What Is a Gusset on a Bag?

If you’ve been shopping for paper or plastic bags, you may have come across the word gusset. But what exactly is a gusset, and why does it matter when choosing the right packaging for your business?

A Simple Definition

A gusset is the expandable section of a bag that adds depth and allows it to hold more items. Gussets are typically found on the sides or bottom of a bag and are most common in shopping bags, grocery bags, takeout bags, and pouches.

In simple terms, a gusset gives a bag structure and capacity, allowing it to expand rather than stay flat.

Types of Gussets

  • Side Gusset – Found on the sides of a bag, allowing it to expand outward. Common in shopping bags and grocery-style paper bags.
  • Bottom Gusset – A fold at the base of the bag that allows the bottom to expand and lie flat when filled.
  • Side and Bottom Gussets – Some bags have both for maximum volume and a box-like shape.

Why Gussets Matter

Adding a gusset transforms a simple flat bag into a functional, load-bearing solution for packaging. Gusseted bags are:

  • Better for bulky or boxy items
  • Easier to pack and stack
  • More comfortable for customers to carry
  • Often more visually appealing when filled
