2026-3-17 The customer want to know the difference between these two bag types. How would you explain it?

Using coffee beans as an example, what would you do?

As you can see, the first type is a side gusset bag made from roll and the second type is a pre-made bag with a fat bottom. Both are good options. Our pre-made bags are generally flatter and more good pleasing, which packaging machines cannot achieve. If you require higher production volumes, you can choose to order roll to enable this on your packaging machines.

The biggest difference between these two coffee bags is that one is a roll film bag (with side gusset), which customers fill on an automatic packaging machine, while the other is a pre-made bag (flat bottom), which customers can fill manually or with a bag feeder.

Comparing the two bag types, the side-gusseted bag is more convenient for customers to carry out automatic packaging and filling on the packaging machine. Meanwhile, it has a lower cost compared to the flat bottom bag.
The flat bottom bag is a pre-made pouch, which looks more three-dimensional and rigid, giving it a more premium and high-quality appearance.

From the picture, the first one is the side gusset and the second one is the flat bottom bags. From the standing effect, the flat bottom bags have a flat bottom, and after the side gusset is filled, it can stand. The standing effect of the flat bottom bag is better than the side gusset bag. From the price, the cost of side gusset bag is lower than the flat bottom bag.
