What Are Gusset Bags?
Gusset bags feature expandable sides that allow them to accommodate bulky or irregularly shaped items. Unlike flat poly bags, gusset bags have pleated sides that unfold to create extra capacity—making them ideal for packaging items that need more room without switching to a larger bag size.

How to Choose the Right Mil Thickness
.6 Mil TUF-R® Gusset Bags
Best for lightweight items under 5 lbs. Ideal for apparel, textiles, and non-sharp objects. Most cost-effective option.
.75 Mil TUF-R® Gusset Bags
Versatile mid-weight option for items up to 10 lbs. Great for food products, industrial parts, and general warehouse use.
.85 Mil TUF-R® Gusset Bags
Heavy-duty protection for items up to 15 lbs or sharp/abrasive contents. Maximum puncture resistance.
What Makes Linear Low Density Polyethylene (LLDPE) Superior?
Traditional low density polyethylene (LDPE) bags can tear easily under stress. TUF-R® bags use LLDPE—a superior polymer that offers:
- Higher tensile strength - Resists stretching and breaking
- Better impact resistance - Withstands drops and rough handling
- Improved puncture resistance - Protects sharp or angular items
- Enhanced clarity - See contents clearly for inventory management
- Low temperature flexibility - Won't crack in cold storage
Frequently Asked Questions
What is a gusseted poly bag?A gusseted poly bag is a plastic bag with pleated, expandable sides that unfold to add depth, so it holds bulky or irregularly shaped items that would not fit a flat bag of the same width. A gusset bag listed as 8" x 4" x 20" is 8 inches wide, expands 4 inches deep at the sides, and is 20 inches long. TUF-R® gusset bags are made of linear low density polyethylene (LLDPE) and are used for bakery goods, produce, hardware, apparel, and bin liners. Are TUF-R® gusset bags food safe?Yes. TUF-R® gusset bags are manufactured from FDA-compliant resins suitable for direct food contact and meet FDA 21 CFR 177.1520. That makes them appropriate for bakery items, produce, bulk dry foods, and frozen goods in commercial kitchens and food processing. What mil thickness gusset bag do I need?Match the mil to the weight and shape of the contents: .6 mil for lightweight items under about 5 lbs such as apparel and textiles, .75 mil for items up to about 10 lbs such as food products and general warehouse use, and .85 mil for loads up to about 15 lbs or for sharp and abrasive contents. Thicker film costs more per bag but reduces tearing and product loss, so heavy or angular items are usually cheaper to run at .85 mil. What is the difference between LLDPE and LDPE bags?LLDPE (linear low density polyethylene) has higher tensile and puncture resistance than standard LDPE, so an LLDPE bag can be run at a thinner gauge for the same strength. LLDPE also stays flexible in cold storage and resists cracking, while LDPE tends to be softer and tears more readily under stress. TUF-R® gusset bags use LLDPE for that strength-to-thickness advantage. Can gusset bags be heat sealed?Yes. TUF-R® LLDPE gusset bags seal cleanly on impulse sealers, continuous band sealers, and vacuum sealers. Seal across the flat portion above the gusset for the most consistent seal, since the folded side pleats add extra layers of film at the gusset itself. Can I get custom printed gusset bags?Yes. Prism Pak prints gusset bags with logos, product information, and barcodes, and can produce custom sizes outside the stock range.
