These 19 x 24 inch poly mailers are built from 2.5 mil polyethylene with a white exterior and silver interior lining. A self-seal adhesive strip closes the mailer securely without tape or equipment, while an integrated tear strip lets recipients open the package cleanly without scissors or a knife.

The 2.5 mil construction resists puncture, moisture, and tearing, and high-strength seams hold under load when contents fit tightly. The outer surface accepts shipping labels, stamps, and direct ink printing without adhesion failure, supporting standard warehouse labeling and postage workflows.

These mailers are well suited for e-commerce fulfillment, retail distribution, and manufacturers shipping apparel, soft goods, documents, or other lightweight non-fragile items. Sold in cases of 250, the bulk format reduces per-unit cost for high-volume shipping operations.
