Gusset Bag

In flexible pouch packaging, the gusset is a piece of material used to add extra space to packaging. This is a panel that can be folded into a flat surface, but will unfold when loaded with items.

Side gusset bags

The gusset pouch packing machine can add gussets to both vertical sides of the pouch, resulting in a lying fat pouch. The side gusset pouch provides much more space and increased flexibility for your products. Usually, side gusset pouches have only one seal on the side. 

Bottom gusset bags

When combined with a flat bottom or bottom gussets, gusset pouches can stand upright, bringing a sturdy and flexible packaging option. When holding the same volume of products e, bottom gusset bags appear to be larger.

Overall, side gusset bags are very convenient for case packing and pallet stacking.

Basically, gusseted bags look similar to pillow bags but feature side gussets. In other words, gusset bags can be made without much difficulty. Only gusset devices need to be added to the pillow packaging machine.

Gusset devices are located on both sides of the forming cylinder of the pillow packaging machine, which correspond to the heat sealing devices.

During production, when the packaging film passes through the bag forming device, the bag former makes the film into a cylindrical structure.

After being filled with the products, the cylindrical shape film would be transported to the heat sealing device through the film feeding wheel. And then, the two gusset devices would press on both sides of the rolled film and create two gusset angles, which were sealed and cut immediately afterwards.

As you consider gusset bags as your packaging solution, trial run packaging is imperative.

Below are tests that can be done to evaluate the quality of the gusset bag and the performance of the automated pouch packaging machine. Carrying out these tests can reduce the risk of gusset bag packaging problems, such as leakage and rupture, as much as possible.

Puncture Test: The gusset pouch must be able to resist external factors that could damage it or puncture it.
Leakage Test: Test the gusset pouch sealing for strength to ensure it can withstand the volume of your product.
Insulation test: This test is used to determine whether the pouch is strong enough to protect your product from external factors such as heat, dust, and oxygen.

Gusset bags offer several advantages in retail, including increased product visibility, efficient storage, and branding opportunities. They can also accommodate various product sizes and shapes, providing flexibility.
