In the packaging industry, the term dieline refers to a template that ensures the accurate layout of your packaging. It serves as a diagram of your packaging that marks all the folds and cut lines.
Graphic designers create the dieline templates used in packaging production, such as envelopes, boxes, mylars, and more.

How to Customize a Dieline?
Customizing a dieline is an excellent way to create distinctive packaging for your product. You can use graphic software programs like Adobe Illustrator to make this process straightforward. With its user-friendly tools and templates, Adobe Illustrator can simplify the design process.

To maintain straight edges and guidelines, you can follow the steps below:
- Create a new layer by clicking on the layer option.
- A dialogue box will appear that allows you to specify the desired width for your guidelines (e.g., “1mm”). You need to press Enter.
- The next steps closely resemble those you’d follow in CorelDRAW or similar software.
Moreover, when designing a dieline template, there are some requirements you must consider:
- A dieline must be developed as vector art on computers, as computers require mathematically described lines.
- Focus on the packaging specifications you have while building a dieline.
- Consider creating a hard copy prototype of the dieline to catch errors before the final production.
