Are the BRP cake boxes sturdy enough to stack? I'm trying to figure out how to transport cupcakes for a wedding next month. It sounds like BRP boxes are sturdy, but can you stack them? Otherwise how do you fit so many in the car?
I use those boxes meant for Christmas wrap or under bed boxes. The cc's are covered in a liner, so they can sit in a box. Make sure the box does not smell like plastic... it doesn't wash out. Push them close together and make sure there is no room for them to fall. Home Depot has industrial "shelf liner" in black. If your vehicle is flat, you can stack the boxes with the liner on the bottom and in between.
I stack them. Usually for transport I only stack two high, with some non-skid mat in between.
Yes, they are very sturdy boxes.
