Yes, bulk bags can be reused. This requires a multi-trip bulk bag, which is made with a 6:1 Safety Factor. This type of bag is designed to be used for a specific amount of uses. Some users reuse bulk bags with a 5:1 SF, in fact it is a common occurrence. We do not recommend this practice, as reusability must also take into consideration the reality that the bag may be worn, or have a small hole in the fabric, the loops could be unstable etc. Reuse of a 5:1 SF bulk bag, which covers the majority of bulk bags seen in the market, is not recommended.
