4 x 4" - 2 Mil Flat Poly Bags

These 4 x 4 inch flat poly bags are constructed from 100% virgin polyethylene film at a 2 mil thickness, delivering reliable protection against dirt, dust, and moisture. The open-end design accepts twist ties, bag tape, or impulse sealers, giving operations flexibility in how each bag is closed and sealed.

The FDA and USDA compliant construction makes these bags appropriate for food-contact and regulated applications. Common uses include small parts packaging, hardware containment, retail bagging, sample presentation, document protection, and food-adjacent product packaging in manufacturing, fulfillment, and distribution environments.

The square format is a high-demand size well matched to small components, fasteners, and similarly compact products. Each case contains 1,000 bags, and the parcel-friendly format supports routine replenishment for facilities managing ongoing packaging inventory.
