These 4-1/2 x 6" red packing list envelopes are pre-printed with "Invoice Enclosed" across the full face in bold text, delivering instant visual identification on outbound shipments. The high-contrast red stock and prominent imprint let warehouse staff, carriers, and recipients locate invoice documents without touching or rotating the outer carton.
The pressure-sensitive adhesive backing bonds reliably to corrugated boxes, poly mailers, and rigid surfaces, eliminating tape or secondary fasteners. Side-opening construction along the 4-1/2" dimension accommodates standard documents folded to fit. E-commerce fulfillment centers, wholesale distributors, manufacturers, and retail shippers use these envelopes wherever consistent, visible document attachment is required on every outbound package.
Envelopes are sold in cases of 1,000 and ship via parcel carrier. The case format supports high-volume shipping environments that cycle through document pouches quickly and need a dependable restocking unit.
