Compostable film products include things like liners for compost bins, shopping bags, food service gloves, cling wrap and produce bags. These are products that can be used to transport compost in community and commercial compost programs.
They're made of compostable resins. They are typically composed of compostable biopolymers, PBAT and PLA. This allows them to decompose as easily as a banana peel.
It's important not to confuse the term "compostable" with terms like "biodegradable", "oxo-degradable", or "photo-degradable". Products that use these terms often include polyethylene. While they may break down into smaller pieces of plastic, they don't decompose completely like a "certified compostable" product would.
