Write-On Whirl-Pak bags make sample identification easy. Designed with a white write-on strip that can be written on with an ordinary ballpoint pen, pencil, or felt-tip marker with no smearing. Ideal for milk, water, and food sampling. To assist in volume control, the top of the white strip can also be used as a fill line (all fill lines are approximate).

Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate. Bags should not be used at temperatures above 180°F (82°C). Bags can be frozen to any temperature, even liquid nitrogen; careful handling is required after freezing. All bags are EO gas-sterilized after manufacturing.
