These 14.5 x 19 inch white poly mailers are built from 2.5 mil polyethylene with a silver interior lining and a white exterior that accepts labels, stamps, and ink without pre-treatment. The self-seal adhesive strip creates a tamper-resistant bond without tape or additional equipment, and reinforced seams hold integrity under full pack loads.

This format is well-matched to apparel, soft goods, documents, and lightweight flat products shipped through e-commerce, retail distribution, and subscription box fulfillment. The internal opening handles folded garments and multi-item soft packs that smaller mailer sizes cannot accommodate.

Sold in cases of 250, the mailers are constructed for high-volume throughput with consistent seal performance across the run. The 2.5 mil gauge provides puncture, tear, and moisture resistance suited to standard parcel handling conditions. Cases ship via parcel carrier.
