Product Overview
Our custom crush-lock bottom folding carton combines efficient assembly with premium branding. The patented crush-lock base snaps into place in seconds — no glue, no tape, no machine setup — dramatically reducing fulfillment labor while maintaining a rigid, flat-bottom structure that stands securely on retail shelves. Manufactured on our KBA 1050 4-color press with Heidelberg 7+1 UV for vibrant CMYK reproduction, each carton features precision hot foil stamping for your metallic logo and soft-touch matte lamination for a luxurious tactile finish. With 10,000 sqm of production space and daily output capacity exceeding 1.7 million boxes, Bincai delivers consistent quality at scale.
