These 7 1/4 x 12 inch self-seal nylon reinforced mailers combine tear-resistant construction with a peel-and-seal closure, offering a lightweight alternative to padded bubble mailers for flat and semi-rigid shipments. The self-adhesive strip uses natural rubber adhesive that bonds without moisture activation, creating a tamper-evident seal.

Well suited for e-commerce fulfillment, professional services, and retail distribution, these mailers accommodate standard letter-size documents, contracts, catalogs, photographs, and flat product inserts. The reduced unit weight compared to cushioned mailers helps manage per-piece carrier weight charges on high-volume outbound shipments.

Nylon fiber reinforcement runs throughout the envelope body, resisting tearing and puncture during transit. The #1 size designation is an industry-standard format reference. Each case contains 1,000 mailers and ships via parcel carrier.
