Product Overview
Bincai’s crush-lock bottom folding carton is engineered for the premium pet food market — where packaging must perform on shelf, in transit, and through the consumer’s kitchen. The 400gsm FSC-certified SBS (Solid Bleached Sulfate) board delivers crisp white printing surface with crush-lock auto-bottom for rapid hand or machine erection. Matte lamination exterior with spot UV branding accents creates a tactile premium feel, while the food-grade aqueous coating on the interior ensures direct food-contact safety for freeze-dried treats, kibble pouches, and supplement packaging. Manufactured on KBA 1050 4-color offset presses with inline aqueous coating in our 18,000 sqm Foshan facility. 22 years of packaging expertise.
