Made from 100% GMO free potato starch and a fully compostable polymer as potato starch has a higher percentage of amylopectin than other starches, these waste bags are the strongest ethical option. Amylopectin gives starch its structural integrity, meaning you can transfer all your food scraps straight to your compost bin without worrying about it holding the waste, whilst also helping significantly towards preserving our planet and natural resources. Blended with compostable polymer and without plasticizers. 30 bags: 43cm x 39cm x 16cm.
