The Differences

  • Single-wall corrugated boxes have a wide range of material strength, which is measured in terms of the Edge Crush Test (ECT). The ECT test identifies the strength of the corrugated cardboard per square inch when crushed. The ability of the assembled box to withstand weight before bursting is measured with the Mullen Bursting Test. Single-wall corrugated boxes start at 23 ECT and range up to 55 ECT. Most single-wall corrugated boxes come in 200# to 275# bursting test strength. Very lightweight single-wall boxes will have a maximum box weight of 20 lbs., a bursting test weight of 125 lbs., and an ECT of 23 lbs. per square inch.
  • Double-wall cardboard is automatically stronger and more resistant to crushing than single-wall cardboard. Heavier and less flexible than single-wall corrugated material, double-wall corrugated cardboard is designed to accommodate heavier contents for shipping and storage. Double-wall corrugated cardboard strengths range from 42 ECT to 82 ECT. Double-wall corrugated boxes have minimum bursting test weights starting at 200 lbs. and going up to 600 lbs.
  • Triple-wall corrugated boxes contain three corrugated mediums and four linerboard facings. This 7-ply construction is used where large container sizes are involved, such as pallet packs. Triple-wall corrugated boxes can hold significantly more weight, ranging from 240 to 300 lbs., with 67 to 112 ECT. Triple-wall corrugated boxes are the heaviest type, and can hold significantly more weight, ranging from 240 to 300 lbs., with 67 to 112 ECT. Click here to learn about the different types of fluting.
