In our continuing effort to provide you with the highest quality, most cost effective hobby supplies, we made some improvements to the BCW Short Comic Box and Long Comic Box. We have improved the design so they fold together easier and the corners are clean and square. This was accomplished by changing the corrugated double-wall construction from a combination of B and C flutes to a combination of B and E flutes. Additional benefits of the new designs are that bundles of the new boxes occupy less space, and the E flute on the outer wall provides for a much smoother surface.

Prior to implementing the design change, we ran two separate tests using samples of the BCW Short Comic Box in both configurations. Below are the results of those tests.

The ECT, or Edge Crush Test, is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated paperboard. It gives information on the ability of a particular board construction to resist crushing and is expressed in kilonewtons per meter (kN/m).

The Mullen test is used to measure the bursting strength of corrugated paperboard and is usually expressed in pounds per square inch (psi). Mullen tests are performed for each side of the paperboard, and the bursting strength is expressed as the average of both sides.

As you can see from the test results above, there is very little difference between the flute combinations in terms of edge crush or burst strength which is why we decided to take advantage of the benefits of the new design.

We are also adding UPC codes to each of our boxes, including the Short Comic Box and Long Comic Box, to support our customers who have point-of-sale systems, and for those who have integrated systems for warehouse, shipping, and receiving applications. Easy to follow instructions for the assembly of the Short Comic Box and Long Comic Box are now printed on the bottom panel and are hidden from view once the boxes are constructed.
