What thickness range is specified for glove bags?

• A. 4 to 5 mil
• B. 6 to 8 mil
• C. 6 to 10 mil
• D. 12 to 20 mil

Answer: (C)

Glove bags need a thickness that resists tearing and punctures while still being flexible enough to seal around pipes and irregular surfaces. The typical specification of six to ten mils provides a practical balance: about 0.006 to 0.010 inches (roughly 0.15 to 0.25 mm) of polyethylene. That thickness is thick enough to withstand handling and tool contact, yet not so heavy that the bag becomes stiff or hard to seal.

A range like four to five mil is usually too thin for reliable use—these bags can tear more easily during setup or when manipulating material. On the other end, twelve to twenty mil would be much stiffer and more cumbersome to work with, making seals and folds harder to manage and increasing cost. Therefore, six to ten mils is the preferred specification for glove bags.
