double corrugated cardboard
Double corrugated cardboard represents a significant advancement in packaging technology, featuring two layers of fluted material sandwiched between three layers of flat linerboard. This innovative structure creates a remarkably robust and versatile packaging material that offers superior protection for heavy or delicate items. The double wall construction provides exceptional compression strength and impact resistance, making it ideal for shipping and storing valuable goods. The material's unique design incorporates air pockets between the fluted layers, which serve as natural shock absorbers and thermal insulators. This construction method also enhances the material's structural integrity, allowing it to maintain its shape and protective properties even under significant stress. The double wall structure typically measures between 6 to 8 millimeters in thickness, providing substantial cushioning while remaining relatively lightweight. These characteristics make it particularly suitable for industrial packaging, overseas shipping, and storage applications where product protection is paramount.
