How to Measure Gusseted BagsGusseted bags are measured as: Width x Gusset x Length. For example, a 6" x 3" x 15" bag has a 6" face width, 3" expandable side gussets (1.5" each side), and 15" length. When expanded, the bag can hold items up to 6" wide x 3" deep. Ordering & Volume DiscountsAll gusseted poly bags on roll are sold by the roll. Quantity discounts automatically apply at checkout.

Frequently Asked QuestionsWhat is a 4 mil gusseted poly bag on a roll?A 4 mil gusseted poly bag on a roll is a clear low density polyethylene bag 0.004" thick with expandable side gussets, wound on a 3" core with perforations between each bag. The gussets let the bag lie flat for storage but open wide to hold bulky items such as bread loaves, produce, or hardware, and the perforations let you pull and tear off one bag at a time without scissors. Are 4 mil gusseted poly bags food safe?Yes. These bags are made from 100% virgin LDPE that meets FDA 21 CFR 177.1520 and USDA specifications for direct food contact, so they can be used for bread, pastries, cookies, produce, bulk candy, and coffee beans in bakeries, delis, and farmers markets. How do you measure a gusseted poly bag?Gusseted bags are measured as width x gusset x length. A 6" x 3" x 15" bag has a 6" face width, 3" of total side gusset (1.5" folded into each side), and a 15" length, so when expanded it holds an item up to about 6" wide and 3" deep. Add 2 to 3 inches to the length of your product to leave room for closure. What is the difference between 2 mil and 4 mil gusseted bags?4 mil bags are twice as thick as 2 mil bags, so they offer noticeably better puncture and tear resistance for heavier items or products with sharp edges, while 2 mil costs less per bag and suits lightweight goods. Choose 4 mil for hardware, auto parts, frozen items, and dense food products. Can 4 mil gusseted poly bags be used for frozen food?Yes. LDPE stays flexible at freezer temperatures and performs across roughly -60°F to 180°F, and the 4 mil gauge resists the cracking and splitting that thinner bags can show after long frozen storage. How do you close a gusseted poly bag from a roll?Heat seal the bag with an impulse sealer for a tamper-evident closure, or tie, staple, or tape it shut. LDPE heat seals cleanly at 4 mil, and the roll format lets you dispense, fill, and seal in one motion at a packing station. Are 4 mil gusseted poly bags recyclable?Yes. LDPE is a #4 plastic and is recyclable at facilities that accept #4 plastic film, including many store drop-off programs. Check your local guidelines, since curbside acceptance of plastic film varies by municipality. Do you offer custom printed gusseted poly bags?Yes. Custom printed and custom sized gusseted poly bags on rolls are available, including anti-static options.
