Gusseted poly bags

Custom Gusseted Poly Bags & Liners

Gussets let a bag open into a square base, so it fills a carton or bin with less wasted film and holds more product than a flat bag of the same face width.

Also called side-gusset bags or square-bottom liners.

FAQ

Common questions

How is a gusseted bag measured?

Face width (the flat front), gusset (the fold-in on each side, measured fully open) and length. North American suppliers usually write it W × G × L. Australian and NZ suppliers often write width × width + gusset.

When should I use a gusseted bag instead of a flat bag?

When the bag goes into a square or rectangular container, or when you need a flat base that stands. A flat bag is simpler for round containers or product that is wrapped.
