Q1:What is a bulk bag?
A bulk bag is a large bag used for storing and transporting free flowing dry products. Usually made from woven polypropylene, with standard base dimensions of 35"x35" and a variable height generally up to about 96". Bulk Bag dimensions can vary widely, based on user need and usability. Bulk Bags typically hold about 2000-4000 lbs. of product. Bulk Bags can be placed on pallets or lifted by standard lift loops attached to the bags themselves.
Q2:What are bulk bags made from?
100% virgin polypropylene, which is a petroleum based product.
Q3:How do you empty a bulk bag?
Bulk bags are usually emptied by a discharge spout, which is a spout that is attached to the bottom of the bulk bag. Usually the discharge spout is tucked inside a closure on the bottom of the bag. The closure is sometimes called a petal closure, pajama closure, star or x-cut closure. The closure is designed to protect the spout and to prevent the product from sifting out of the discharge before it's intended discharge. Discharge spouts can be customized with specific sizes and closures.
Q4:Can I reuse a bulk bag?
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.
Q5:What does 5:1 SF mean?
A standard bulk bag is rated at a 5:1 Safety Ratio, which means that the bag is specified to hold 5 times the amount of the bags safe working load. A 5:1 Safety Ratio is for single use or single trip bags. Bags that are designed for multi-use or multi-trip bags, are made with an increased SF ratio. The SF for a multi-trip bag is 6:1. Q: Can I patch a bulk bag? Patching a bulk bag is possible, but not recommended, and solely at the users discretion and risk.
