Which box is right for me to use for packaging? This box guide will help provide the answer.


200 lb. Test or 32 ECT Boxes? What’s the difference?

  • Eliminate costly returns due to shipping damage. Choosing an incompatible cardboard box for a desired shipping or packaging need may not help it or it’s contents survive the perils of everyday handling.
  • International Plastics and UPS recommend 200 lb. test boxes. They provide more strength and protection than 32 ECT boxes which are a budget-friendly alternative for lightweight shipments
  • International Plastics 200 lb. test boxes are made with heavier paper and have 60% greater bursting strength than 32 ECT boxes.
  • Providing substantial bursting strength means negligible crushed or damaged boxes and content during shipping.
  • International Plastics 100% satisfaction guarantee assures that we stand behind any of our products and that we refuse to sacrifice the quality of our boxes.

How to Measure a Box

  • Listed dimensions are always inside dimensions.
  • Length is always the longest side of the box that has a flap.
  • Width is the shorter side of the box that also has a flap.
  • Depth measurements do no have a flap.
  • NOTE: Acceptable manufacturing variance is approx. +/- 1/8”

Helpful Hints

  • The first dimension is Length.
  • The second dimension is Width
  • Depth is the 3rd dimension and the only side without a flap..
  • To ship via UPS or FedEx®, surround each item with 2” of packing material and place each item 2” away from the walls of the box.
  • To ship via USPS, surround each item with packing materials until items are no longer moving around in the box.
