We have customers who choose to reuse the pouches and with the reinforced design and durable material, they have done so successfully. Others prefer to use and recycle. The number of times a pouch can be used depends entirely on handling, as well as content, and temperature, and therefore cannot be guaranteed. If you choose to re-use, simply wash with warm soapy water, rinse and air dry. To dry, place a few drinking straws in a glass and slide a single pouch over each straw. Baby bottle drying racks work great for air drying as well. For safety, be sure to check each pouch to ensure it is intact, without holes or bite marks, especially when children are involved.
