Side Gusset Bag

Home \ Capabilities \ Pouching \ Side Gusset Bag

Side gusset bags offer additional space for product volume and graphics.

Fin Seal/Lap Seal/Quad Seal

These types of side gusset bags are produced from a single web. Joining the edges of the web creates a seam that will become a “fin” on the back or offset to the side. If preferred, the fin can also be tacked down to create a “lap seal”. The seam can even be completely disguised by rotating the fin to an edge and sealing all four edges (quad seal bag).

While these styles of bags do not have flat bottom gussets, the bottom of the bag can be folded and glued to create opportunities for added stability or brand identification when the bags are stacked on store shelves (common for large, high volume and heavy bags such as pet food).

Pinch Bottom

In contrast to fin seal, lap seal, and quad seal bags, which are formed from a single web, the pinch bottom utilizes a separate web to insert the side gussets. This is ideal for side gusset graphics that bleed all the way to the edges or for different colored/clear side gussets. All four edges are sealed and the bottom corners are tacked together. Rounded corners are standard on pinch bottom products. The folded and glued bottom is also an option for added stability on the shelf.

Available Side Gusset Bag/Pouch Features

Tear Notches

Tear notches provide a starting point for the consumer to tear the product open.

Hang Holes

A hole punched into the top of the product allows it to hang on a hook in the store.

Handle Holes

Standard or custom handle holes assist the consumer with carrying large, awkward or heavy products.

Zippers & Closures

Our variety of zippers includes small and large flange, leak-resistant, hook-and-loop, tactile, soft touch, and powder-resistant.


Vents allow air to move through the product and prevent it from bursting when squeezed or flattened.


A dashed line is punched through all film layers to assist the consumer in opening the pouch (typically placed between tear notches).

One-Way and
Two-Way Valves

One-way valves allow gases to escape the pouch without letting oxygen in. Two-way valves function as a vent.



Labels, such as removable coupons or freshness seals, can be applied during the production process.


Inkjet Printing

Codes can be printed on the pouch during production for traceability, reward codes, or any other application.


Folded & Glued Bottom

The bottom of the product can be folded and glued to create an extra panel. This can provide stability for smaller packages to stand upright. For larger, high volume, and heavy bags (such as pet food), a folded and glued bottom keeps brand identification visible when the bags are stacked on shelves and the bottom faces the consumer.
