For sea freight export packaging of large construction machinery, 25mm 9-layer full birch core plywood is customized to manufacture heavy-duty equipment packaging cases.

This plywood is processed through high-pressure lamination, waterproof and anti-corrosion treatment, featuring high structural strength and strong load-bearing capacity. A single case can stably hold heavy machinery equipment weighing up to 12 tons. The panels offer excellent impact resistance, compression resistance and moisture-proof performance, capable of withstanding jolting, extrusion and high-humidity salt spray environments during ocean transportation, so as to effectively protect precision mechanical parts from damage.

Meanwhile, the plywood meets import and export non-fumigation standards without additional quarantine procedures, greatly simplifying export customs clearance. It is widely used in cross-border logistics packaging for construction machinery, precision instruments and large electromechanical equipment.
