Paper like coating actually eliminates ink stains and provides a surface that can accept various writing tools. When the bag is closed and the label is folded, the capacity is measured in fluid ounces. The volume and size are approximate values, and this sampling bag cannot be used at temperatures above 180 ° F (82 ° C). It can be frozen to any temperature, even in liquid nitrogen environment, and careful handling is required after freezing. All bags are disinfected after manufacturing.
