18 x 20" - 4 Mil White Block Reclosable Poly Bags

These 18 x 20 inch reclosable poly bags are built from 4 mil polyethylene with a zipper closure that opens and reseals reliably across repeated use cycles. The integrated white write-on block on the front face accepts handwritten or printed text directly on the bag, eliminating the need for separate adhesive labels.

The write-on block makes these bags especially practical for warehouses, fulfillment centers, and manufacturers tracking high SKU counts — staff can mark item descriptions, quantities, part numbers, or pricing directly on each bag at the point of packing. Retail operations use them for shelf-ready product display where visible identification matters.

At 4 mil thickness, the polyethylene construction resists punctures and holds up under the weight of bulkier contents. These bags meet FDA and USDA requirements for direct food contact, making them suitable for food processing and packaging environments as well. Each case contains 250 bags.
