Bincai Corrugated Mailers

Product Overview

Built for the most demanding shipping environments, this heavy-duty double wall corrugated box combines BC-flute strength with full customization to protect your products from warehouse to doorstep. Manufactured by Guangdong Bincai Color Printing — a 22-year packaging enterprise with 18,000 sqm of integrated production space — these boxes are engineered for e-commerce fulfillment, industrial parts distribution, and export freight. Double wall construction (BC or BE flute) delivers superior crush resistance and stacking strength compared to single wall alternatives. With ISTA 1A transit testing available and FBA-compliant sizing, Bincai produces these boxes alongside its 1.7M daily color box output from a dedicated corrugated line within its ISO 9001:2015 and FSC-certified facility.
