Supplier Guide
Verify Folding Carton Suppliers China
Verify China folding carton suppliers by print, die-cut, glue, and sample gates. Shortlist plants before you freeze artwork and volume.
Quick answer
Verify a folding carton supplier by confirming printing, die-cutting, and folder-gluer capability on your board range, plus retained production samples. A hand-cut mockup does not prove color or glue consistency.
What factory evidence matters?
Ask for press types, coating lines, die/tool ownership rules, and recent export references for similar calipers and finishes.
Which specs belong on the audit sheet?
Require board grade codes, color targets, coating maps, glue type, barcode grade, and packing rules. Reject vague “premium color box” claims.
