These 6 x 9 inch poly mailers feature a transparent front panel paired with an opaque back panel, giving senders a clear view of enclosed contents while keeping the address and postage area clean and legible. The 2.5 mil poly construction provides reliable tear resistance through standard transit and handling conditions.

The clear front panel supports visual content verification without opening — a practical advantage for e-commerce fulfillment centers, retail distribution hubs, direct mail operations, and apparel shippers processing high daily volumes. The double perforation tear strip along the top edge lets recipients open mailers cleanly without scissors or a blade.

Each mailer closes with a pressure-activated self-seal adhesive strip that requires no moisture activation. Cartons contain 1,000 mailers and ship via parcel carrier, supporting efficient bulk replenishment for ongoing fulfillment programs.
