Paper packaging is usually associated with boxes. However, this versatile material is great to create curved structures.
Here are some samples of curved paper packaging designs. Some of them are made with folds, while others are made with round surfaces.
To create curved shapes you need a good knowledge of paper design. Here are some interesting tips to help you create curved paper packaging designs.
Here is a template with straight and curved lines. To made the round creases all you have to do is change the folding lines. Try this with other basic packaging templates.
Another technique is to extend the lid and make it curve over the box. In this case, instead of changing the folding line we simply remove it. This forces the paper to continue, forming a round surface.
To help you study, here is a curved packaging design from Smuzi. Just download the PDF, print and assemble it.
