Product Overview
Bincai’s corrugated fresh produce shipper is engineered for the demanding cold-chain export market — where ventilation, humidity control, and stack strength determine whether a shipment of premium table grapes arrives in retail-ready condition or as a total loss. B-flute single-wall corrugated construction with strategic die-cut ventilation holes on all four side panels plus top and bottom enables natural convection airflow around the produce. A moisture-resistant coating prevents box degradation in high-humidity cold storage (85–95% RH), while interlocking top tabs provide stack stability without tape or strapping. Manufactured on KBA 1050 4-color offset presses with precision die-cutting in our 18,000 sqm Foshan facility. 22 years of industrial packaging expertise.
