These 12 x 18 inch reclosable poly bags are built from 4 mil polyethylene, producing a puncture-resistant barrier that outperforms standard 2 mil alternatives for heavier or irregularly shaped contents. A large white write-on block is printed directly on each bag, eliminating the need for separate adhesive labels and keeping identification fast and consistent at the pack station.

The zip-style reclosable seal supports repeated opening and closing without losing integrity, making these bags practical for retail display, parts storage, sample kitting, and food-adjacent packaging. FDA and USDA compliance for direct food contact broadens their use into grocery, deli, and specialty food distribution alongside general industrial and fulfillment applications.

Dimensions reflect interior usable measurements: 12" wide by 18" long. The 4 mil gauge is specified at manufacture; the reclosable zipper closure is functional but not rated for airtight containment. Each case contains 500 bags.
