Corrugated Cardboard Shipping Box Size & Strength


Let’s talk a moment about box strength. We know what types of corrugated boxes there are, and we realize the importance of custom print on a box, but now – in a real-world, practical, logistical sense – box strength matters as well. Whether your box shows up in the same good-looking condition you sent it or in tatters with the bottom falling out will make a huge difference in the views of your customers. The box they hold in their hands (not the box you hold in your hands) tells the customer a thousand stories about your company.

The strength of your shipping box will vary depending on its size and the strength of the corrugated used in its construction. The bigger the box, the stronger the wall strength it can hold. This is convenient, since a bigger box will necessarily need to be stronger because it is designed to carry more matter inside.

Options from Custom Boxes Now! range as follows:

  • “STANDARD” strength box: Single-wall, 32 ECT; we do not recommend exceeding 65 lbs and 75 total inches of measurement.
  • “STRONG” box: Single-wall, 44 ECT; we do not recommend exceeding 95 lbs and 95 total inches of measurement.
  • “EXTRA STRONG” box: Double-wall, 51 ECT; we do not recommend exceeding 105 total inches and 120 lbs.

We offer many more strength options, including burst strength measurements (ie: 200 lbs per square inch). Contact us if you need to discuss box strength options beyond those available on our online box configurator. The box must be strong enough to carry its cargo to its destination and survive the trip intact.

Advantages of Corrugated Cardboard


What is Corrugated Cardboard?

Corrugated cardboard is cardboard that has been reinforced with more cardboard. Specifically, there are two parts to a corrugated cardboard box: linerboard and medium. The linerboard is the flat paper on the side; the medium is a more three-dimensional layer of wavy paper. Sometimes, as on single-face corrugated cardboard, there is only one side of linerboard, with the medium exposed. In single-wall (or double-wall, or more) corrugated cardboard, the medium is hidden in between two layers of linerboard, creating flat surfaces on both sides.

Corrugated Board

The image above shows the linerboard and medium of a single-wall sheet of corrugated, the most common combination used for shipping boxes.

Why Is This Great?

1. Protection
The wavy, fluted three-dimensionality of the medium provides a compact and lightweight layer of protection. Single-layer chip board (like the kind used for cereal boxes) isn’t usually used for shipping because it’s barely any protection at all, and shipping can be hazardous. A corrugated cardboard packing box provides much stronger protection against the elements (and against the wear and tear of travel and shipping) with the cushioned paper padding inside. It’s also better than plastic or wood because it’s lighter, far less expensive, and easier to recycle. Corrugated cardboard is therefore better for the environment and better for the pocketbook.

2) Printing
The flat linerboard, also being made of paper cardboard, is also an easier and less expensive surface onto which to print custom graphics. Custom print jobs are common on cardboard boxes for products that are shipped, stocked, stacked, sold, reused, repurposed, and recycled all over the world. (We’ve mentioned the importance of custom print for customers before.) The dual functionality of wavy inner layer for protection and flat outer layer for structure and printing make corrugated cardboard shipping boxes the ideal bridge between marketing and logistics for getting your product into the hands of your customers.
