Flexible Packaging / Side Gusset Bags
Custom side gusset bags shaped around your product and fill direction.
A side gusset bag uses expanding side panels to create more pack volume when filled. A strong project brief explains what will go inside, how the package is expected to stand or be displayed, and which packaging details are important.
Start with the brief
Use the expanding side profile to guide the first packaging discussion.
The name of the format is only the starting point. A useful side gusset bag conversation considers product type, fill level, pack silhouette, surface area for information and the customer experience around opening or repeat use.
Product & capacity
Describe the product, the amount to be packed and the package shape you are considering once it is filled.
Side panel role
Explain whether the expandable side area, print layout or upright presence is important to the brand or retail plan.
Project details
Share artwork status, reference samples, market, quantity and any feature questions that should shape the next discussion.
Where it can fit
The side gusset format can be explored for product categories that need a taller, filling-driven pouch silhouette.
The format is often considered for coffee, dry goods, snacks and other products where the product fill and pack profile influence the packaging direction. Each project still needs its own discussion of product, fill and desired presentation.
Coffee packaging
Start with the coffee product, fill direction, desired shelf profile and the packaging details you want to discuss.
Dry goods
Use product type, fill, handling and retail presentation as the first inputs for a gusseted bag conversation.
Snack & specialty products
Bring the product, use pattern and visual direction so the pack silhouette can be assessed in context.

What is a side gusset bag?
It is a flexible bag format with side panels that expand as the bag is filled, creating a taller package profile and added internal volume.
How does a side gusset bag differ from a flat bottom pouch?

What should I include in a side gusset bag inquiry?
Include the product, approximate fill, target package direction, retail or use context, artwork status, quantity and any features you want to discuss.
Can I ask about closure or valve options for a side gusset bag?
Yes. Mention the product use and the opening or package experience you are trying to achieve. The project discussion can identify which details need to be reviewed.
