Biodegradable bag making machines are considered eco-friendly because of their faster breakdown of the plastic. Biodegradable garbage bags are made of materials that break down into carbon dioxide, water, and biomass. The challenge of biodegradable material is the temperature levels needed to break it down.

Compostable plastic granules are utilized as the raw material and fed into a hopper, where they are melted into a liquid form. The liquid is transformed into a film or sheet using an extrusion machine and then rolled onto a rod.
