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

- 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.

Frequently Asked Questions
Are 1.5 mil gusseted poly bags food safe?Yes. Our 1.5 mil gusseted poly bags are made from 100% virgin Low Density Polyethylene (LDPE) that meets FDA 21 CFR 177.1520 and USDA specifications for direct food contact, so they can be used for bakery items, produce, bulk dry goods and frozen foods. Can you heat seal 1.5 mil gusseted poly bags?Yes. LDPE heat seals cleanly with an impulse sealer or a constant-heat sealer, which gives a tamper-evident, airtight closure. These bags can also be closed with twist ties, tape, or staples when a heat seal is not required. What is the difference between 1.5 mil and 2 mil gusseted poly bags?1.5 mil (0.0015") is the lighter, more economical gauge and handles most general-purpose packaging; 2 mil (0.002") is roughly 33% thicker and adds puncture resistance for heavier items or products with sharp edges or corners. Both are food safe virgin LDPE. How many bags come on a roll, and what core size do they use?Bags per roll varies by bag size, typically 100 to 1,000 bags per roll — check the individual size listing for the exact count. Every roll is wound on a 3" diameter core with a 1" core plug, which fits most commercial bag dispensers and wall-mount holders. How do you measure a gusseted poly bag?Gusseted bags are measured as Width x Gusset x Length. A 12" x 8" x 20" bag has a 12" face width when flat, an 8" total gusset expansion (4" folded into each side), and a 20" length. Add 2-3" to your product's dimensions to leave room for filling and sealing. Do you offer custom printed gusseted poly bags on rolls?Related Products
