Which thickness range describes glove bags?

• A. 5 to 7 mil
• B. 6 to 10 mil
• C. 8 to 12 mil
• D. 12 to 16 mil

Answer: (B)

Glove bags need to be thick enough to resist tearing in field use but still flexible enough to seal securely around openings and valves. A thickness of six to ten mil provides that balance: it’s sturdy enough to handle handling and transport without easily puncturing, yet thin enough to be manipulated and sealed without extra stiffness or difficulty.

Thinner ranges (around five to seven mil) can tear more easily, risking leaks that compromise the sample. Thicker ranges (eight to twelve or twelve to sixteen mil) become harder to seal, more rigid, and usually more costly, offering less practical flexibility for typical glove-bag applications. So, six to ten mil is the standard, reliable choice.
