These 7 1/2 x 10 1/2 inch poly mailers are built from 2.5 mil polyethylene, delivering puncture, tear, and moisture resistance in a lightweight envelope format. A self-seal pressure-sensitive adhesive closure secures contents without tape, while a recipient-facing tear strip enables clean, easy opening without scissors or damage to enclosed items.

Suited to e-commerce fulfillment, retail distribution, subscription box operations, and direct-to-consumer apparel shipments. The white exterior accepts printed labels, stamps, and standard shipping ink clearly, while the silver interior lining adds a secondary layer of protection for items sensitive to light or handling abrasion. High-strength seams hold under load without splitting at the edges.

Each mailer is sold in packs of 100. The format accommodates documents, soft goods, folded apparel, and flat flexible items. Cases ship via parcel carrier, supporting routine replenishment for facilities moving consistent volume.
