A Duffle top is an extension of the bag itself and is folded down to make the top of the bag completely open. This is ideal for companies looking to fill the bag using shovels, loaders etc. To close, the flaps are folded over the top of the bag sealing it completely, and giving a flat surface to the bag. The top is made of a light weight material making it easy to open and fold down.
The flat bottom bag is exactly that, a closed bottom. It is completely shut off with no openings for product to escape at all.
All our manufacturers abide by the ETI code.
