How To Fold Bakery Boxes - Lock Corner Boxes

A guide on how to fold cupcake boxes and other lock corner bakery boxes, plus a quick product review.


In this video, we're going to look at how to fold a 'Lock Corner Box'

What is a lock corner box?

It's a paperboard bakery box that you assemble using interlocking tabs, versus using glued corner or pre-assembled boxes.

They're available in a wide range of colors, shapes, sizes and with or without windows.

How are they different from other boxes?

The advantages of these boxes are that they ship flat for lower shipping costs

The design is simple, so they're easy to manufacture, which means they're a great value for a low cost

They can be stored as flat boxes, or can be pre-folded and nested to save valuable inventory space

They're sturdier and more secure than other types of boxes

The Disadvantages are that they'll require some assembly, and are more time consuming to construct

You'll need to use tape to secure the sides for the best looking box.

So to assemble these boxes, there are 3 main steps

Step 1 - Crease the panels before folding. This will make it easier to assemble. Crease the main panels first, then the side tabs.

Step 2 - Lock the corners. Fold the top up and insert the side tabs into the slots on the side panel. It's easier if you start with the corners closest to the hinge.

Step 3 - Tuck and Tape. Tuck the front tab into the slot on the lid, and use tape to secure the sides

You could also tuck the lid side panels inside of the box, but this exposes the lock-corners which doesn't look as nice, and you could damage your product.

As a quick recap, that's:

  • Crease the Panels
  • Lock the corners
  • Then Tuck and tape
