Development of Whirl-Pak® Bags
Developed over 35 ago, American-made Whirl-Pak® bags were the first sterile sample bags on the market. The were designed to provide milk milk hauliers with a container for collecting samples of bulk produced milk. Whirl-Pak® bags made possible the "universal sample system". This means that the single sample can be used for all tests required for quality control, product content and legal complience. Whirl-Pak® sample bags are made from a blended virgin, low-density polyethylene. The blend gives the bags two important characteristics:
They may be used for taking samples of liquids, semi-solids or solids. Whirl-Pak® are patented under US Patent No. 2,973,131 and other patents pending. The film thickness varies from 2.25 mils to 4 mils depending on the size and style. Because of the blended polyethylene, a high mil thickness is not required to achieve optimum strength.
Punture Proof Tabs
All Whirl-Pak® bags feature "Puncture Proof Tabs". This patented process means that the tape on the tab extends past the ends of the wire. The result is no sharp points which could puncture the bags, scratch a person's hands, or puncture gloves. This important feature is found only on Whirl-Pak®, making it easier and safer to use than any other sampling bag. The "Puncture Proof Tabs" process is patented under US Patent No. 5,180,229.
Reduced Storage Space
By whirling or tightly folding the tab over three times, the Whirl-Pak® bag becomes a leakproof container, which:
Importance of Sample Collection
Proper sampling procedures are of vital importance. Laborator findings are completely dependent on the quality of the sample collected. It is imperative that each sample be representative of the lot form whih it came, and that it arrives at the laboratory in the same condition it was in at the collection point. There should be no change in chemical, physical or biological character. All Whirl-Pak® bags are made in the USA.
