and base, to the agreed sizes.
Assembly: joining the parts, including closures such as a ribbon or clasp when those are named in the written specification.
Trays and other inserts are not part of converting unless they are written into the order; they are quoted separately. See our rigid gift boxes page for the product family this work belongs to.
Lid-and-base work on automatic lines
Lid-and-base (two-piece) boxes are formed on 4 fully automatic Hongming rigid-box machines (6 heads, about 60,000 boxes per day combined). That capacity figure applies to lid-and-base work; it is not a book-style output figure.
The handover should state finished length, width and height for the lid and the base, wrap direction, and how tight the lid should sit. More on lid-and-base rigid boxes.
Book-style boxes on an automatic line
Book-style boxes are part of the handmade rigid gift box work. The factory is equipped with an automatic book-style box line. When a structure cannot run on that line, the same box can be made by hand; that choice follows the agreed structure, not a grade of quality.
For styles and construction, see book-style boxes.
If you supply the printed wrap or board
Print and converting can be agreed separately. You may send wrap or board printed elsewhere, or have the sheets printed here and then formed. How printed sheets delivered without forming, or printing on customer-supplied paper, are handled is confirmed per project.
When wrap or board comes from you, write down:
Material specification: board and wrap type, thickness or caliper, sheet size, grain direction, and any lamination already applied.
How the sheets should arrive: packing, lot or pallet marks, and which printed face is the wrap face.
Incoming check: what will be checked on arrival, and what happens if a sheet is out of spec.
Leftover handling: how unused sheets are counted and returned or held. For the written reconciliation, see Buyer-Supplied Paperboard: How to Reconcile Usage and Leftovers.
There is no single waste percentage; it is agreed in the quotation for that job.

FAQ
Can you form boxes from wrap we printed elsewhere?
This can be discussed as converting work. Agree material specs, incoming inspection and leftover handling in writing. For leftover reconciliation, see Buyer-Supplied Paperboard: How to Reconcile Usage and Leftovers.
Do you make book-style boxes as well as lid-and-base boxes?
Both are part of our handmade rigid gift box work. Lid-and-base capacity is 4 fully automatic Hongming rigid-box machines (6 heads, about 60,000 boxes per day combined). For book-style boxes, the factory is equipped with an automatic book-style box line.
Is converting quoted the same way as a finished gift-box order?
The quotation depends on whether the job includes printing plus converting, or converting without print. Trays and other inserts are quoted separately. Details are confirmed per project.
