Which structure material is the best to create eco-friendly box packaging?

We use many different building materials for the making of Custom Mailer Boxes. Most of them are recyclable and eco-friendly by nature. The best option out of them is the Kraft paperboard. It comes in plain brown color. Different beautification features can be added to their designs to enhance their look and beauty such as die-cut window, embossing or debossing, and others.
