Heavy-duty corrugated box

제품 상세 정보

Heavy-duty corrugated boxes are high-strength, multi-layer corrugated paper transport packaging, mainly made with double-wall or triple-wall corrugated structures and formed by laminating high ring-crush and high burst-strength kraft linerboard. Compared with ordinary cartons, they offer higher compression strength, greater load-bearing capacity, drop resistance, stacking resistance, and better performance in long-distance transportation. They can partially replace wooden boxes and plastic crates, and are used as outer packaging for heavy, large-sized, and high-stacking cargo. The regular load-bearing range is 100 kg–1,500 kg. They are suitable for the transportation and warehouse stacking of heavy goods such as machinery, hydraulic equipment, auto parts, home appliances, bulk industrial materials, and large-volume food raw materials. Heavy-duty corrugated boxes can be customized with waterproof and moisture-resistant treatment, reinforced corner protection, reinforced steel strapping, and food-contact-grade materials according to specific needs. They comply with domestic transport packaging standards and export commodity inspection requirements. With advantages such as lightweight design, recyclability, environmental friendliness, and circular reuse, they have become a mainstream green alternative for industrial export packaging.
