Yes, however, bulk bags will degrade as a result of UV exposure. A standard bulk bag has a UV inhibitor added into the fabric at the manufacturing level. Manufacturers add enough UV inhibitor to resist UV rays for approximately 1600 hours. Although this is dependent upon where the actual bag is located and what type of weather conditions, sometimes extreme, can happen in this region. UV rays vary in strength and degree in different parts of the world. Therefore, storing bulk bags outside is not recommended, but we do realize that it happens.
