Do powder free latex gloves contain powder?

Although many suppliers claim they offer powder free gloves. Are they really 100% powder free? No, but its close. There are small traces of powder that may include cornstarch, calcium carbonate aggregates, latex particles, synthetic debris, packaging fibers, non-soluble lubricants, and dust. In most cases powder free gloves have an absolute minimum of powder (defined as anything that does not pass through a 2.7 micrometer glass microfiber filter).
