Product Overview
This heavy-duty corrugated industrial parts shipper is engineered for the most demanding B2B logistics: export-grade machinery components, automotive OEM parts, precision tooling, and industrial equipment that requires absolute protection during international freight. Constructed from BC-flute double-wall corrugated on Guangdong Bincai’s BHS 2.5m Corrugator line, the shipper delivers ECT 44+ lb/in edge crush strength and 275+ psi burst resistance. A custom CNC-cut PE or EPE foam partition system secures each component in its own isolated cavity, while the integrated pallet base enables direct fork-lift handling without secondary palletization. Each shipper is ISTA 3E certified for parcel delivery and LTL freight, and manufactured under ISO 9001:2015 quality management with FSC Chain-of-Custody materials. With 22 years of corrugated manufacturing expertise (founded 2003), Bincai produces 1.7 million boxes daily from an 18,000 sqm integrated facility in Foshan, Guangdong.
