PP jumbo bag/woven big bag frequently asked questions

Q: What is a Jumbo bag?A Jumbo 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". Jumbo Bag dimensions can vary widely, based on user need and usability. Jumbo Bags typically hold about 2000-4000 lbs. of product.

Q: What are Jumbo bags made from?100% virgin polypropylene, which is a petroleum based product.

Q: What is woven polypropylene made from?Woven polypropylene is made from extruded polypropylene resin, which is made from petroleum feedstocks.

Q: What sizes do jumbo bags come in? Jumbo Bags come in many different sizes, they can be customized into just about any 3 dimension size possible. There are limits to the sizes of course, but usually you'll see standard jumbo bags with a standard base dimension of 35" x 35". The heights of a jumbo bag can range up to 96 plus inches tall. Again, the size and dimensions of jumbo bags are determined by safety, functionality and usability by the customer.

Q: Are Jumbo bags water-tight or water proof?No, since a jumbo bag's fabric is made from a woven material, the bag is not "water proof". Users usually want a coating or lamination as a moisture barrier, by moisture barrier we mean a light amount of condensation or light amount of water. Lamination is simply a moisture barrier, however the use of an internal poly liner works best in many typical applications, technically it still is not 100% water proof. The difference between using a coating/lamination or using a liner is in the amount of moisture that you are trying to keep out of the product, and how much you want to assure that this does not occur. Standard jumbo bags are not water proof, and are not typically designed to carry wet products, however there are other type products in the market designed to hold liquid, i.e. liquid liners.

Q: How do you pick up a jumbo bag? Jumbo bags are lifted by 1 of several types of lifting application. Some examples are standard 10" lift loops, lifting sleeves, single point crane lift, and stevedore straps. There are other designs that are made to lift bulk bags as well. Lifting options can vary and are all custom-tailored, i.e. 15" lift loops.

Q: How do you empty a jumbo bag? Jumbo 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.
