Side Gusset
Poly bags with expandable side panels that open out to add capacity — built to contour to a box shape.
What are side gusset bags?
Side gusset bags have expandable side panels that open out when the bag is filled, creating extra capacity. They are measured by width × depth × length and built to contour to a box shape.
They are often used as box liners or trash liners for applications that need structured storage or disposal.
