These 5-1/2 x 10" orange envelopes are printed with "Instructions Enclosed" in bold text, giving receiving staff and handlers an immediate visual cue that a shipment requires attention before unpacking. The high-visibility orange stock is purpose-built for fast identification in busy dock and receiving environments.
The pressure-sensitive adhesive backing bonds directly to corrugated cartons, poly mailers, stretch wrap, and most common shipping surfaces without tape or additional hardware. Manufacturers, third-party logistics providers, and retailers use these envelopes to attach assembly guides, safety data sheets, compliance documents, and setup instructions to outbound shipments.
Each envelope is constructed from 2-mil material and opens along the 10" dimension, accommodating standard letter-size documents folded once to fit. Exterior dimensions are 5-1/2 x 10". Cases contain 1,000 envelopes and ship via parcel carrier.
