SHELF LIFE AND USEFUL LIFE: Until exposed to microorganisms or similar environments, Eco-Tie will remain stable. When in use, Eco-Tie will remain strong and usable until exposed to microorganisms, excessive heat, or excessive UV exposure. Moisture and heat alone will not degrade Eco-Tie under most conditions. However since moisture and heat allow microorganisms to become more active, these factors can indirectly reduce shelf life and useful life.
