Description

These 4-1/2 x 6" red "Important Papers Enclosed" envelopes secure and visibly flag critical shipping documents on the exterior of outbound packages. The bold red color and pre-printed message allow recipients, carriers, and warehouse staff to identify document pouches instantly — no need to open the shipment to locate paperwork.

Common applications include e-commerce order fulfillment, import/export shipping, wholesale distribution, and manufacturing operations where invoices, packing slips, customs declarations, and compliance documents must accompany every shipment. The exterior placement keeps documents accessible at every handling point along the supply chain.

Each envelope measures 4-1/2 x 6" (exterior) and opens along the 6" side for document insertion. The permanent adhesive backing bonds to corrugated boxes, poly mailers, and rigid outer packaging. Sold in cases of 1,000 envelopes and ships via parcel carrier.
