I’ve been working for “Big Cardboard” for a number of years and there’s a few points I’d like to bring forward.
For one thing, we have plenty of custom designs for self-assembling boxes - this is in no way a new or innovative idea in and of itself. The design that’s shown on the video is a nice one, nothing wrong with that, but it’s a variation on an idea that’s been used already, and if you visit some specialized sites that sell cardboard, you’ll see possibly less clever designs but with similar function that work. The reversible idea is a nice touch, too.
However, the claim that their design uses 15% less cardboard than the equivalent from a regular slotted carton is completely false. At the same interior size between the 2, the design of their box will use more cardboard. You have to think that this design is for a die-cut box, and the sheet from which the box will be cut will have to be a bit larger than the flat design. A regular slotted carton will use (Height+Width) X (LengthX2)+(WidthX2)+GlueLap. So if I have a 6X6X6 box with a 1 inch glue lap (tbh, we mostly like 1 1/2" glue laps), I will end with a sheet that’s 12 X 25, which will use 2.08 square feet of cardboard. Their design, without trim, will use (HeightX2)+(LengthX2)+extra for lock portion, say 2 inches on the large bottom and 1 inch on the top ears, all of this X (Width+HeightX2)+extra for side laps, say 2 inches on each side. So again, with a 6X6X6 carton, we end up with a sheet that’s 27 X 24, which amounts to 4.5 square feet of board. More than double the carton than the regular slotted container. In this industry, board is what we sell, and more of it means we charge more.
Another thing that will hurt this idea will be the steel die cost. Typically, for such a design, a steel die would probably cost around 800$CAD. Any variation on size means a new steel die, and the cost of those will grow as the size does. Larger customers won’t mind this, but smaller users are rarely interested in investing on tooling, even if there are many advantages to those.
Finally, the custom jig is another thing that will make this a hard sell to any given customer. Those will be expensive and hard to develop, until 3D printing technology makes its way in the larger world, when it will likely cease to be a problem.
