Absolutely, the choice of material will have a significant impact on how your design will appear on your custom packaging. The texture and finish of the material, as well as the printing process used, can greatly affect the final product. For example, if you choose a matte texture or darker material such as kraft boxes, your colors and images may appear darker and more subdued. On the other hand, if you opt for glossy or brighter materials like custom poly mailers, your colors may appear brighter and more impactful. By considering your branding and the desired look you want to achieve, you can leverage different textures and materials to your advantage and create a unique, eye-catching design for your custom packaging.
