These 4 x 12 inch flat poly bags are manufactured from 100% virgin polyethylene film at a 3 mil thickness, delivering a puncture-resistant, moisture-blocking barrier that outperforms standard 1 and 2 mil alternatives. The open-top design accepts multiple closure methods — twist ties, bag tape, or impulse heat sealing — giving operations flexibility to match existing packing workflows.

FDA and USDA compliance makes these bags a reliable option for food processors, bakeries, and regulated production environments. Beyond food applications, the 3 mil construction handles parts, hardware, textiles, and small components in warehouse, distribution, and light manufacturing settings where extra film strength reduces bag failure at the line.

Each case contains 1,000 bags. This format suits elongated or narrow items such as pens, brushes, cutlery, tubing, and individual hardware pieces.
