Product Overview
Bincai’s die-cut window folding carton transforms baked goods into showcase pieces. The precision die-cut window — available in any shape from simple rectangles to brand-logo silhouettes — lets customers see the product before purchase, boosting shelf conversion rates by 30–60%. The 0.25mm PET film is optically clear and food-safe, while the 350gsm CCNB (Clay Coated News Back) board provides structural integrity for stacking and transport. Food-grade aqueous coating ensures compliance with FDA indirect food contact standards. Flat-packed for efficient shipping, these cartons assemble in seconds via tuck-flap closures. Manufactured in our Foshan smart factory (18,000 sqm) on Heidelberg 7+1 UV offset and KBA 1050 4-color presses. 220+ skilled workers, 22 years of packaging expertise.
