Standard open-top LDPE bags. All sizes and gauges.
Lay flat poly bags are the most versatile and widely used packaging solution in the industry. These simple, open-top bags lay completely flat when empty and are made from low-density polyethylene (LDPE) for excellent clarity, flexibility, and moisture resistance. LDPE is the preferred material for general-purpose poly bags because it is chemically inert, lightweight, and easy to heat seal with standard impulse or constant-heat equipment.
Our lay flat bags are available in sizes ranging from 7" x 10" all the way up to 55" x 100", with gauges from 1 mil (lightweight) to 4 mil (heavy-duty). Whether you need small parts bags for hardware kits or oversized bags for industrial equipment, we stock it or can manufacture it to your exact specifications. The 1 mil gauge is ideal for lightweight items like documents, labels, or textile samples. The 1.5 mil gauge handles most general-purpose packaging. Step up to 2 mil for standard industrial parts, and use 3-4 mil when packaging items with sharp edges or significant weight.
Lay flat bags are the most economical poly bag option, making them ideal for high-volume packaging operations. Because the bag is simply a flat tube sealed on one end, there is minimal material waste in production, and the bags stack and store more efficiently than gusseted or specialty styles. This translates directly to lower per-unit cost for your packaging line.
These bags work seamlessly with manual packing, automated filling equipment, and impulse sealers. For manual operations, the open top allows quick loading and sealing. For automated lines, lay flat bags can be fed from wicket frames or dispensed from rolls of pre-perforated bags. The flat profile also makes them compatible with label applicators and printing systems used in fulfillment operations.
All bags are manufactured from virgin LDPE resin at our facility and are available in FDA-grade for food contact applications. FDA-grade lay flat bags use resin that meets 21 CFR 177.1520 requirements, ensuring they are safe for direct contact with food products. This makes them suitable for bakeries, produce packers, candy manufacturers, and any food packaging operation that needs a simple, affordable bag.
