The 6 x 9 inch Flat Ship-Lite® Envelope is a white flat-format mailer built from paper reinforced with a poly-mesh fiber screen, giving it substantially greater tear and puncture resistance than standard paper envelopes. The self-seal adhesive strip closes securely without tape or additional equipment, supporting fast, consistent processing in high-volume operations.
These envelopes suit documents, contracts, photos, flat media, and lightweight printed materials that need a more durable enclosure than a standard paper envelope can provide. The clean white exterior makes them appropriate for outbound customer shipments, inter-facility document transfers, and professional correspondence alike.
Construction includes a moisture-resistant barrier that guards contents against humidity and incidental moisture exposure during transit. Sold in cases of 100, with exterior dimensions of 6 x 9 inches, these envelopes are parcel-friendly and stock efficiently in warehouse, fulfillment, and office shipping environments.
