Bag to Nature® compostable bags offer accelerated biodegradation, turning waste into compost for faster introduction back into the environment. Bag to Nature® uses a proprietary blend of biodegradable polymers that BPI (Biodegradable Products Institute) has certified to be biodegradable and compostable in accordance to the ASTM D6400 standard. This special blend of biopolymers maintains its strength, pliability and leak resistance while in use at home, but degrades when introduced into an active compost environment, and doesn't leave behind any harmful residues or toxins. Perfect fit for counter top bins. Doesn't sweat or leak, and won't fall apart! Eliminates the YUCK factor! All our bags are 100% compostable for all curbside, municipal & backyard composing programs as well as everyday needs. Extra Strength! Fast Acting! Eco-Friendly! Sold 20/case, 12 cases.
