These 9 x 12 inch reclosable poly bags are built from 3 mil polyethylene with a single-track zipper spanning the full bag width. The heavier gauge delivers meaningful puncture and tear resistance compared to standard 2 mil alternatives, making the closure reliable through repeated open-and-close cycles without seal degradation.

The FDA and USDA compliance rating opens these bags to food-contact and regulated-product use alongside general applications — components storage in electronics assembly, retail bagging of apparel accessories, pharmaceutical sample containment, and document or parts kitting in distribution environments.

Dimensions listed are interior usable measurements, supporting accurate fit planning before ordering. Each case contains 1,000 bags at an approximate case weight of 33 lbs.
