China is the world's largest producer of industrial and consumer packaging — corrugated boxes, rigid gift boxes, paper bags, flexible packaging, and speciality formats. The concentration of packaging manufacturers in Dongguan, Shenzhen, and Guangzhou makes the GBA the primary source for brands requiring high-quality printed packaging with short lead times. Here is what buyers need to know before sourcing.
Packaging Categories and What Each Involves
Corrugated and Shipping Cartons
The most volume-driven category. Corrugated board is graded by flute type (A, B, C, E, F flute — thicker to thinner) and wall construction (single-wall, double-wall, triple-wall). For export shipping cartons, double-wall B/C flute is standard for most product weights. Edge crush test (ECT) and bursting strength (Mullen test) are the key structural parameters — specify these, not just "good quality cartons."
Rigid Gift Boxes
Rigid boxes (greyboard construction, covered in paper or fabric) are used for premium consumer products — electronics, cosmetics, spirits, jewellery. Moq is typically 500–2,000 units for custom sizes with printed or embossed lids. Lead time is 25–40 days including tooling for custom inserts.
Paper Bags
Retail paper bags with twisted, flat, or ribbon handles. Specify paper weight (gsm), handle type and attachment method, and whether the bag requires certification (FSC for paper sourcing, food-safe certification if used for food retail).
Flexible Packaging
Pouches, sachets, and flexible films for food, cosmetics, and industrial products. This sub-category requires food-contact compliance (FDA, EU Reg 10/2011) for any food or cosmetic application — confirm the factory's laminate materials are food-grade certified.
Print Processes and What They Cost
| Process | Best For | Cost Implication |
|---|---|---|
| Offset lithography | High-volume, photographic quality, flat sheets | Low per-unit at volume; high setup cost |
| Digital print | Low-volume, variable data, short runs | Higher per-unit; no setup cost |
| Flexography | Corrugated, flexible packaging, long runs | Low per-unit; medium setup |
| Screen print | Fabric bags, specialty substrates | Medium per-unit; colour-limited |
Finishing options — foil stamping, embossing, debossing, soft-touch lamination, UV spot varnish — each add cost but significantly elevate premium packaging perception. Quote each finish element separately to understand cost drivers.
Lead Time Reality
Custom packaging lead times from GBA factories: 15–20 working days for standard corrugated cartons with simple print; 25–35 working days for rigid boxes with custom inserts; 30–45 working days for highly customised packaging with multiple finish treatments. Add 10–14 days for sea freight to most Western markets. Plan packaging procurement well ahead of product production completion.
