15 x 20 x 4 Mailers

Extra depth gives larger soft goods and bundled orders the space they need without relying on rigid cartons. JAM Paper 15 x 20 x 4 inch poly mailers are well suited to apparel, textiles, linens, promotional products, and other flexible merchandise. The expandable profile adapts to thicker contents while helping keep shipping packages streamlined.

A 4 inch expansion provides useful capacity for garments, fabric products, and grouped customer purchases that exceed the limits of a flat mailing bag. Flexible poly construction offers practical coverage, while the peel & seal closure supports efficient packing in busy fulfillment environments. The white exterior also provides a clear surface for labels and shipping information.

High-volume retail operations often need packaging that stores compactly before use yet accommodates substantial orders when filled. These large poly mailing bags work well for online clothing shipments, warehouse transfers, subscription orders, and bulky non-fragile merchandise. Their dimensional design offers additional packing room without unnecessary box volume.
