What Is a Box Dieline? Why Printed Paper Becomes a Structure

A box dieline is a drawing that unfolds a three-dimensional object into a flat plan. In box production, it shows how a box is constructed on flat paper before assembly through crease lines and cut lines.

What do crease lines and cut lines mean in package design?

Crease lines in box dielines

A post-processing step that uses a machine to press fold lines into paper so packaging can be folded neatly and easily.

Cut lines in box dielines

Introducing the box dielines used at Packative

The Packative packaging design editor currently offers three box types.

Product box dieline

Product boxes use a three-side glued structure, with all four side panels connected, making it relatively easy to create a design that flows without interruption. However, the top structure where the box opens may not line up once the actual box is assembled, so it is best to place the design in the center. We also recommend simplifying the design on the bottom where the three-side glue is applied.

Pillow box dieline

A pillow box has very few corners, making it a very convenient structure for design. However, be sure to check whether to include the design on the upward-folding lid before finalizing it.

Also, designing mainly around the areas with crease lines rather than the glued sections is more suitable for creating a continuous, seamless design.

Mailer box dieline

Mailer boxes are designed to be sturdy, so they tend to have more crease lines and extra flaps than other box types.

As a result, they have more inward-folding sections and surplus space, and because the design can flip depending on how the box is folded, you need to carefully consider what the dieline will look like once folded when developing the design.

Box dieline mock-up

The 3D preview shows how the box dieline folds into its final form!

By folding the dieline in the 3D preview just as it would fold in real life, you can visualize how the box will actually print, making it easier to design according to the dieline.

If you don't know how to create a mock-up, try adding your design to the dieline through the Packative editor and check the 3D preview instantly!

If the dieline you want isn't on the list, feel free to contact Packative anytime!
