These 14 1/2 x 19 inch blue poly mailers are built from 2.5 mil polyethylene with high-strength seams and a self-seal adhesive strip that creates a secure closure without tape or heat equipment. The blue exterior with silver interior lining gives shipments a distinctive, professional appearance that stands out in mixed outbound loads.

These mailers are well suited for e-commerce fulfillment, apparel retail, and subscription box operations shipping soft goods, folded clothing, accessories, and flat flexible items. The outer surface accepts labels, stamps, and standard ink without surface preparation, keeping packing lines moving efficiently.

The 2.5 mil construction resists punctures, tears, moisture, and tampering throughout the shipping cycle. Each case contains 100 mailers and ships via parcel carrier.
