Need reliable sample bags for lab, field, or food use? These Whirl-Pak Sampling Bags are a classic choice. They measure 3.75 x 7 inches, are 3 mil thick, and hold up to 7 ounces of solids or liquids. Each bag has a unique double wire and tape frame at the top that keeps it open while you fill it. To seal, you just whirl the top over the wires three times and fold the tabs down – it creates a tight, moisture-proof, and air-tight seal that's perfect for preserving samples. Handy pull tabs make them easy to open. The material is low-density polyethylene that meets USDA and FDA standards for food and agricultural sampling. Disposable, sterile, and super handy for environmental testing, food safety, research, or any situation where you need clean, secure sample containers.
