1.5 Mil Gusseted Poly Bags on Roll: Complete Buying Guide
What Are Gusseted Poly Bags?
Gusseted poly bags feature expandable side or bottom folds (gussets) that allow the bag to open and accommodate bulky, awkwardly shaped, or oversized items that won't fit in flat poly bags. When packaged on perforated rolls, these bags become ideal for high-speed packaging lines and busy fulfillment centers.
Why 1.5 Mil Thickness?
1.5 mil (0.0015 inch) thickness provides the perfect balance between durability and cost-efficiency for most applications:
- Lightweight packaging - Reduces shipping costs while protecting contents
- Food safe - Approved for direct food contact (FDA/USDA compliant)
- Clarity - Thin enough for excellent product visibility
- Economy - Lower cost per bag than thicker gauges
Perforated Roll Benefits
Our gusseted bags on roll come with perforations between each bag for effortless dispensing:
- Speed: Tear off bags one at a time without scissors or tools
- Organization: Keeps bags neat and accessible on standard 3" core dispensers
- Efficiency: Reduces packaging time in high-volume operations
- Storage: Compact rolls save warehouse space vs. boxed bags

How to Choose the Right Size
Gusseted bags are measured as Width x Gusset x Length. For example, a 12"x8"x20" bag:
- Width: 12" (face width when flat)
- Gusset: 8" (total expansion depth when opened)
- Length: 20" (height of bag)
Tip: Add 2-3" to your product dimensions for comfortable fit and sealing space.
