Sample Bags

Whirl-Pak® sample bags are a co-extrusion of low-density and linear low-density, virgin polyethylene, giving the bags two important characteristics:


• Exceptionally clear film — easy to see through


• Superior strength — unbreakable sample container


They may be used for taking samples of liquids, semi-solids, or solids. Whirl-Pak® bags are patented under Patent No. 2,973,131 and other patents pending. The film thickness varies from 2.25 mils (0.057 mm) to 4.0 mils (0.102 mm), depending on size and style. Because of the high-quality blended polyethylene, a high mil thickness is not required to achieve optimum strength.
