Stone paper bags are a type of eco-friendly packaging made from a material called stone paper. Unlike traditional paper bags made from wood pulp, stone paper bags are made from calcium carbonate, a mineral found in rocks. The production process involves crushing the calcium carbonate into a fine powder and mixing it with a small amount of high-density polyethylene (HDPE) resin to create a durable, tear-resistant material that can be made into bags.
Stone paper bags are an environmentally friendly alternative to traditional paper bags, as they do not require trees to be cut down for production. Additionally, they are waterproof, reusable, and recyclable, making them a more sustainable choice for packaging.
Stone paper bags have a smooth texture and are available in a range of colors and sizes. They can be customized with branding or artwork, making them a popular choice for businesses looking for eco-friendly packaging solutions
