1.5 Mil Lay Flat Poly Bags

A 1.5 mil lay flat poly bag is a flat, open-top polyethylene bag with no side or bottom gusset, made from film 1.5 mil (0.0015 inches, about 38 microns) thick. Prism Pak stocks 1.5 mil lay flat bags in a wide range of widths and lengths, made from 100% virgin LDPE resin and sold by the case at wholesale pricing.

Yes. These 1.5 mil bags are made from 100% virgin LDPE resin that meets FDA 21 CFR 177.1520 and USDA specifications for direct food contact, with no recycled content. Common food uses include baked goods, candy, snacks, dry ingredients, and produce.

The difference is film thickness: 1.5 mil film is thinner, more economical, and better suited to lightweight items, while 2 mil film adds puncture and tear resistance for slightly heavier or sharper-edged products. Both are made from the same FDA food-safe virgin LDPE resin, so the choice comes down to the weight and shape of what you are packaging.

1.5 mil bags are built for light-duty loads of roughly 5 lbs or less, depending on bag size and the shape of the contents. For heavier items, sharp edges, or anything that will be handled repeatedly, step up to 2 mil, 3 mil, 4 mil, or 6 mil lay flat poly bags.

The most secure method is heat sealing with an impulse or constant-heat sealer, which creates an airtight, tamper-evident closure and is recommended for food products. Twist ties and paper or plastic bag ties are common alternatives when the bag needs to be reopened; sealers and ties are sold separately.
