Biodegradable Plastic Bags Biodegradable bags are bags that are made from materials that can be broken down by natural processes, such as bacteria or fungi, into their basic components, such as carbon dioxide, water, and biomass. This process is called biodegradation. At Huawei, we're responding to the need for more environmentally sustainable films. Compostable bags are for big brands and small businesses looking to stand out with product packaging that offers a greener solution. Huawei's compostable bags are made from 100% plant-based plastic and are compostable, biodegradable and recyclable. Our compostable bags are made from plant sources such as potato starch or corn. They have the same durability as traditional fossilized plastic bags. Compostable films are translucent white and can be made in a variety of formats and sizes. They are ideal for transporting a variety of products, including food.
