1 roll of 18 bags 🌎BIODEGRADABLE GARBAGE BAGS: Unrecycled plastic creates nearly 730,000 tons of non-biodegradable garbage every year and take centuries to break down. Eco Green Living Biodegradable Bin Liners are made from Corn Starch so it will turn to compost in months, not lifetimes. 🌎EXTRA HEAVY DUTY: Our garbage liners match other top brands for holding heavy trash, but without any of the ecological waste! Strengthened & lightweight, our durable garbage bags are 25 microns thick and are completely compost friendly. They measure 104cm around and 64cm long to fit 20L and 30L bins- especially the tall slim kitchen bin! 🌎NATURAL SOURCING: Corn starch is actually a polymer but we only see it in powdered form. When you apply just the right amount of heat and water, the particles bond to themselves and you have all natural plastic! Our bin liners are certified compostable ASTM D6400 standard and contains no micro plastics.
