Why are 200# Test boxes better than ECT 32?

 

Uline carries the strongest boxes around.

  • All Uline boxes have a "Bursting Strength" of at least 200 pounds per square inch.
  • Bursting Strength is the only measure of box strength you should use.

Look at the "Box Certificate" seal to check what you have:

 

  • Competitors may only use the Edge Crush Test (ECT) to determine box strength.
    • ECT is a less rigorous test that measures stacking strength, not bursting strength.
    • A box with an ECT of 32 may only have a Bursting Strength of 130 to 190 pounds.
  • UPS recommends a box with a bursting strength of at least 200 lbs per sq inch.
  • A 200 lb test box will better survive the punishment of being shipped than an ECT 32 box.
