An eco-mailer is a type of packaging that is designed to be environmentally friendly. It is typically made from sustainable and recyclable materials, such as paper or cardboard, and is designed to minimize waste and reduce the carbon footprint of shipping.

Eco-mailers are commonly used for shipping small to medium-sized items, such as clothing, jewelry, and books. They are often designed to be lightweight and compact, which helps to reduce shipping costs and minimize the use of resources during transportation.

By using eco-mailers, businesses can reduce their environmental impact while still providing a high level of protection for their products during shipping. They are an important part of sustainable shipping practices and can help to promote eco-consciousness in the shipping industry.
