Whirl-Pak® bags made possible the "universal sample system", which means that a single sample can be used for all tests required for quality control, product content, and legal compliance.


  • A convenient white Write-On Strip will accept virtually any writing instruments (ballpoint pen, pencil, or felt-tip marker) for easy sample identification
  • High-quality blended polyethylene bag for maximum strength
  • Puncture proof tabs by extending the tape on the tab past the aluminum wire ends eliminating the sharp points which could puncture the bags or gloves
  • Leakproof closure (whirling or tightly folding the tab over 3 times) prevents impurities from entering the bag and contaminating the sample
  • Sterile with +1 Sterilization, a process of sterilizing sealed cartons of Whirl-Pak® bags after manufacturing using ethylene oxide gas at an independent ISO-certified facility
  • Not autoclavable
  • Bags should not be used at temperatures above 180°F (82°C)
  • Bags can be frozen to any temperature, even liquid nitrogen temperatures down to -346°F (-210°C); careful handling required after freezing
  • ISO9001 certified
  • FDA approved for food contact
  • Capacity: 7oz (207ml) - Capacity is measured in fluid ounces when the bag is closed and tab is folded over 3 times
  • Size: 3 3/4" W x 7" L (9.5cm x 18cm)
  • Thickness: 2.5 mil (.064mm)
  • Patent No. 2,973,131
